Yes, according to Medicare guidelines, Mobility Related Activities of Daily Living (MRADLs) deficits must be documented as occurring specifically and exclusively within the home.

Medicare’s "within the home" rule is the foundation of the medical necessity determination. To meet the primary coverage criteria for a power wheelchair, your medical records must demonstrate an inability to perform daily mobility tasks inside your residence.

Key details regarding this requirement include:

• Primary vs. Secondary Criteria: Documentation of in-home deficits (such as difficulty with bed mobility or transfers in the bathroom) is the primary basis for coverage. Community mobility challenges, such as navigating parking lots or uneven terrain, are considered secondary and cannot solely justify the need for a power wheelchair.
• Specific In-Home Locations: Clinicians must evaluate and document your functioning in specific areas of the home, such as the bedroom, bathroom, kitchen, and hallways.
• Observable Limitations: The medical record must capture specific limitations, such as an inability to propel a manual wheelchair across a kitchen floor or requiring caregiver assistance to access the bathroom.

Failing to provide detailed notes confined to the living quarters often results in insurance denials, as Medicare reviewers primarily look for evidence that the device is necessary for safe and dignified home life.
