Short answer up top, then the exact rule. Here's what Original Medicare does and doesn't cover for prosthetic devices in 2026 — and where a Medicare Advantage plan can fill the gap.
Quick answer: Yes. Medicare Part B covers medically necessary artificial eyes, legs, and arms when your doctor orders them. After the Part B deductible you pay 20% of the Medicare-approved amount — and you must use a supplier that participates in Medicare.
Medicare Advantage (Part C) plans must cover prosthetic devices too, but your cost-share, supplier network, and prior-authorization rules are set by the plan — confirm the plan's rules and use in-network suppliers before ordering.
Amputees and anyone who needs an artificial eye or limb. The device is covered, but the 20% coinsurance on a prosthetic can be a real number — a Medigap plan can pick up part or all of it. Always confirm the supplier participates in Medicare before you commit.

See 2026 Medicare Costs →Yes. Part B covers medically necessary artificial legs (and arms and eyes) when your doctor orders them. You pay 20% of the Medicare-approved amount after the Part B deductible. Some states require prior authorization for certain lower-limb prosthetics.
After you meet the Part B deductible, you pay 20% of the Medicare-approved amount, and Medicare pays 80% — but only if the supplier participates in Medicare. A Medigap plan can cover part or all of your 20% share.
