Medicare does cover hospital beds for home use, but only when a doctor certifies the bed is medically necessary. Coverage falls under Part B as durable medical equipment (DME), and you’ll typically pay 20% of the Medicare-approved amount after meeting your annual deductible. The key factor isn’t your diagnosis alone but whether your medical condition requires body positioning that an ordinary bed simply can’t provide.
What Medicare Requires for Approval
To qualify, your doctor must document that you need a hospital bed for at least one of these reasons: your condition requires body positioning that isn’t possible in a regular bed (to relieve pain, maintain alignment, or prevent complications like respiratory infections), you need the head of the bed elevated more than 30 degrees most of the time due to heart failure, chronic lung disease, or aspiration risk, or you need traction equipment that can only attach to a hospital bed.
The condition must be expected to last at least one month. Your doctor fills out a Certificate of Medical Necessity, a standardized form that asks specific yes-or-no questions about your positioning needs, diagnosis codes, and estimated length of need (which can range from one month to lifetime). The doctor must personally sign this form; signature stamps aren’t accepted, and while other clinicians can help complete it, the ordering physician is ultimately responsible for reviewing and signing off.
Common qualifying conditions include cardiac disease, chronic obstructive pulmonary disease, quadriplegia or paraplegia, stroke recovery, and severe arthritis. But the diagnosis alone isn’t enough. The documentation must describe the severity and frequency of your symptoms and explain why a regular bed won’t work.
Which Bed Types Are Covered
Medicare distinguishes between several categories of hospital beds, and not all are treated equally.
- Fixed-height hospital beds are the baseline. If you meet the medical necessity criteria above, this type is covered.
- Variable-height hospital beds are covered when you also need the bed at a specific height to transfer to a wheelchair, chair, or standing position. Qualifying conditions include severe arthritis, fractured hip, serious cardiac conditions where straining to get up is dangerous, spinal cord injuries, multiple limb amputation, and stroke.
- Semi-electric hospital beds are covered when you need frequent body position changes or may need an immediate position change with no delay. You must be able to operate the controls yourself, though exceptions exist for spinal cord injuries and brain injuries.
- Heavy-duty and extra-heavy-duty beds are covered for patients weighing between 351 and 600 pounds, or over 600 pounds respectively.
- Fully electric hospital beds are not covered. Medicare considers the electric height adjustment a convenience feature rather than a medical necessity. Claims for total electric beds will be denied.
This distinction between semi-electric and fully electric trips up a lot of people. A semi-electric bed lets you electronically raise and lower the head and foot sections but uses a manual crank for overall bed height. That’s the most advanced option Medicare will pay for in most situations.
What You’ll Pay Out of Pocket
Hospital beds fall under Part B’s standard cost-sharing rules. You first need to meet the annual Part B deductible, which is $240 in 2024. After that, you pay 20% of the Medicare-approved amount for the equipment. Your supplier must accept assignment, meaning they agree to the Medicare-approved price as full payment, for these numbers to hold.
Medicare treats hospital beds as “capped rental” items. Rather than buying the bed outright, Medicare pays a monthly rental fee. After 13 consecutive months of rental, ownership of the bed transfers to you at no additional cost. During those 13 months, you’re responsible for your 20% coinsurance on each monthly payment. If you have a Medigap (supplemental) plan, it may cover some or all of that 20%.
Accessories and Mattress Coverage
Medicare also covers pressure-reducing support surfaces, including specialized mattresses and mattress overlays, when prescribed by your doctor for preventing or treating pressure sores. These are covered separately as DME under Part B with the same 20% coinsurance. Some types of pressure-reducing surfaces, like powered air flotation beds, require prior approval before Medicare will pay. Depending on your state, up to five categories of support surfaces may need prior authorization.
Medicare Advantage Plans
If you’re enrolled in a Medicare Advantage plan (Part C) rather than Original Medicare, your plan is required to cover everything Original Medicare covers, including medically necessary hospital beds. However, there’s a practical difference: Medicare Advantage plans often require prior authorization before approving DME. This means your supplier or doctor may need to submit the request and wait for plan approval before delivering the bed. The coinsurance amount may also differ from the standard 20%, depending on your specific plan’s terms.
Choosing a Supplier
You can’t just buy a hospital bed from any retailer and expect Medicare to reimburse you. The supplier must be enrolled in the Medicare program as a DMEPOS supplier, which requires accreditation from a CMS-approved organization and a $50,000 surety bond. If you get a bed from a non-enrolled supplier, Medicare won’t pay anything toward it.
You can search for Medicare-enrolled suppliers in your area through Medicare.gov’s supplier directory. Before ordering, confirm with the supplier that they accept Medicare assignment and verify that the specific bed type your doctor prescribed is the type they’ll deliver. A mismatch between what’s on the Certificate of Medical Necessity and what shows up at your door can result in a denied claim.
