The patient, who is a type 2 diabetic, presents with Fournier’s gangrene. The Alphabetic Index under the main term “diabetes” provides a subentry “with gangrene.” Does this subentry include Fournier’s gangrene? What are the appropriate code assignments for Fournier’s gangrene in a diabetic patient?
No, Fournier’s gangrene is not a type of diabetic gangrene. In this case, there is no documentation of a peripheral angiopathy (circulatory disorder). The Alphabetic Index under diabetes with gangrene leads to code E11.52, Type 2 diabetes mellitus with diabetic peripheral angiopathy with gangrene. Although diabetes may predispose some patients to develop Fournier’s gangrene, this is not a diabetic gangrene nor a peripheral angiopathy, which progresses more slowly and occurs secondary to circulatory issues. Fournier’s is a bacterial necrotizing soft tissue infection, which can occur due to trauma, postoperative complications, or other causes.
