An Assistive Technology Professional (ATP) assessment is required for a custom wheelchair because it serves both clinical and legal-financial purposes. This specialized evaluation ensures the wheelchair is a properly fitted medical device designed for long-term health rather than just a general piece of equipment.

Key reasons for the requirement include:

• Medical Necessity Documentation: Medicare and most private insurance providers mandate an ATP-led evaluation as a core requirement for funding complex rehab technology. The ATP documents your inability to perform mobility-related activities of daily living, which serves as the primary record for medical necessity.
• Clinical Safety and Health: The assessment involves a detailed seating and positioning analysis to prevent secondary complications, such as pressure injuries and skin breakdown, while promoting proper spinal alignment.
• Custom Configuration: A certified ATP analyzes your unique anatomy, posture, and strength to recommend specific technology, such as tilt-and-recline features or alternative drive controls (e.g., sip-and-puff systems), that match your physical needs and daily environment.
• Insurance Approval: Following the evaluation, the ATP compiles clinical data into a detailed justification letter. This documentation package is essential for navigating the funding landscape and securing insurance approval.
