Insurers deny prosthetic limbs as 'not medically necessary' despite decades of use

Private health insurers in the United States routinely deny coverage for prosthetic limbs -- particularly microprocessor-controlled knees and myoelectric hands -- by classifying them as 'not medically necessary' or 'experimental,' even though these devices have been in clinical use for over 20 years. The majority of upper limb prosthetic claims are denied, appealed, and denied again. A GAO report found that only 30% of Medicare beneficiaries who lost a limb in 2016 received a prosthesis within three years. This matters because a prosthetic leg costs $50,000+ and a myoelectric arm costs $40,000-$100,000 -- prices that are catastrophic out of pocket. Without coverage, amputees are confined to wheelchairs or basic devices that severely limit function and independence. The problem persists because over half of Americans with private insurance are in self-funded employer plans exempt from state insurance fairness laws, creating a regulatory gap. Insurers face no penalty for denials because the appeal process is slow, opaque, and stacked against patients who lack legal resources.
