Clinical & Coding Specifications

Clinical Context

A 72-year-old patient with progressive mobility impairment due to advanced Parkinson disease and postural instability is evaluated for durable medical equipment. The patient has significant trunk instability and risk of pressure injury from prolonged sitting. A physical medicine and rehabilitation clinician performs an in-person evaluation, documents functional limitations, measurements, and justification for a manual adult-size wheelchair with tilt-in-space to optimize pressure redistribution and safe sitting balance. The ordering process includes the clinician’s evaluation note, a detailed mobility assessment, seating and positioning needs, and measurement documentation. A supplier verifies the prescription, performs a trial or fitting when indicated, delivers the wheelchair to the patient’s home or outpatient clinic, provides training for the patient and caregiver on safe transfers and tilt operation, and documents delivery and education. Follow-up occurs through outpatient therapy or home health to assess fit, skin integrity, and wheelchair function.
