HCPCS Q4036: Pediatric Long Leg Cylinder Fiberglass Cast Supplies
HCPCS Level II code Q4036 designates pediatric long leg cylinder cast supplies made of fiberglass for patients aged 0–10 years. This supply-level code identifies materials used when applying a fiberglass long leg cylinder cast, an essential component of non-operative immobilization for pediatric lower-extremity fractures and certain soft-tissue injuries. Accurate use of the code supports inventory tracking, supply reimbursement, and consistent documentation of casting materials.
Key payers in national analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for pediatric fiberglass long leg casting, typical sites of service where the supply is used (outpatient clinics, emergency departments, ambulatory surgical centers, and inpatient hospitals), and the payers commonly involved in covering these supplies. The publication also summarizes common modifiers and operational considerations when billing supply codes and points to benchmarks and policy updates relevant to durable medical supplies.

Clinical & Coding Specifications
Clinical Context
A 7-year-old child presents to the urgent care clinic after falling from playground equipment and sustaining a displaced tibial shaft fracture. Examination shows swelling and deformity of the lower leg; neurovascular status is intact. Radiographs confirm a midshaft tibial fracture without open wounds. The orthopedic technician and pediatric orthopedic clinician apply a Q4036 long leg cylinder fiberglass cast (pediatric 0-10 years) to immobilize the tibia and knee in a neutral position. The clinical workflow includes triage and history, radiographic imaging, fracture reduction if needed, cast application using pediatric-sized fiberglass materials, documentation of cast type/size and skin protection, patient/caregiver education regarding cast care and signs of complication, and scheduling follow-up visit for repeat radiographs and cast removal or modification. Typical sites of service are outpatient orthopedic clinics, urgent care centers, emergency departments, and ambulatory surgery centers where pediatric casting supplies are stocked.
