Health Insurers Question the Necessity of Prosthetic Limbs: What You Need to Know

Health Insurers Limit Coverage of Prosthetic Limbs, Raising Concerns Over Medical Necessity

In 2023, Michael Adams, 51, was searching for a health insurance plan with one essential requirement: coverage for prosthetic limbs. This wasn't just a preference for Adams—it was a necessity. After losing his right leg to cancer 40 years ago, Adams has lived through the challenges of using a prosthetic limb and has experienced the impact of microprocessor-controlled knees, which add stability and prevent falls. However, when the time came to replace his old leg in January 2023, he found that his health insurer denied the claim. Despite Colorado state law determining medical necessity should be left to the patient’s doctor, his insurer deemed the $50,000 prosthetic leg unnecessary.

Adams' experience is not an isolated case. For those relying on prosthetic limbs, the struggle to secure proper coverage from health insurers has been an ongoing issue. Many insurance plans place heavy restrictions or impose unreasonable caps on prosthetic coverage, even for devices like microprocessor-controlled knees that have been in use for years.

The Disparity Between Prosthetic and Joint Coverage

People needing joint replacements rarely encounter the same level of pushback. In 2021, approximately 1.5 million knee or hip replacements were performed in the United States, according to the Agency for Healthcare Research and Quality (AHRQ). The cost of a total knee or hip replacement typically hovers around $68,000. Health plans generally cover these surgeries, though they often negotiate lower rates with hospitals. In stark contrast, prosthetic limbs like Adams' microprocessor-controlled knee often face more stringent approval processes and higher out-of-pocket costs, even though they provide similar life-altering benefits.

The discrepancy in coverage is seen by many as discrimination against those with limb loss. As Jeffrey Cain, a family physician and former board chair of the Amputee Coalition, noted, "Insurance covers a knee replacement if it's covered with skin, but if it's covered with plastic, it's not going to cover it."

The Problem of Access and Insurance Challenges

Ashlie White, chief strategy officer at the Amputee Coalition, explained that while many health plans include basic prosthetics coverage, insurers often impose restrictions, such as limiting the types of devices covered or setting caps on the amount they’ll pay for prosthetics. This has led to a situation where approximately 2.3 million people in the U.S. live with limb loss, yet fewer than half have been prescribed a prosthesis. The issue is expected to worsen as the aging population grows, with a higher number of people losing limbs due to conditions like diabetes, trauma, or poor circulation.

For people like Adams, the cost of the prosthetic is often a significant barrier, even with insurance coverage. After appealing his insurer’s initial denial, Adams was ultimately required to pay a coinsurance payment of about $4,000 for his new prosthetic leg. While he was fortunate to afford this, many others, like Leah Kaplan, find themselves in a much more difficult financial position.

Kaplan, 32, was born without a left hand and had previously avoided using a prosthetic device. However, a few years ago, she opted for a prosthetic hand specifically designed for cycling, which was covered by her health insurance. When she sought approval for a myoelectric prosthetic hand for everyday use, her insurer denied it, claiming the device wasn’t medically necessary. With the myoelectric hand priced at over $46,000, Kaplan found herself stuck between the need for the prosthetic and her inability to afford it without insurance coverage.

The Legal Landscape of Prosthetic Coverage

In 2000, Colorado passed a law requiring insurers to cover prosthetic arms and legs on par with Medicare. This law, as well as similar laws in other states, aimed to ensure fairness in insurance coverage. Despite these efforts, the coverage and reimbursement for prosthetic limbs still remain inconsistent, especially for people in private insurance plans not governed by state laws.

Although federal programs like Medicare cover prosthetic limbs with an 80% reimbursement, the reality for many beneficiaries is that prosthetic limbs are still inaccessible. A 2020 report from the Government Accountability Office found that only 30% of individuals who lost a limb in 2016 received a prosthetic limb in the following three years. With costs for high-end prosthetics continuing to climb, many patients are left with minimal options.

The Psychological and Physical Impact of Inadequate Prosthetic Coverage

For individuals living with limb loss, having access to a functional prosthetic limb is essential for maintaining independence and quality of life. Microprocessor-controlled knees, like the one Adams uses, offer life-changing improvements, helping prevent falls and improving mobility. Without these devices, patients may be forced to rely on outdated prosthetics that are far less effective, severely limiting their physical capabilities and psychological well-being.

In Kaplan’s case, the lack of coverage for her prosthetic hand has caused emotional distress. After waiting for years to get the right prosthesis, she has now been denied coverage three times. While she continues to appeal the insurer’s decision, the waiting game has taken a toll on her, both financially and emotionally.

The Need for Reform in Prosthetic Coverage

The current state of prosthetic limb coverage highlights a need for significant reform in both insurance practices and public policy. Advocacy groups, such as the Amputee Coalition, continue to fight for better coverage and fairness in health insurance for people with limb loss. More comprehensive legislation that mandates full coverage for advanced prosthetics, as well as improved access to insurance plans that provide better reimbursement, is needed to address the disparities in care.

Conclusion

As the population continues to age and more people experience limb loss, the need for fair and consistent coverage of prosthetic limbs becomes even more pressing. People like Michael Adams and Leah Kaplan are just a few examples of the challenges faced by those living with limb loss. Ensuring that prosthetics are covered as medically necessary by insurance companies will not only improve quality of life for these individuals but will also provide a more equitable healthcare system for all.
