Does Medicare Cover an Air-Fluidized Bed?

Is an air-fluidized bed covered by Medicare?

Yes. An air-fluidized bed is covered under Medicare Part B as durable medical equipment (DME). Part B — not Part A — is the part that pays for medical equipment a doctor prescribes for use in your home. The air-fluidized bed also appears on Medicare's Durable Medical Equipment Reference List, which confirms it is a covered DME item subject to Medicare's specific coverage rules for these beds.

An air-fluidized bed is a specialized, heavy bed that suspends the body on a flow of temperature-controlled air pushed through fine silicone beads. It is used to treat very serious pressure ulcers (bedsores) by reducing pressure on the skin. It is not the same thing as a standard hospital bed or a powered air flotation bed — those are different products with their own coverage rules.

Because this is high-cost equipment used for serious wounds, Medicare applies a detailed National Coverage Determination (NCD 280.8). Meeting the general DME rules is not enough; you must also meet every medical criterion below.

What you pay in 2026

An air-fluidized bed is covered under Part B, so the standard Part B cost-sharing applies. You first pay the Part B annual deductible, then a share of the Medicare-approved amount.

• Part B deductible (2026): $283 per year — you pay this before coinsurance begins.
• Coinsurance: After the deductible, you pay 20% of the Medicare-approved amount, and Medicare pays the other 80% (when the supplier accepts assignment).
• Part B premium (2026): The standard monthly premium is $202.90; you must keep Part B active to have this DME coverage. Higher-income beneficiaries may pay more (IRMAA).
• Assignment matters: Use a Medicare-enrolled supplier that accepts assignment. If a supplier does not accept assignment, you could pay more.
• Rent vs. buy: Depending on the equipment type, Medicare may have you rent the item, buy it, or choose between renting and buying. Your supplier can tell you which applies.

Medical criteria you must meet (NCD 280.8)

Medicare covers a home air-fluidized bed only for patients with severely limited mobility who have a Stage III or Stage IV pressure ulcer and who are being cared for in a non-institutional (home) setting. In addition, all of the following must be true before the bed is authorized:

• Failed conservative treatment first: You must have completed a comprehensive ulcer-treatment program — including frequent repositioning (about every 2 hours), use of a Group II support surface, treatment of any wound infection, nutritional optimization, and debridement — without adequate improvement.
• Alternatives ruled out: All other alternative equipment must have been considered and ruled out before the air-fluidized bed is approved.
• Physician-directed care: A physician must direct the home treatment regimen and reevaluate and recertify the continued need for the bed on a monthly basis.
• Written order before delivery: A written order from the attending physician must be given to the supplier before the equipment is delivered for Medicare to pay.
• Suitable home: Your home must be able to physically support this very heavy bed (an air-fluidized bed can weigh around 1,600 pounds), have adequate electrical capacity, and have a caregiver available.

When Medicare will NOT cover the bed

Even if you have a Stage III or IV ulcer, certain situations make a home air-fluidized bed not covered:

• Coexisting pulmonary (lung) disease: Home use is not covered, because the lack of firm back support makes coughing ineffective, and inhaling the dry air can thicken pulmonary secretions.
• Unprotected wet or moist dressings: Not covered if you need wet soaks or moist wound dressings that are not protected by an impervious covering (such as plastic wrap or other occlusive material).
• No qualifying ulcer: Not covered without a Stage III or Stage IV pressure ulcer plus severely limited mobility.
• Not yet tried a full treatment program, or alternatives not ruled out.
• Institutional setting: Coverage under this rule is for the home (non-institutional) setting. If you are in a nursing home, the facility is generally responsible for providing appropriate support surfaces, so a separately covered home air-fluidized bed does not apply.

Prior approval and documentation

Prior approval (prior authorization) is required for certain pressure-reducing support surfaces, such as powered air flotation beds. In some states, prior approval may be required for several types of pressure-reducing support surfaces. Your supplier typically submits the prior-authorization request and the supporting documentation to Medicare before the equipment is delivered.

To support coverage, expect your doctor and supplier to document the ulcer stage, your limited mobility, the comprehensive treatment program you already tried, why alternatives were ruled out, and that your home can support the equipment. The physician must also recertify the continued need each month. Keeping these records complete is the most common factor in whether a claim is paid.

Medicare Advantage and other coverage notes

If you have a Medicare Advantage (Part C) plan instead of Original Medicare, your plan must cover everything Original Medicare covers, including medically necessary DME like an air-fluidized bed. However, costs, supplier networks, and prior-authorization steps vary by plan. Check your plan's Evidence of Coverage and use an in-network DME supplier to avoid higher costs or denials.

Whether you have Original Medicare or a Medicare Advantage plan, the underlying medical criteria for a covered air-fluidized bed are the same. The differences are mainly in cost-sharing and the process you follow. When in doubt, call your plan or 1-800-MEDICARE before equipment is ordered.
