Pt had surgery out-of-state for a bone flap replacement. Our rehabilitation doctor received a script from pt's surgeon to remove 69 staples from pt's scalp (no anesthesia was used). Pt is established with our office, but I am puzzled as far as what CPT to code to accurately translate the service that took place. Does our service count as part of the global period for the surgeon out-of-state, is this bundled with an office visit, can I use an unlisted code and attach notes, or do we need to find out the procedure code that took place in the other state and append mod-55? Any insight would be helpful. Thanks!
