Summary & Overview
HCPCS L5628: Addition to Lower Extremity, Test Socket, Hemipelvectomy
HCPCS Level II code L5628 denotes an addition to a lower-extremity prosthesis: a test socket for patients following a hemipelvectomy. Nationally, this code captures a specialized prosthetic service used during the fitting and evaluation phase for high-level lower-extremity amputations. Accurate coding for L5628 supports appropriate billing for prosthetic evaluation and trial components and informs utilization tracking for complex limb loss care.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of clinical context and typical sites of service, plus a summary of payer coverage patterns where available. The publication outlines benchmarks and reimbursement context, highlights relevant policy considerations for prosthetic test components, and situates L5628 within related prosthetic coding practice.
This summary is intended to help billing professionals, prosthetists, and policy analysts understand the purpose of L5628, typical clinical scenarios for its use, and what to expect when reviewing payer policies and coverage language for hemipelvectomy test sockets. Data not available in the input will be noted where applicable.
Billing Code Overview
HCPCS Level II code L5628 describes an addition to lower extremity, test socket, hemipelvectomy. This code is used for a prosthetic component added to a lower-extremity prosthesis in the context of a hemipelvectomy amputation, specifically for a test socket intended to evaluate fit, alignment, or comfort prior to fabrication of a definitive socket.
Service Type: Prosthetic test socket addition
Typical Site of Service: Prosthetics and orthotics clinic or specialty rehabilitation facility
Clinical & Coding Specifications
Clinical Context
A 58-year-old male with a right hemipelvectomy stump presents to a prosthetics clinic for fitting of a test socket as part of prosthetic rehabilitation. The patient underwent a surgical hemipelvectomy for oncologic resection six weeks prior and now has a healed distal soft-tissue envelope with residual limb volume fluctuations. The prosthetist performs a clinical evaluation including residual limb inspection, skin integrity assessment, and measurements. A diagnostic casting or digital scan is obtained, and a test socket is fabricated and aligned to evaluate fit, suspension, and gait in the parallel bar and clinic walkway. The workflow includes initial evaluation, socket modification visits to adjust pressure distribution and alignment, a gait training session with the physical therapist, and documentation of functional responses. The L5628 line-item is billed as an addition to lower extremity prosthetic services specific to a hemipelvectomy test socket during the test-fitting phase prior to definitive socket fabrication.
