Clinical & Coding Specifications
Clinical Context
A patient presents to an orthopaedic surgery office for follow-up after immobilization of an upper extremity fracture. The patient has a cast placed during the initial emergency or operative encounter and returns for inspection of the casted area due to pain, localized drainage, concern for skin breakdown, or routine wound check beneath the cast. The provider removes a small section of the cast to visualize the underlying wound, assess for pressure areas, check incision sites, or evaluate healing progress. The service is performed in an office setting (POS 11) by an orthopaedic surgeon or orthopaedic trauma/hand specialist, with documentation including indication for cast windowing or partial removal, findings on inspection, any wound care performed, and plan for reapplication or modification of the cast or strapping.
