Summary & Overview
HCPCS Q4051: Splint Supplies, Miscellaneous
HCPCS Level II code Q4051 is used for miscellaneous splint supplies — including thermoplastics, strapping, fasteners, padding, and related expendable materials. It identifies supply items furnished to support splint fabrication, modification, or ongoing splint use. Nationally, accurate coding of splint supplies affects reimbursement for orthotics and rehabilitation services and supports proper capture of non-durable supply costs across care settings.
Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what Q4051 represents, typical sites of service, and the service line context for orthotic and splint supply billing. The publication outlines common modifier patterns (data provided), addresses billing and documentation considerations, and highlights benchmarking and policy topics relevant to payers and provider billing operations. Where specific payer coverage or local policy details are required, readers should consult individual payer guidance. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code Q4051 describes splint supplies, miscellaneous, and includes items such as thermoplastics, strapping, fasteners, padding, and other supplies used to fabricate, modify, or support splints. The code captures expendable materials supplied for splinting rather than the professional fabrication or fitting service.
-
Service type: Durable medical equipment/supplies for orthotic support and splint fabrication
-
Typical site of service: Outpatient clinics, orthotics and prosthetics facilities, rehabilitation centers, and other ambulatory care settings where splints are provided or adjusted
Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents to an outpatient orthotics and prosthetics clinic after sustaining a distal radius fracture with mild displacement and wrist swelling following a fall. The treating clinician evaluates the injury, obtains imaging (radiographs), and determines that immobilization with a custom thermoplastic splint and associated supplies is appropriate. The clinic fabricates a volar wrist splint using thermoplastic material, padding, strapping, fasteners and adhesive padding; supplies used are billed under Q4051 as miscellaneous splint supplies. Typical workflow: patient check-in → clinical evaluation and imaging review → splint prescription and measurement → fabrication and fitting of the splint using thermoplastics, straps, fasteners and padding → patient education on wear, skin checks and follow-up. Typical sites of service include outpatient orthotics/prosthetics clinics, ambulatory surgical centers when used postoperatively, hospital outpatient departments and emergency departments for acute immobilization. Common clinical indications include fractures, acute wrist sprains/ligament injuries, postoperative immobilization after hand/wrist surgery, and protection of soft-tissue repairs.
