Recognize How to Code This Rapidly Spreading Infection
Question: A 63-year-old patient presented to the emergency department (ED) with severe perineal pain and systemic toxicity. The patient had experienced rapidly progressing perineal/scrotal pain, swelling, and skin discoloration over 24 hours accompanied by a fever, tachycardia, and disproportionate pain. A provider performed emergency surgical debridement of the skin, subcutaneous tissue, and fascia of the external genitalia and perineum for necrotizing soft tissue infection. The findings were documented as extensive necrotizing fasciitis of the perineum and fascial necrosis. What codes will I use to report this encounter? Mississippi Subscriber Answer: Assign 11004 (Debridement of skin, subcutaneous tissue, muscle and fascia for necrotizing soft tissue infection; external genitalia and perineum) to report the surgical debridement of the skin, subcutaneous tissue, and fascia. Next, you’ll use N49.3 (Fournier gangrene) to report the evolving necrosis of the patient’s perineum and scrotum. Fournier gangrene is a type of tissue-destroying infection that specifically impacts the genital and perineal areas. Then, you’ll assign M72.6 (Necrotizing fasciitis) to report the extensive necrotizing fasciitis of the perineum. Mike Shaughnessy, BA, CPC, Production Editor, AAPC
