Summary & Overview
HCPCS E2631: Wheelchair Accessory, Elevating Proximal Arm
HCPCS Level II code E2631 denotes a wheelchair accessory — an addition to a mobile arm support that provides an elevating proximal arm. Nationally, this code captures claims for a component that enhances upper-limb positioning and support for wheelchair users, affecting durable medical equipment billing and mobility accessory coverage decisions. Coverage and payment for such accessories influence access to assistive technologies for patients with upper-extremity weakness, contractures, or positioning needs.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of where this code fits within durable medical equipment billing, typical sites of service, and the clinical context for use. The publication provides benchmarks for coverage expectations, common billing modifiers used with DME accessories (listed separately), and policy considerations that payers and providers monitor when processing claims for wheelchair components.
This summary equips clinicians, DME suppliers, and billing professionals with the essential context for E2631: what it represents, why it matters for mobility and positioning services, and what to expect from payer coverage patterns and administrative handling at a national level.

Clinical & Coding Specifications
Clinical Context
A 72-year-old male with hemiparesis after a left hemispheric stroke presents to an outpatient durable medical equipment (DME) clinic for wheelchair optimization. The patient uses a power wheelchair for community mobility but has limited active elbow flexion and proximal arm elevation on the affected side, causing difficulty positioning the forearm for feeding and tablet use. The clinician evaluates the mobility device and determines that adding an elevating proximal arm support accessory will improve resting position and facilitate transfers and activities of daily living. The DME supplier documents the patient’s functional deficit, mobility device details, measurements, and justification for the accessory. The accessory E2631 is ordered and fitted at the DME facility; a certified orthotist or wheelchair technician adjusts the mount, confirms safe operation in clinic, provides patient training, and completes the required delivery and set-up documentation. Follow-up occurs with the referring rehabilitation physician or occupational therapist to confirm improved arm positioning and function.
