As per the provided documentation, the patient only came in for debridement and physician has not performed E&M. So, only debridement code will be coded.
According to provided procedure note, appropriate CPT will be 97597.
Active wound care management involves procedures such as debriding areas of devitalized tissue using a process such as sharp excision, high-pressure waterjet, or non-selective processes such as abrasion or enzyme treatments. According to CPT® guidelines, the intent of these procedures is “to remove devitalized and/or necrotic tissue and promote healing.”
You’ll report these procedures using codes such as the following:
97597 and +97598 (Debridement (eg, high pressure waterjet with/without suction, sharp selective debridement with scissors, scalpel and forceps), open wound, (eg, fibrin, devitalized epidermis and/or dermis, exudate, debris, biofilm), including topical application(s), wound assessment, use of a whirlpool, when performed and instruction(s) for ongoing care, per session, total wound(s) surface area…)
97602 (Removal of devitalized tissue from wound(s), non-selective debridement, without anesthesia (eg, wet-to-moist dressings, enzymatic, abrasion, larval therapy), including topical application(s), wound assessment, and instruction(s) for ongoing care, per session)
