Clinical & Coding Specifications
Clinical Context
A 72-year-old patient with chronic mobility impairment uses a manual wheelchair for daily ambulation. During a routine home visit by a durable medical equipment (DME) technician, the front caster wheel shows a worn or damaged removable solid (rubber/plastic) caster tire that impairs smooth steering and increases fall risk. The technician documents the damage, confirms the wheelchair model and caster size, and replaces the single removable solid caster tire. The exchange is billed to the payor using E2221 for the replacement caster tire, with the DME supplier recording the serial/model numbers and photographing the damaged tire for records. When performed in a clinic or outpatient DME service area, the supplier documents the patient identity, prescription or order for replacement, and functional impact (e.g., reduced maneuverability, safety concerns). If clinical staff perform assessment prior to replacement, appropriate evaluation notes and any applicable modifier (for example, 26 if professional component is billed) are appended as required by the payor policy.
