Clinical & Coding Specifications
Clinical Context
A 6-year-old child presents to a pediatric orthopedic clinic after falling from playground equipment and sustaining a distal forearm fracture. Radiographs confirm a nondisplaced both-bone forearm fracture requiring immobilization. The patient is placed under topical or minimal sedation; a long arm pediatric fiberglass cast is applied to immobilize the elbow and forearm, extending from the proximal humerus to the metacarpal heads. The procedure is performed in an ambulatory clinic or emergency department setting. Documentation includes indication, consent, limb laterality, materials used (fiberglass), cast type (long arm cast), patient age (pediatric 0–10 years), time of application, and any complications or additional procedures (e.g., closed reduction) documented with appropriate CPT/ICD-10 linkage. Typical workflow: triage and assessment → radiography → reduction if required → cast application with padding and fiberglass splinting layers → post-application neurovascular check and discharge instructions. Follow-up is scheduled for cast check and radiographic healing assessment.
