Readers will find a concise explanation of the clinical purpose of the device, guidance on where the service is typically provided, and an overview of reimbursement and policy considerations relevant to DME and orthotics billing. The publication summarizes standard coding practice, common modifiers in the input, and notes on clinical context such as typical indications for abduction support.
This summary equips billing managers, DME suppliers, and payer policy analysts with the essential information needed to classify and document use of L2310, understand payer coverage landscape at a national level, and locate sections on benchmarks, policy updates, and clinical context in the full publication.

Clinical & Coding Specifications
Clinical Context
A 72-year-old female with advanced bilateral hip osteoarthritis and ambulatory instability presents to an outpatient durable medical equipment (DME) clinic for evaluation of wheelchair accessories after recent discharge from an orthopedic inpatient stay. The patient uses a standard manual wheelchair but has persistent lower extremity adduction and difficulty maintaining leg separation due to spasticity and hip contractures. The treating physical therapist and DME supplier recommend adding an abduction bar to the wheelchair to maintain proper leg alignment, reduce risk of skin breakdown, and improve comfort during transfers.
The clinical workflow includes an evaluation by a licensed physical therapist or rehabilitation physician to document functional limitation, measurements of wheelchair frame and legrest spacing, selection of a straight lower extremity abduction bar, and demonstration of safe use to the patient and caregiver. A supplier orders the part described by HCPCS Level II code L2310 (Addition to lower extremity, abduction bar-straight) and submits the claim with supporting documentation: a physician or therapist face-to-face assessment, a detailed description of need (e.g., spasticity, contracture, adduction), measurements, product model and part number, and photos of current seating if required. The typical site of service is an outpatient DME vendor, either at a clinic-based DME shop or home delivery with in-person fitting and education.
