For anyone considering their prosthetic arm options, the question of myoelectric vs body-powered prosthetics is often the first real decision. They work differently, feel different to wear, and are suited to different tasks. Understanding the distinction matters, both clinically and practically.
When comparing myoelectric vs body-powered prosthetics, the key differences come down to control method, physical effort, grip capability, and everyday usability.
Lucas has experienced both body-powered and myoelectric prosthetic arms. Born with a congenital below-elbow upper limb difference, he spent years using body-powered devices before switching to Hero Arm, and more recently, his Hero PRO.
“There was always a sense of separation,” Lucas said about his past body-powered prosthetics. “The cables, the harness, the mechanical clunk every time the hand opened or closed. It worked, but it didn’t feel like me.”
A body-powered prosthetic uses a harness and cable system attached across the shoulders and upper back. When the user moves their shoulder or upper arm, the cable pulls to open or close a hook or mechanical hand. There are no electronics, no battery, and no sensors involved.
For straightforward tasks requiring consistent grip, body-powered devices can be reliable. They are often prescribed early in the rehabilitation pathway as a first prosthetic experience. But the physical demands of the system add up. The harness distributes force across the shoulder and back, which can cause fatigue and long-term compensatory strain. Fine motor tasks are difficult, and the grip is binary: either fully open or fully closed, with little range between.
“It was offered with a heavy body harness most commonly known to be worn by military men,” said Laiken, a Hero Arm user who wore a body-powered device for years after an insurance denial for a myoelectric arm. “It was so heavy and put a strain on the whole body, which seemed so counter-intuitive.”
The social weight was just as significant. “Growing up, the only reason I would wear my prosthetic was to hide my difference,” Laiken said.
John, a Louisiana teen with a congenital limb difference, had a similar experience as a child. He tried a body-powered hook and found it immediately limiting.
“The harness and shoulder movement made everything harder,” John said. “It just felt really limiting.”
Years later, when he researched prosthetic options for a school project, he compared body-powered hooks, aesthetic prosthetics, and myoelectric hands side by side.
“The Hero Arm stood out because it was the most practical and modern,” he said.
A myoelectric prosthetic arm uses electromyography (EMG) sensors placed inside the socket to detect the electrical signals produced when muscles in the residual limb contract. Those signals are amplified and converted into hand movement. There is no harness, no cable pulling across the shoulder, and no external mechanism to operate. The user controls the device through their own muscle activity.
Our Hero Arm is a myoelectric prosthetic available for children as young as age 5, depending on their size. Most new users establish intuitive control within minutes of their first fitting. Sensor placement is mapped to each individual’s strongest muscle signals, and the grip response is proportional: a stronger contraction produces a faster, firmer grip.
For users switching from body-powered devices, the difference in daily experience tends to be immediate.
“Moving to a Hero Arm felt like coming home,” Lucas said about his first myoelectric arm. “I could type, tie laces, or lift a coffee cup with an ease I had never experienced before.”
Richard, who was born with a congenital upper limb difference and had used other devices before the Hero Arm, described the shift in similar terms.
“The Hero Arm is lightweight and the socket is breathable, which makes it comfortable to wear for an entire day, which I couldn’t do with my previous devices,” Richard said. “I’m able to cook, pour drinks, open doors, and complete other tasks with far more ease than I used to. But my new prosthesis hasn’t just brought practical changes. It also has been emotionally liberating.”
Body-powered hooks operate in a single grip pattern. The Hero Arm offers six grip modes: fist, tripod, hook, pinch, index point, and open palm. These are switchable through muscle signals or customized through the Sidekick App.
In practice, that range covers the tasks a single grip pattern cannot. Picking up a glass uses different mechanics than turning a key or typing on a keyboard. The ability to select the right grip for the right task means fewer workarounds and less compensatory strain on the unaffected arm over time.
Sarah, a two-month Hero Arm user, described the relief in simple terms.
“At last I don’t have to chase my bowl around the table, or spill food down my front,” she said.
For users whose daily demands push beyond standard myoelectric function, Open Bionics offers the Hero PRO and Hero RGD.
The Hero PRO closes its fingers more than twice as fast as most competing bionic hands and lifts up to 57 lbs. It is IPX7 water-resistant, charges via USB-C in four hours, and integrates its battery directly into the hand, making it the lightest bionic hand available. Seven grip modes include a precision key grip. The wrist flexes 45 degrees in both directions and rotates 360 degrees manually.
The Hero RGD is designed for physically demanding environments: agriculture, trades, construction, and outdoor work. Its grip closes in 0.4 seconds. It carries up to 77 lbs., and when paired with the Hero Flex socket and MyoPods, the entire system is fully waterproof.
“The first time I tried Hero PRO, it felt natural,” John said. “This was something I could actually use in real life. I can ride a two-wheel bike now. I even hang on a pull-up bar using the hook attachment. And I use a drum attachment for percussion.”
His mother Monica noted a change that went beyond function. “He used to stand always holding his nub and his head kind of down,” she said. “Now you never see him like that anymore.”
One practical argument for body-powered devices was their compatibility with work and activity-specific tools. The Hero PRO addresses this directly. Its USMC-standard wrist connector is compatible with more than 50 Activity Attachments, including work tools, sports grips, and specialist devices, without requiring a socket change.
“You get the intuitive control and comfort of a myoelectric arm and the tool versatility of a body-powered system,” Lucas said. “All without the harness.”
Body-powered prosthetics
Myoelectric prosthetic arms
Which prosthetic arm is right for you? Body-powered devices remain an option for specific scenarios, particularly where simplicity and independence from electronics are priorities. For most people asking the myoelectric vs body-powered question, the capability difference is clear. The more relevant questions are access, clinical fit, and timing.
Robert, who lost his arm in an accident and moved to a myoelectric prosthetic arm within five months, turned down the body-powered device his hospital recommended from day one.
“They said, just get this base model,” Robert said. “As a beginner, just to see if you might like it. I said, no, I am not doing that. I already know that I need something useful.”
Emily Shannon, a certified prosthetist at the Open Bionics Orlando clinic, said that seeking myoelectric care early can make a clinical difference.
“A lot of people think they have to wait a long time after an amputation before they can even start the process,” she said. “But Robert is only five months out and he is already controlling a myoelectric hand and getting a functional socket. More people should know it is not off the table. If you have good healing and good muscle signals, starting early can make a huge difference. It keeps you from forming habits that strain your other arm and it helps you get your life back sooner.”
A consultation with an Open Bionics prosthetist determines whether residual limb length, muscle signal strength, and lifestyle make someone a strong myoelectric candidate. For most below-elbow amputees and those with congenital upper limb differences, the answer is yes.
“For me, switching felt like coming home,” Lucas said. “The arm started to feel like part of me. That is what a prosthetic arm should feel like.”

Many people exploring a prosthetic arm ask the same question early in the process. Does health insurance cover prosthetics, including advanced bionic arms?
In many cases, the answer is yes. Commercial insurance plans frequently cover prosthetic devices when they are considered medically necessary and expected to improve daily function.
Advanced prosthetic technology can support independence, reduce physical strain, and help people perform everyday activities more efficiently. When a prosthesis restores meaningful function and supports long-term musculoskeletal health, insurers may approve coverage.
“Most people assume insurance won’t cover advanced prosthetics, but that’s often not the case,” Elise said. “When the clinical documentation clearly shows how the device improves daily function, many insurers are willing to review and approve coverage.”
Coverage decisions are based on each insurer’s policy criteria, which vary by plan and may differ from clinical recommendations. The approval process typically begins with a clinical evaluation and documentation prepared by your prosthetist and care team.
If you are considering a prosthetic arm through health insurance, the most important first step is a free conversation with a prosthetist.
Insurance providers review several factors when evaluating prosthetic coverage.
These often include:
Prosthetists play a central role in translating a patient’s goals into documentation that insurers can evaluate.
“Our job is to translate a person’s goals into clinical documentation that insurers understand,” Jonah said. “When you clearly show how a prosthesis improves daily activities, it becomes much easier for insurers to evaluate the request.”
Clinical documentation explains how the prosthesis supports everyday tasks such as cooking, carrying objects, using tools, or working safely. Insurers often evaluate how a device helps someone perform activities of daily living and whether it reduces compensatory strain on other parts of the body.
Organizations such as the Amputee Coalition provide additional resources about prosthetic care and insurance coverage for people living with limb loss.
Yes. Many insurance plans approve advanced myoelectric prostheses when they provide measurable functional benefits.
Modern bionic arms use electromyography sensors that detect muscle signals in the residual limb. These signals allow the user to open and close the hand, change grip patterns, and perform precise movements needed for daily tasks.
The Hero PRO is a myoelectric bionic hand designed for real-world activities. It supports tasks such as preparing food, lifting objects, carrying bags, or using tools at work.
The device can carry up to 57 pounds, includes seven grip modes, and features manual wrist flexion and full rotation for natural positioning during everyday movement.
When a prosthesis improves the ability to perform daily activities and reduces long-term strain from compensatory movement, insurers may determine that the device meets medical necessity criteria.
Insurance decisions sometimes require additional review. An initial denial does not necessarily mean a prosthetic device cannot be approved.
Appeals allow clinicians to submit additional documentation explaining the medical need for the device and how it supports functional independence.
“An initial denial is not the end of the process,” Emily said. “With additional documentation and the right clinical support, many patients are able to move forward successfully on appeal.”
Appeals may include:
Experienced prosthetists guide patients through each stage of this process to ensure documentation clearly explains the clinical need for the device.
Cost is one of the most common concerns when someone begins exploring prosthetic technology.
Prosthetic devices vary widely depending on the type of technology and the components required. Mechanical prostheses use simpler systems, while myoelectric devices include sensors, motors, batteries, and customized socket systems.
When insurance approves a prosthetic arm, a significant portion of the device and related clinical care may be covered.
The exact out-of-pocket cost depends on several factors:
Many people find that insurance coverage significantly reduces the overall cost of a prosthetic arm once approval is granted.
Understanding your potential costs typically requires a review of your benefits and clinical documentation with a prosthetist.
Insurance plans may also review coverage for replacement prosthetic devices when a current system no longer meets a user’s needs.
Over time, prosthetic technology advances and a person’s activity level may change. Some individuals develop shoulder strain or back discomfort from years of compensating with one arm.
A modern prosthesis may help redistribute load across the body and support more balanced movement.
Insurance providers may consider replacement when:
A prosthetist can evaluate whether an upgrade may be appropriate based on clinical goals and daily activities.
Navigating insurance approval can feel complicated without guidance.
Certified prosthetists understand how insurers evaluate prosthetic documentation and how to present functional goals clearly.
At Open Bionics clinics, clinicians focus exclusively on upper limb prosthetics. Patients are guided through evaluation, fitting, documentation, insurance submission, and follow-up care.
The goal is to ensure every patient understands their options and receives the clinical support needed throughout the process.
If you are considering a prosthetic arm through health insurance, the most important first step is a conversation with a prosthetist.
Every situation is different. Your goals, daily activities, and long-term health all influence the type of prosthesis that may be appropriate.
A consultation allows a clinician to review your needs, verify insurance benefits, and explain what options may be available.
You do not need to navigate the process alone. Speaking with a specialist can help you understand what coverage may be possible and what the next steps look like.
Does health insurance cover prosthetic arms?
Many commercial health insurance plans cover prosthetic arms when the device is considered medically necessary and expected to improve functional ability. Coverage depends on the policy details, clinical documentation, and the type of prosthesis being requested.
Will insurance pay for a bionic arm?
Some insurance plans review advanced myoelectric prostheses, including bionic arms, when the device supports daily function and long-term physical health. Approval is based on medical necessity and documentation prepared by your prosthetist and care team.
What if my prosthetic claim is denied?
An initial denial does not always mean the request is over. Additional clinical documentation, updated functional evaluations, and the appeals process can help clarify the medical need for the prosthesis.
How long does prosthetic insurance approval take?
Insurance review timelines vary by provider and plan. In many cases, approval takes several weeks after the documentation is submitted. Appeals may extend that timeline.
What does insurance look at when reviewing prosthetic coverage?
Insurers often review medical history, functional goals, daily activity needs, clinical recommendations, and the expected benefit of the prosthesis. They may also consider whether the device helps reduce compensatory strain and improve independence.
Can insurance cover a replacement prosthetic arm?
Yes. Insurance may review coverage for a replacement prosthetic arm when a current device no longer meets the user’s needs, has reached the end of its functional lifespan, or when newer technology better supports daily activities.
For many people recovering from limb loss, the first weeks after surgery are defined by wound care, medical appointments, and the challenge of relearning daily tasks. A bionic arm can feel like a distant goal when getting through the day takes everything available. Yet for many people with a below-elbow limb loss, three months post amputation is when preparation for a myoelectric prosthetic arm can begin.
The choices you make at the three-month mark can set you up for a stronger and smoother bionic journey.
After an upper limb amputation, the residual limb undergoes significant change. Swelling gradually decreases while the limb settles into a more stable shape. This process typically takes three to six months and plays an important role in prosthetic readiness.
A myoelectric prosthetic socket must match the precise shape of the residual limb. If the limb is still changing significantly, the socket fit will change with it. Prosthetists therefore evaluate healing progress and limb volume stability before beginning the fitting process.
If you are around three months post amputation, this may be the right time to begin discussing your prosthetic options. A free consultation with a certified prosthetist can help determine when fitting may be appropriate and how to prepare your residual limb for the best possible outcome.
A shrinker is a compression garment worn over the residual limb to reduce swelling and help shape the limb for a future prosthetic socket. Wearing a shrinker consistently is one of the most effective ways to prepare the limb for prosthetic fitting.
A myelectric prosthetic arm uses sensors that detect electrical signals created when muscles contract. These signals are translated into hand movement. Strengthening the muscles responsible for wrist flexion and extension helps prepare the body for intuitive control once a device is fitted.
Even small muscle contractions matter during early recovery. These signals become the foundation for controlling a bionic hand.
Occupational therapy during early recovery builds strength, coordination, and confidence. Practicing daily tasks and structured exercises prepares the body for the physical demands of prosthetic use.
Emily Shannon, a certified prosthetist, explained the benefit of starting preparation early. “If healing is progressing well and muscle signals are strong, beginning preparation early can make a significant difference in how quickly someone adapts to a prosthetic arm.”
People who define clear goals early in recovery often progress faster. Goals may include returning to work, cooking, participating in sports, or performing specific tasks independently.
Robert, a Jacksonville business owner who lost his arm in an accident, focused on returning to work and fishing again. His clarity about daily needs helped his clinical team identify the right prosthetic solution.
Week 1–6: Healing and swelling management
Month 2–3: Shrinker use and muscle conditioning
Month 3–6: Prosthetic consultation and preparation
Month 4–8: Definitive prosthetic fitting and training
By three months post amputation, many individuals are ready to begin discussing prosthetic options and planning their fitting pathway.
Many people assume they must wait until full healing before speaking with a prosthetist. In reality, early conversations can help guide recovery and allow insurance approval processes to begin sooner. Speaking with a certified prosthetist can help determine when prosthetic evaluation may begin.
How soon after an amputation can you get a prosthetic arm?
Many people begin the evaluation process within three to six months after surgery once healing and limb stabilization occur.
Can you train for a prosthetic arm before fitting?
Yes. Muscle conditioning, shrinker use, and occupational therapy can begin before the first prosthetic socket is fitted.
What is the typical prosthetic arm timeline after amputation?
Many people begin preparation around three months post amputation, followed by prosthetic fitting once healing and limb stability allow.
Preparing early helps ensure the body, muscles, and mindset are ready for the transition to a bionic arm.
Losing a limb is one of the most significant experiences a person can face. Limb loss recovery involves far more than physical healing. It encompasses emotional adjustment, a shift in identity, and the practical challenge of relearning tasks that once felt automatic. The timeline and the experience of limb loss recovery vary widely from person to person.
What has changed considerably in recent years is the technology available to support that recovery. Modern bionic arms have advanced to a point where many people who have experienced limb loss can restore meaningful function, return to work, and engage with the activities that matter most to them.
Limb loss can result from trauma, illness, vascular disease, or complications from conditions such as diabetes. Regardless of the cause, the emotional response is often complex and layered. There is no single or correct way to feel after an amputation.
Common experiences during the early period of limb loss recovery include:
These reactions are a normal part of limb loss recovery. Physical healing and emotional adjustment do not always move at the same pace, and one does not have to be complete before the other begins.
Support networks matter throughout this process. Peer groups made up of people with lived experience of limb loss, clinical rehabilitation teams, and mental health professionals who specialize in adjustment after injury or illness all play a meaningful role. Connecting with others who have navigated a similar journey can be one of the most effective forms of support available.
For peer support resources and guidance on navigating life after limb loss, the Amputee Coalition offers a range of programs and connections to others with lived experience.
For many people, one of the most immediate concerns after amputation is independence. Everyday tasks that previously required little thought — cooking a meal, typing, carrying a bag, fastening buttons, can initially feel out of reach. That experience is common, and it is also temporary for many people.
Modern prosthetic technology has advanced to the point where a significant range of daily tasks can be restored. Advanced bionic arms read muscle signals through EMG sensors placed on the residual limb. Those signals translate directly into finger movement and grip patterns, allowing users to open and close the hand, switch between grip modes, and manipulate objects with a level of control that was not possible a decade ago.
Tasks that users commonly regain with a multi-grip bionic arm include:
A well-fitted bionic arm restores the function and confidence that allows a person to live the life they choose. Robert, a Jacksonville business owner who lost his right arm in an accident and was fitted with a Hero PRO five months later, put it simply. “I get things done,” he said. “Not as fast as I used to, but I’m getting there.”
Open Bionics launched the Hero PRO and Hero RGD in April 2025 following four years of research and development that incorporated feedback from around 1,000 existing users. The devices are two times faster than leading bionic hands on the market and are the only fully wireless and waterproof bionic arms currently available.
The wireless EMG electrode system, called MyoPods, sits on the surface of the residual limb and reads muscle signals without the need for wired connections. That wireless design improves consistency in demanding environments, removing the signal disruption that wired electrode systems can experience.
Conor Cox, a farmer in Kansas who tested the Hero RGD, described using it across a full working day. “I’ve been using the Hero RGD from sun up to sun down for tasks around the farm,” he said. “Whether it’s scooping things out of bunks, shovelling straw, carrying buckets of grain, or working with water. I love that I don’t have to switch prosthetics. This hand does all — lift heavy, waterproof, solid grip.”
Samantha Payne, CEO and co-founder of Open Bionics, said the waterproof design addresses a problem that has affected bionic arm users for years. “All componentry is held in the palm of the hand, making it the first design ever built to house a battery enabling wireless control and importantly enabling amputees to be able to get it wet without worrying about frying electronics,” she said.
The devices are also the first to use a USMC-standard wrist connector, allowing users to switch between a bionic hand and a sports or activity attachment in a few clicks. Rather than carrying multiple prostheses for different environments, a single arm can now serve both daily life and physical activity.
Limb loss recovery involves more than restoring physical function. For many people, it also means rebuilding a sense of identity and confidence in how they engage with the world around them.
Historically, prosthetic devices were designed to look as close to a natural limb as possible. The assumption was that concealment was preferable. That assumption has shifted considerably. Many people today choose prosthetics that express their personality rather than hide their difference.
Open Bionics devices can be fitted with customizable magnetic covers in a range of colors and designs, including officially licensed superhero designs. For many users, the ability to personalize their device changes how they feel wearing it and how others respond to it. The prosthesis becomes a point of identity and pride rather than something to minimize.
For Kristin, the shift from being cared for to caring for others again is what recovery ultimately meant. “I love paying it forward,” she said. “If someone out there is like I was, unsure where to start, maybe my story will reach them. Maybe they’ll get to experience independence again too.”
Limb loss recovery takes time, and it looks different for everyone. With the right clinical support and access to technology that fits how you actually live, many people return to work, resume hobbies, pursue physical challenges, and build lives that look a lot like the ones they had before. Robert was back in consultation five months after his accident. Kristin was eating mints independently in front of her favorite show, something she had not been able to do since 2022.
Open Bionics operates specialist clinical sites dedicated exclusively to upper limb prosthetics, with locations across the United States. Every device is custom-fabricated to the individual’s residual limb and regulated to FDA medical standards. Devices are PDAC approved and covered by multiple reimbursement pathways including Medicare and Medicaid.
The journey after limb loss looks different for everyone. What remains consistent is the goal: restoring independence, confidence, and the freedom to live on your own terms.

Remington was nine years old, born without a hand, and had clinical evidence supporting her need for a bionic arm. Her insurer, Select Health, denied the claim anyway, classifying a Hero Arm as not medically necessary. Her mother Jami described the decision plainly. “This device has a huge impact on her health and well-being, and that is what the insurance was supposed to deliver,” she said.
The family launched a GoFundMe campaign that went viral within hours, raising over $30,000. A company called CrowdHealth stepped in to cover Remi’s Hero Arm in full. Remi used the donated funds to buy a Hero Arm for Taj, an eight-year-old in Maryland who had faced the same denial. The GoFundMe has since raised over $50,000, enough to fund a third child’s device. “People shouldn’t have to have fundraisers to pay for something this important to a child’s health and well-being,” Jami said in a Washington Post interview. You can read Remi’s full story on the Open Bionics blog.
Remi’s case attracted national attention and sparked a broader conversation about how prosthetic insurance coverage works in practice. Coverage for advanced bionic arms varies significantly by insurer and plan. Documentation requirements are extensive, and initial denials are not uncommon. Understanding the process, and knowing what steps to take at each stage, can make a meaningful difference in outcome.
Prosthetic insurance coverage for advanced myoelectric devices requires documentation that establishes medical necessity. The standard varies by insurer and policy, but most claims involve a physician prescription outlining the clinical need, a formal clinical evaluation from a certified prosthetist, a functional assessment documenting current limitations and anticipated gains, and prior authorization before the device is ordered or fabricated.
Completing each of those steps does not guarantee approval. Insurers retain the right to interpret medical necessity according to their own policy criteria, which can differ significantly from clinical standards or the judgment of the treating team. Natalie, a Hero Arm user who went through a nine-month process before her initial claim was denied, said the experience revealed how disconnected insurer criteria can be from clinical reality. “It was fascinating that they wanted to know if I could open a jar beforehand,” Natalie said. “It makes me think that insurance doesn’t know what to ask or what is actually useful.”
Over 70 percent of Hero Arm orders across the United States are ultimately funded by insurance. Approval is achievable, but it often requires persistence, documentation, and clinical support throughout the process.
One of the most common grounds for denial is a determination that the device is cosmetic rather than medically necessary. For advanced bionic arms, this classification does not always reflect current clinical standards and can be reviewed through the appeals process.
Nicola, a bartender in New York City who pursued insurance approval for four years across three separate denials, described the frustration of that process directly. “Who are these people sitting behind a desk to tell me what I need and I don’t need?” she said. “You don’t even know what my day-to-day looks like to even make that judgment.”
Prosthetic insurance coverage outcomes vary considerably by plan and individual circumstances. Jackson’s claim was approved without issue. Nicola’s took four years and three denials. The difference between those outcomes comes down to the insurer, the policy language, and the quality of documentation prepared at each stage.
The cosmetic classification sometimes reflects policy language that predates recent advances in prosthetic technology. Open Bionics clinicians regularly identify appeals where the denial cites research that is no longer current, and use that gap as the basis for challenge.
Not every claim follows that path. Jackson, a 17-year-old high school athlete from San Jose, California, was born with a congenital right below-elbow limb difference and had tried several body-powered devices before discovering Open Bionics. He scheduled a free consultation at the Open Bionics clinic in Los Angeles, and his bionic arm was approved by health insurance without issue. “People are always curious, and I don’t mind talking about it,” Jackson said. “It just makes everything feel easier. I don’t have to plan around it as much.”
The difference between Remi’s experience and Jackson’s is not the device, the clinical need, or the quality of the application. Coverage outcomes vary by plan and by insurer, which is why strong documentation, clinical support, and familiarity with the appeals process matter so much from the outset.
A denial is not the end of the process. Most insurance policies include an appeals pathway, and a well-constructed appeal with strong clinical documentation has a meaningful chance of overturning the original decision. The strongest appeals engage directly with the insurer’s stated criteria rather than restating the original submission. If a denial cites outdated research or applies a definition of medical necessity that does not reflect current clinical evidence, the appeal addresses that gap with current peer-reviewed literature.
Logan’s prosthetic insurance coverage process started when he was ten years old and born without his left arm, when his mother Stacy began the process of obtaining a Hero Arm through the Open Bionics clinic in Orlando. Emily Shannon told Stacy upfront that a denial was likely and began preparing the appeal before it arrived. “Emily really set the expectations,” Stacy said. “She let us know that insurance would probably deny this right out of the gate, but I am going to work with you to appeal it.” Within days of receiving the denial letter, they had compiled clinical references and narratives justifying the device. Stacy wrote a supporting letter and Logan’s physician provided documentation. The appeal succeeded.
“It was really discouraging at first,” Stacy said. “But if we can fight this, others can fight this.” In her letter to the insurer, she pushed back on the experimental classification directly and argued the clinical necessity of the device. After the appeal was approved, Stacy had a message for other families in the same position. “Even if you don’t feel like you have the right to have a voice, you do,” she said. “And you have to fight for you.” Read Logan’s full story here.
Nicola’s case at the Open Bionics clinic in New York involved three denials over four years before her claim was finally approved. She had first tried to access a bionic arm in 2020. By the time she reached Open Bionics, her sound arm had begun showing early signs of arthritis from overuse. “There were quite a few times I thought this was never going to happen,” she said. Persistence and preparation across each stage of the appeal process ultimately changed the outcome. Read more about fighting insurance denials state by state.
For patients whose prosthetic insurance coverage through a private plan does not extend to advanced devices, government reimbursement programs offer an additional route. Open Bionics devices are PDAC approved and covered by multiple reimbursement pathways including Medicare, Medicaid, ChampVA, and Tricare. Aetna, Molina, Humana, and most Medicare Advantage plans have also been consistent in approving Hero Arm coverage.
Coverage policies vary by state and individual plan, and eligibility depends on clinical documentation and functional assessment. A consultation with an Open Bionics clinician can help determine which reimbursement pathways apply to a specific situation and what documentation will be needed to support the claim. The 2025 update to national coding that formally recognized 3D printing as an approved fabrication method for prosthetic devices also strengthened the reimbursement pathway for devices like Hero PRO and Hero RGD. That change is covered in full in the guide to 3D printed bionic arm insurance coverage.
Prosthetic insurance coverage is complex, and a denial can feel isolating. The practical reality is that patients who work with experienced clinical teams, prosthetists who know how to document medical necessity, frame appeals, and engage with insurer criteria, consistently achieve better outcomes than those who navigate the process without that support.
Open Bionics clinicians are involved in the prosthetic insurance coverage process from the initial consultation through to authorization and, where necessary, multiple stages of appeal. The goal is to remove as many barriers as possible between a patient and the device that would most improve their life. Open Bionics data shows that over 70 percent of Hero Arm orders in the United States are ultimately funded by insurance, a figure that reflects years of clinical work building the documentation, precedent, and appeal expertise that makes approvals possible.
If you are exploring prosthetic options and want to understand what coverage may be available to you, book a free consultation with an Open Bionics clinician. The team will walk you through eligibility, documentation requirements, and the reimbursement pathways that apply to your situation.

Are 3D Printed Bionic Arms Covered by Insurance? Here’s What You Need to Know
Taking On Prosthetic Insurance Coverage Denials State-by-State and Winning
Does Health Insurance Cover Prosthetics?
Children with limb differences are active, curious, and constantly developing new skills. Whether a limb difference is present from birth or results from illness or injury, the right prosthetic at the right time can make a meaningful difference in how a child participates in daily life, builds confidence, and experiences the world around them.
Modern prosthetics for children are designed to support movement, comfort, and self-expression during key stages of development. Advances in bionic technology over the past decade have made devices lighter, more capable, and easier to personalize than ever before. For many children and families, those improvements open new possibilities for independence that were not available even a few years ago.
Children learn through movement and play. Activities like riding a bike, carrying a school bag, drawing, playing games with friends, or learning a musical instrument often benefit from two hands. A well-fitted prosthetic can help children take part in those activities more easily and build independence over time.
Prosthetic use also supports emotional and social development. Research on pediatric prosthetic adoption shows links between functional prosthetic use and improved confidence, stronger peer relationships, and greater participation in school and daily life.
Early fitting can play an important role as well. When children begin using a prosthetic device at a young age, myoelectric control often becomes more natural as it integrates into everyday movement patterns. Clinical research consistently supports early fitting where appropriate, and Open Bionics clinicians can advise families on timing as part of the initial consultation.
One of the biggest challenges in pediatric prosthetics is growth. Children grow quickly, which means sockets must be adjusted or replaced more frequently than in adult users. Historically, that created both logistical and financial challenges for families.
Modern fabrication methods have improved that process significantly. We use 3D printing to create custom-fit sockets that match a child’s residual limb precisely. Because each design is stored digitally, clinicians can update or reproduce a socket without restarting the entire fabrication process. That reduces production time and minimizes disruption when fit adjustments are needed as a child grows.
The Hero Arm is available for children as young as five, making it one of the few multi-grip myoelectric bionic arms designed and clinically approved for pediatric use. We operate 12 specialist clinics focused exclusively on upper limb prosthetics across the United States.
Our Hero Arm uses EMG electrodes that sit on the surface of a residual limb. Those sensors detect small muscle signals generated when a child contracts muscles in their arm. The system translates those signals into finger movement and grip patterns in the bionic hand.
Most children learn to control the device quickly. With practice and guidance from our clinicians, muscle control becomes intuitive and responsive. The wireless design removes one of the most common sources of reliability problems in earlier myoelectric systems, and the lightweight construction reduces the fatigue that leads to reduced wear time in heavier devices.
In April 2025, we introduced the Hero PRO and Hero RGD, following four years of development and feedback from around 1,000 users. Both devices are fully wireless and waterproof, and operate more than twice as fast as many existing bionic hands. Tilly Lockey, who has worn Hero Arms for nine years after losing both hands to meningitis as a toddler, helped test the new devices.
“The arms are so much stronger,” she said. “There literally isn’t a single other arm that can do this. No other arm is wireless and waterproof, and it’s faster than everything else while still being the lightest bionic hand.”
Children commonly use a bionic arm for everyday activities including:
Kiowa is 11 years old and was born with a limb difference on his left side. He spends his days biking, riding horses, practicing taekwondo, and training archery. When his mother Nicole worked with the Open Bionics Los Angeles clinic to apply for a CAF Adaptive Sports Equipment Grant, Kiowa received funding for Hero Flex activity arms that gave him more freedom across every one of those activities.
“He’s always been capable,” Nicole said. “This just gives him more freedom to do what he loves.”
Kiowa’s story is a practical example of how modern pediatric prosthetics have moved beyond everyday function into active, sport-focused use. The Hero Flex socket connects to activity attachments that support cycling, sports training, and other physical disciplines, allowing children to use a single device across a wide range of activities rather than managing separate prostheses for different contexts.
Access to advanced pediatric prosthetics is not always straightforward. Remington Bateman, a nine-year-old from Utah, was denied coverage for a Hero Arm by her insurer, Select Health, which classified the device as not medically necessary. Her family launched a GoFundMe campaign that raised over $30,000 in days. When CrowdHealth stepped in to cover Remi’s Hero Arm directly, the family used the donated funds to purchase a Hero Arm for Taj, an eight-year-old in Maryland facing the same insurance barriers.
Remi’s mother Jami said the family shared their story to raise awareness of a broader problem. “Remi absolutely needs this device to aid her in two-handed tasks and activities,” she said. “It is going to support her spinal and shoulder health as she grows too.”
Elise Dreiling, Remi’s clinician at the Open Bionics clinic in Colorado, said the clinical case for coverage was clear. “After a careful evaluation, we determined that Remi could utilize this technology to great effect,” she said. “It will improve her life and health. We hope insurance companies will begin to approve more devices for upper limb amputees that can significantly impact their health and quality of life.”
Remi’s case is covered in more detail in the blog on prosthetic insurance coverage, which walks through the documentation process, appeals, and available reimbursement pathways including Medicare and Medicaid.
For many children, the appearance of a prosthetic device matters as much as its function. A device a child feels excited to wear is a device that gets worn. Open Bionics built personalization into the Hero Arm from the beginning. Magnetic covers allow children to change the look of their prosthetic across a range of colors and designs, including officially licensed superhero styles.
When a child chooses a design inspired by a favorite character or personal interest, the prosthetic becomes something they proudly show to friends rather than something to conceal. That shift has a meaningful clinical impact. Children who feel proud of their device wear it more consistently, interact with peers more confidently, and are more likely to develop strong myoelectric control over time. Personalization is both an aesthetic feature and a practical factor in long-term outcomes.
Parents and caregivers are central to a child’s prosthetic journey. The fitting process, training period, and daily encouragement all benefit from families who understand what to expect and feel supported by their clinical team. Open Bionics clinicians specialize exclusively in upper limb prosthetics and work with pediatric patients and their families from the initial consultation through long-term follow-up. Every device is custom-fabricated, and the fitting process is designed to be straightforward for both child and parent.
Occupational therapists often support children during the early training period, helping develop muscle control, practice everyday tasks, and build confidence with the device. Peer communities of other children and families with similar experiences provide a form of encouragement and practical knowledge that complements clinical support.
With the right device, the right clinical team, and an environment that encourages use, many children with limb differences grow up pursuing sports, creative interests, and careers without meaningful limitation.
