Secondary wound closure
A patient presented with a past history of an open reduction internal fixation for a medial tibial plateau fracture seven years prior. Approximately six weeks ago, she presented for incision and drainage (I&D) with debridement/excision and washout of the right knee due to septic pre-patellar and pre-infrapatellar bursitis. Following the procedure, a wound VAC was placed on the right anterior knee. The patient now presents for secondary closure of the I&D wound and re-application of a wound VAC. There was a 2.5 cm wide x 5.0 cm long I&D wound that was shallow and covered with granulation tissue over the anterior aspect of the right knee. A knife was utilized to undermine the skin and subcutaneous tissue margins of the wound for a distance of approximately 2-3 cm. The margins of the wound were freshened by sharp dissection and the skin and subcutaneous tissue edges were approximated with sutures. Would this procedure be coded as a simple secondary/delayed closure with CPT code 12020 or a delayed intermediate closure and reported with CPT code 17999 ? ...

Article Overview
This article reviews a wound-care coding question arising after prior orthopedic surgery and a later incision and drainage procedure with debridement and wound VAC placement. It focuses on how the postoperative closure encounter is characterized for coding purposes and is aimed at coders and billing professionals working with surgical, wound, and orthopedic cases. The discussion centers on the clinical context, the type of closure performed, and whether the encounter fits a straightforward secondary or delayed closure approach.
Why This Topic Matters
Wound closure coding can vary based on the operative history, tissue handling, and the nature of the return procedure. Understanding how this scenario is analyzed helps coders avoid misclassification of postoperative wound management services.
