Non-prs chr ulc oth prt unsp lw leg w msl invl w/o evd necr

This code signifies a persistent, non-pressure-related open sore on an unspecified area of the lower leg, extending into the muscle tissue. The ulcer shows no signs of dead tissue (necrosis). This indicates a deep wound that has penetrated beyond the subcutaneous layer.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the lower leg with involvement of muscle, but explicitly notes the absence of necrosis. This is appropriate for ulcers caused by conditions like venous insufficiency, arterial disease, or neuropathic factors, where the specific location on the lower leg is not further specified.

• Ensure documentation specifies "non-pressure" and "muscle involvement without necrosis."
• Do not use if the ulcer is due to pressure, or if necrosis is present; separate codes exist for those scenarios.
• Always seek more specific anatomical location documentation (e.g., calf, ankle) if available to use a more precise code.
