Limitations in Mobility Related Activities of Daily Living (MRADLs) justify the need for a power mobility device by demonstrating that a patient cannot safely or effectively perform essential self-care tasks within their home using less restrictive means.

According to Medicare guidelines, these limitations justify a power wheelchair based on the following criteria:

• Inability to Use Simple Aids: The documentation must show that the patient is unable to perform one or more MRADLs (such as toileting, feeding, dressing, or bathing) even when using a cane or walker.
• Insufficiency of Manual Chairs: The evaluation must prove that a patient cannot operate a manual wheelchair safely to complete daily tasks due to factors like upper extremity weakness, pain, or lack of endurance.
• Safety and Functional Deficits: Limitations such as unsteady gait, fatigue mid-task, or a high risk of falls during transfers (e.g., from bed to chair) provide the clinical rationale for powered support.
• The "Within the Home" Rule: Justification is specifically tied to deficits occurring inside the residence—such as the kitchen, bathroom, or bedroom—rather than community-based challenges like navigating parking lots.

Ultimately, the record must detail that the power mobility device is necessary to overcome specific physical barriers that prevent a safe and dignified home life.
