Medicare will pay for a new wheelchair once every five years. This applies to both manual and power wheelchairs, which Medicare classifies as durable medical equipment (DME) under Part B. The five-year clock starts from the date you receive the chair, and replacements before that window close require specific circumstances. Here’s what you need to know about the timeline, the exceptions, and what Medicare expects from you along the way.
The Five-Year Replacement Rule
Medicare considers five years the “useful lifetime” of a wheelchair. Once that period passes, you can qualify for a new one, whether manual or power, as long as you still meet the medical necessity requirements. The replacement doesn’t happen automatically. Your doctor will need to submit a new written order, and you’ll go through the qualification process again.
One small advantage with replacements: if you’re getting a power wheelchair that falls in the same performance group as the one Medicare previously covered, you won’t need a new face-to-face examination. The original exam on file is sufficient. For a wheelchair in a different category or with substantially different features, expect the full evaluation process.
When Medicare Will Pay Before Five Years
You don’t have to wait the full five years if your situation changes. Medicare will consider covering an earlier replacement in a few circumstances:
- Irreparable damage: If the wheelchair is damaged beyond reasonable repair, Medicare can cover a replacement. This includes situations where the cost of repairs would exceed the cost of a new chair.
- Change in medical condition: If your health has changed significantly and your current wheelchair no longer meets your needs, you may qualify for a different type of chair before the five years are up. For example, if you lose the ability to self-propel a manual chair, Medicare may cover a switch to a power wheelchair.
- Stolen or lost equipment: Medicare can cover a replacement if your wheelchair is stolen or lost, though you may need to provide documentation such as a police report.
In each of these cases, your doctor will need to document why the early replacement is medically necessary. The same qualification criteria apply.
Repairs and Parts During the Five Years
Medicare covers repairs to keep your wheelchair functional throughout its useful lifetime. This includes replacement parts like tires, batteries, joysticks, and other components that wear out or break. Medicare pays 80% of the approved amount for repairs, and you’re responsible for the remaining 20%. When a specific part is being swapped for the same type (a worn tire replaced with the same kind of tire, for instance), your supplier uses a specific billing modifier to indicate it’s a wear-and-tear replacement rather than an upgrade.
For power wheelchairs, the rules get more specific around control interfaces. If your condition changes and you need a different type of drive control, say switching from a standard joystick to a head-controlled system, Medicare treats that as a medically necessary modification rather than a full chair replacement.
What You Need to Qualify
Whether it’s your first wheelchair or a replacement, Medicare applies the same medical necessity test. You must have a mobility limitation that significantly impairs your ability to perform everyday activities in your home, things like bathing, dressing, using the bathroom, or getting in and out of bed. A few key conditions must all be true:
- A cane or walker isn’t enough to solve the problem.
- The wheelchair will meaningfully improve your ability to function at home, and you’ll actually use it regularly.
- Your home has enough space for the chair to maneuver through doorways and between rooms.
- You can operate the chair safely, or you have a caregiver who can help.
For power wheelchairs specifically, you must also lack sufficient upper body strength or function to propel a manual chair through a typical day. Medicare views power mobility as the option when manual self-propulsion isn’t realistic.
Your doctor needs to conduct a face-to-face exam before ordering the wheelchair. During that visit, they’ll assess your functional limitations and confirm you can safely use the device. For complex or specialty chairs (like tilt-in-space models), Medicare also requires an evaluation by a physical therapist or occupational therapist who has no financial relationship with the equipment supplier.
What You’ll Pay Out of Pocket
Wheelchairs fall under Medicare Part B, so standard cost-sharing applies. You pay your annual Part B deductible first, then 20% of the Medicare-approved amount for the chair. Medicare covers the other 80%. The “Medicare-approved amount” is either the supplier’s actual charge or the fee Medicare has set for that item, whichever is lower.
Your supplier must accept Medicare assignment, meaning they can only charge you the deductible and the 20% coinsurance. If you have a Medigap or Medicare Advantage plan, your secondary coverage may pick up some or all of that 20%.
Choosing a Supplier
You must get your wheelchair from a Medicare-enrolled DME supplier. Not every medical equipment store qualifies. Medicare has historically used a competitive bidding program to set prices and select contract suppliers in certain areas, though that program is currently in a temporary gap period. During this gap, any Medicare-enrolled supplier can provide wheelchairs, but payment rates are still based on the competitive bidding framework adjusted for inflation.
Before finalizing your order, confirm that the supplier participates in Medicare and accepts assignment. If they don’t, you could end up paying significantly more than the standard 20% coinsurance. Your doctor or the supplier should also verify that the specific chair being ordered fits your home, since Medicare requires a home assessment to ensure the equipment is practical for your living space.
