Summary & Overview
HCPCS L1681: Hip Orthosis, Bilateral, Postoperative Abduction
HCPCS Level II code L1681 identifies a prefabricated hip orthosis for bilateral hip joints and thigh cuffs that is customized to fit the patient and offers adjustable control of flexion, extension, and abduction. This code is used to document provision and customized fitting of a postoperative hip abduction orthosis used in recovery from hip surgery, dislocation risk management, or other conditions requiring controlled hip motion. Nationally, utilization of orthotic devices such as this affects postoperative rehabilitation pathways, device coverage determinations, and durable medical equipment spending.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for L1681, commonly reported sites of service, and the typical service type. The publication presents benchmarks and payment policy context where available, highlights relevant billing considerations for hospitals and outpatient orthotics providers, and summarizes common modifier and claim-line considerations when a customized prefabricated orthosis is furnished. Data not available in the input is identified explicitly.
This summary is intended for clinicians, billing specialists, and policy analysts seeking a concise reference to HCPCS Level II code L1681, its clinical role in postoperative hip care, and the payer landscape that commonly governs coverage and claims processing.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents to an orthopedic postoperative clinic seven days after total hip arthroplasty complicated by intraoperative soft-tissue laxity and a high risk for early dislocation. The surgeon orders a postoperative hip abduction orthosis to limit hip flexion, extension, and control abduction while protecting the surgical construct. A certified orthotist evaluates the patient in the outpatient clinic, selects a prefabricated bilateral hip orthosis (L1681), and trims, molds, and adjusts the hip joints and thigh cuffs to the patient’s anatomy. The orthotist documents measurements, component adjustments, range-of-motion stops, and patient education on donning/doffing and skin checks. The device is issued and fitted in the clinic; follow-up visits include reassessment of fit, adjustment for swelling changes, and documentation of continued medical necessity for coverage and durable medical equipment billing workflows.
