Clinical & Coding Specifications
Clinical Context
A 6-year-old child presents to a pediatric urgent care clinic after falling from playground equipment and sustaining a distal forearm fracture. After clinical evaluation and plain radiographs confirm a non-displaced distal radius fracture, the orthopedic clinician determines that immobilization with a short arm fiberglass cast is appropriate. The patient is accompanied by a parent; consent is obtained for casting and cast care instructions are provided. The clinician or cast technician sizes and applies the pediatric short arm fiberglass cast, trims edges, and provides written home care instructions, including activity restrictions and follow-up with pediatric orthopedics for repeat radiographs in 1–2 weeks. The typical site of service is an outpatient clinic, urgent care center, or hospital outpatient department where pediatric casting supplies and trained personnel are available. Typical patient workflow includes triage, evaluation by clinician, radiography, treatment decision, casting application using supplies associated with Q4012, and scheduling of follow-up. Documentation includes diagnosis, site of fracture, consent, materials used (short arm pediatric fiberglass cast supplies), time of application, and follow-up plan.
