Short answer: Original Medicare does not generally cover a walk-in tub, its installation, or bathroom remodeling. Walk-in tubs are household fixtures and do not meet Medicare’s standard definition of durable medical equipment.
Original Medicare coverage
Medicare Part B covers DME that is durable, used for a medical reason, generally useful only to a person who is sick or injured, used in the home, and expected to last at least three years. A walk-in tub remains a bathroom fixture that can be used by people without an illness or injury.
The CMS Durable Medical Equipment Reference List specifically denies bathtub lifts and bathtub seats as convenience or hygiene equipment. Medicare also does not cover home modifications or structural remodeling. A walk-in tub should not be confused with limited covered equipment such as a qualifying commode chair.
Eligibility and limits
A physician’s order or recommendation does not create Original Medicare coverage for a walk-in tub. There is no standard Part B medical-necessity exception for the purchase and installation of this fixture. A seller’s use of terms such as therapeutic, accessible, or senior safety does not determine Medicare coverage.
Costs
The beneficiary pays the full cost of the tub, installation, plumbing, electrical work, permits, maintenance, and later removal under Original Medicare. Medigap generally does not pay for items that Original Medicare does not cover.
Medicare Advantage
A Medicare Advantage plan may offer limited home-safety or in-home support benefits. A benefit is not assumed. It may cover an assessment or a specific modification rather than the full cost of a walk-in tub. Vendor and prior authorization rules may apply.
What to do next
- Read the plan’s Evidence of Coverage for home-safety or support benefits.
- Get written plan approval before signing a purchase contract.
- Ask which item, labor, and installation costs are included.
- Review warranty, cancellation, and property-restoration terms.
