In simple words: This code covers the materials used to create a lightweight, durable cast for a child's broken or injured leg, from the thigh to the ankle, but not including the foot.

This code represents the supplies for a fiberglass long leg cylinder cast specifically for children aged 10 and younger. The cast immobilizes the leg from the upper thigh to the ankle, excluding the foot. It is used for knee fractures, dislocations, soft tissue injuries, post-operative immobilization, and correcting deformities. Fiberglass casts are preferred for their lighter weight, durability, and heat resistance compared to plaster casts.

Example 1: A 9-year-old child sustains a fracture in their femur near the knee joint. A fiberglass long leg cylinder cast (Q4036) is applied to stabilize the fracture and allow for healing., A 6-year-old child with a severe knee sprain requires immobilization. The physician applies a fiberglass long leg cylinder cast (Q4036) to restrict movement and promote healing of the soft tissues., Following knee surgery on an 8-year-old child, a fiberglass long leg cylinder cast (Q4036) is used to immobilize the knee joint and protect the surgical site during the initial healing phase.

Documentation should include the diagnosis requiring the cast, the date of application, the type of cast (fiberglass long leg cylinder), and the patient's age, confirming they are 10 years old or younger. The medical record must also detail the condition being treated (fracture, dislocation, soft tissue injury, post-operative immobilization, or deformity correction).

** This code was intended for use by practitioners and suppliers for reporting cast supplies when billing Medicare. It was among several temporary Q codes introduced for cast and splint supplies. Please refer to the current HCPCS Level II code set for valid codes and updated guidelines.
