Medicare covers the cost of rollators for those with Part B insurance, according to Medicare.gov. A doctor prescribes the walker for use in the home. The type of rollator determines whether it is purchased to own outright or requires a renting agreement.
Eligible rollators are considered those prescribed and supplied by doctors and suppliers enrolled in the Medicare program, as Medicare.gov explains. Medicare's official website offers a searchable database for participating suppliers of durable medical equipment. As of 2015, Medicare recipients pay 20 percent of the approved amount; however, the cost of the equipment may be more than this amount, and the Medicare recipient is required to pay the remainder.
