Non-prs chr ulcer of buttock with msl invl w/o evd of necr

This code signifies a persistent, non-pressure-related open sore on the buttock that extends into the muscle tissue but does not exhibit signs of tissue death. It indicates a deep ulceration not caused by sustained pressure, such as from immobility.

Apply this code when documentation specifies a chronic ulcer on the buttock, explicitly stating involvement of the muscle layer without any mention of necrosis. This is appropriate for conditions like venous stasis ulcers, arterial ulcers, or diabetic ulcers affecting the buttock, provided they meet the depth and necrosis criteria.

• Ensure documentation clearly differentiates between pressure and non-pressure ulcers.
• Verify the ulcer depth explicitly states "muscle involvement" and absence of necrosis.
• Do not use if any evidence of necrosis (e.g., eschar, gangrene) is present; a different code would be required.
