Non-pressure chronic ulcer of groin with necrosis of muscle

This code represents a persistent, non-healing open sore located in the groin region that is not caused by pressure. The ulceration extends into and involves the muscle tissue, indicating significant tissue death (necrosis) at this deep level. It signifies a severe stage of a chronic ulcer.

Apply this code when documentation clearly states a non-pressure chronic ulcer in the groin area with confirmed necrosis extending to the muscle. This typically occurs in patients with underlying conditions like diabetes, peripheral vascular disease, or venous insufficiency. Documentation should specify the anatomical site (groin) and the depth of tissue involvement (muscle necrosis).

• Differentiate from pressure ulcers; this code is specifically for non-pressure etiology.
• Ensure documentation explicitly states "necrosis of muscle" to support this specific code.
• Code also any underlying systemic conditions contributing to the ulcer formation (e.g., E11.621 for diabetic foot ulcer with necrosis).
