Short answer: Original Medicare does not cover stair lifts, chair lifts installed on stairs, or stairway elevators. CMS classifies stairway elevators as noncovered, and Medicare does not cover structural changes to a home.
Original Medicare coverage
The CMS Durable Medical Equipment Reference List states that stairway elevators are denied. A stair lift is attached to the home and is used to overcome an environmental barrier. It is not treated as portable medical equipment used to diagnose or treat a condition.
This rule is different from coverage of some patient lifts used to transfer a person between a bed, chair, wheelchair, or commode. A covered patient lift must meet separate medical and equipment requirements. It does not include remodeling or a stair lift.
Eligibility and limits
There is no Original Medicare medical-necessity exception that converts a stair lift into covered DME. A prescription or statement that the lift would reduce fall risk does not change its benefit classification. CMS also states that home modifications are noncovered.
Costs
The beneficiary pays the full purchase, installation, electrical, maintenance, and removal costs under Original Medicare. Medicare Supplement insurance generally does not pay for a service that Original Medicare excludes. Other public or community programs may use different eligibility rules.
Medicare Advantage
Some Medicare Advantage plans may offer limited in-home support or home-modification benefits. These are supplemental benefits, not standard Medicare coverage. The plan may limit the amount, vendor, condition, or service area. Written approval should be obtained before installation.
What to do next
- Check the Medicare Advantage Evidence of Coverage for home-safety benefits.
- Ask whether written authorization is required before installation.
- Confirm who owns the equipment and pays for repairs or removal.
- Do not assume a doctor’s order makes a stair lift covered by Original Medicare.
