Non-pressure chronic ulcer of face with necrosis of muscle

This code signifies a long-standing ulcer on the face that is not caused by pressure, and where the tissue death (necrosis) has extended into the muscle layer. It indicates a severe, deep tissue injury affecting the facial musculature.

Apply this code when documentation clearly states a chronic, non-pressure ulcer located on the face with confirmed muscle involvement due to necrosis. This typically occurs in patients with underlying conditions affecting wound healing, such as vascular disease or diabetes, where the ulcer has progressed to a significant depth.

• Ensure the documentation specifies "non-pressure" and "chronic" to differentiate from acute or pressure-related ulcers.
• Verify the anatomical site is explicitly "face" and that necrosis extends to the "muscle" layer.
• Do not confuse with codes for ulcers involving only skin or subcutaneous tissue; the key is muscle involvement.
