Non-prs chronic ulcer of right thigh w necrosis of muscle

This code signifies a persistent, non-pressure-related open sore located on the right thigh, characterized by the presence of dead muscle tissue. This indicates a severe stage of ulceration, extending beyond the skin and subcutaneous layers into the underlying muscle.

Use this code when documentation clearly indicates a chronic ulcer on the patient's right thigh that is not caused by pressure, and specifically notes necrosis (tissue death) affecting the muscle layer. This typically applies to ulcers resulting from conditions like peripheral vascular disease, diabetes, or venous insufficiency, where the tissue damage is extensive.

• Ensure documentation explicitly states "non-pressure" and specifies "right thigh" and "necrosis of muscle."
• Do not use this code for pressure ulcers; refer to the L89 category for those.
• Always sequence this code after any underlying systemic condition (e.g., E11.621 for diabetic ulcer) that caused the ulcer, if applicable.
