Non-prs chr ulcer of abd with muscle invl w/o evd of necr

This code signifies a persistent, non-healing open sore on the abdominal wall that extends into the muscle tissue but does not show signs of dead tissue. This type of ulcer is not caused by pressure and indicates a deeper level of tissue damage.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the abdomen with involvement of the underlying muscle layer. The physician's notes must explicitly state the absence of necrosis. This code is appropriate for ulcers resulting from conditions like venous insufficiency, arterial insufficiency, or neuropathic causes, provided they are not pressure-related.

• Ensure documentation clearly differentiates between "muscle involvement" and "bone involvement" or "necrosis."
• Always review for laterality if specified, though this particular code does not include laterality.
• Confirm the ulcer is explicitly stated as "non-pressure" to avoid miscoding with pressure ulcers.
