HCPCS Level II E2325: Power Wheelchair Sip-and-Puff Interface, Nonproportional
HCPCS Level II code E2325 identifies a nonproportional sip-and-puff interface accessory for power wheelchairs, including electronics, a mechanical stop switch, and manual swingaway mounting hardware. This accessory supports users with severe upper-extremity or hand impairments by enabling alternative control of power mobility, which has implications for independence, mobility access, and durable medical equipment coverage nationally. Payers commonly covering this category include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
This publication explains the clinical purpose of E2325, typical service settings, and the administrative context for billing this HCPCS Level II code. Readers will find an overview of coverage considerations, common billing modifiers, and practical benchmarking topics relevant to durable medical equipment programs. The report is intended for billing managers, DME suppliers, clinical rehabilitation teams, and policy analysts seeking concise guidance on documentation expectations, equipment description, and payer coverage patterns. Data not available in the input will be noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with high cervical spinal cord injury (tetraplegia) presents for power wheelchair control evaluation because hand and shoulder function are insufficient for standard joystick operation. The durable medical equipment (DME) team performs an in-person assessment including seating and mobility evaluation, cognitive and respiratory screening, and demonstration of alternative controls. A nonproportional E2325 sip-and-puff interface is selected when the user requires binary (on/off) control inputs rather than proportional variable-speed control. The supplier configures the interface with all related electronics, a mechanical stop switch for safety, and manual swingaway mounting hardware to attach to the wheelchair frame.
The clinical workflow includes: referral from the treating physiatrist or neurologist; functional assessment by a certified assistive technology professional or occupational therapist; configuration and bench testing of the E2325 accessory; in-clinic training with the patient and caregiver to ensure safe operation and communication of limitations to the prescribing clinician; documentation of medical necessity, starting functional limitations, goals, detailed device description, training notes, and the completed face-to-face encounter; and final delivery with fitting and sign-off by the supplier and ordering clinician.
