Summary & Overview
HCPCS L0621: Sacroiliac Orthosis, Flexible Pelvic-Sacral Support
HCPCS Level II code L0621 designates a prefabricated, off-the-shelf flexible sacroiliac orthosis intended to provide pelvic-sacral support and reduce motion at the sacroiliac joint. This orthosis typically includes straps and closures and may feature a pendulous abdomen design to accommodate patient anatomy. Nationally, L0621 is relevant for durable medical equipment (DME) coverage decisions, outpatient orthotics dispensing, and care pathways for low back and pelvic girdle pain where mechanical stabilization is indicated.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coverage and billing considerations for off-the-shelf sacroiliac orthoses, typical sites of service where the device is provided, and common clinical contexts that prompt use of this orthosis. The publication also summarizes benchmark payment expectations, coding and billing nuances specific to HCPCS Level II code L0621, and relevant policy updates impacting DME suppliers and clinicians. Where specific payer policies or fee schedules are not available in the input, the report notes that data are not available in the input and focuses on general national guidance and clinical context.

Clinical & Coding Specifications
Clinical Context
A 52-year-old ambulatory patient presents to an outpatient orthopedics clinic with chronic unilateral low back and buttock pain localized over the sacroiliac (SI) joint following a twisting injury three months prior. Physical examination demonstrates SI joint tenderness with positive FABER and Gaenslen maneuvers and imaging (pelvic radiographs and MRI) excludes acute fracture but shows degenerative changes at the sacroiliac joint. Conservative care has included activity modification, oral analgesics, and physical therapy with inadequate symptom relief. The clinician prescribes a prefabricated, off-the-shelf sacroiliac orthosis (L0621) to provide pelvic–sacral support and reduce motion about the SI joint.
The clinical workflow: the orthopedist or physical medicine clinician documents the diagnosis and medical necessity, selects an appropriate sized prefabricated SI orthosis (L0621), completes any required DME paperwork, obtains prior authorization if needed from the patient’s payor (e.g., Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, Medicare), fits the device in clinic, provides patient education on wear schedule and skin checks, and documents device delivery, fit, and follow-up plan in the medical record. Typical site of service is outpatient clinic or durable medical equipment supplier with fitting in the clinic or DME shop; the device is off-the-shelf and may be billed as durable medical equipment for home use.
