Question: We are providing wound care and IV antibiotic administration for a post-operative abdominal wound infection due to Staph aureus. How should I code? -- Vermont Subscriber Answer: For this patient, list: • 998.59 (Other postoperative infection); • 041.11 (Staphylococcus aureus); and • V58.81 (Fitting and adjustment of vascular catheter). Don't report a surgical dressing V code for this wound because it's a complicated wound. If the Staph aureus is methicillin-resistant, follow the 041.11 code with V09.0 (Infection with microorganisms resistant to penicillins).
