Short answer up top, then the exact rule. Here's what Original Medicare does and doesn't cover for a pressure-reducing mattress in 2026 — and where a Medicare Advantage plan can fill the gap.
Quick answer: Yes. Part B covers pressure-reducing support surfaces — certain beds, mattresses, and mattress overlays that prevent or treat pressure sores — as durable medical equipment. Certain types require prior authorization before Medicare will pay. You pay 20% after the Part B deductible.
Medicare Advantage plans cover the same equipment but layer their own prior-authorization process and supplier network on top of Medicare's. With this item that means two approvals can be in play at once — ask the supplier to confirm the plan's authorization is on file before the bed or mattress is delivered.
Caregivers of someone confined to bed, and anyone healing a pressure ulcer at home. The failure mode here isn't coverage — it's paperwork: equipment delivered before the required prior authorization is approved is the most common reason a covered surface goes unpaid.

See 2026 Medicare Costs →Yes, when it qualifies as a pressure-reducing support surface prescribed to prevent or treat pressure sores. Certain powered types — like powered air flotation beds and some mattresses and overlays — require prior authorization before Medicare pays. You pay 20% of the Medicare-approved amount after the Part B deductible.
It means Medicare has to approve the item before you get it. For certain pressure-reducing support surfaces, the supplier submits the request and documentation up front; if the equipment is delivered without that approval, the claim can be denied and you can be left with the bill.
