Clinical & Coding Specifications
Clinical Context
A 42-year-old patient with advanced amyotrophic lateral sclerosis (ALS) has progressive loss of upper extremity motor control and limited ability to operate conventional wheelchair joysticks. The durable medical equipment (DME) team evaluates the patient in an outpatient rehabilitation clinic. An occupational therapist performs a seating and mobility assessment, documents the need for a power wheelchair accessory that enables head-operated proportional control to maintain independent mobility. The supplier configures the mechanical head control interface, integrates the proportional electronics and direction change switch, mounts the device to the wheelchair frame, and provides patient and caregiver training during an in-person delivery visit. Typical paperwork includes the patient-specific mobility assessment, prescription signed by the treating physician, documentation of functional limitations, and supplier delivery and setup notes. Expected sites of service are outpatient rehabilitation clinics, DME supplier facilities, or patient homes for delivery and setup visits.
