Non-prs chr ulc oth prt unsp ft w msl invl w/o evd of necr

This code signifies a chronic, non-pressure-related ulcer located on an unspecified part of the foot, extending into the muscle layer. It indicates the absence of necrotic tissue within the ulcer bed. This condition often arises from underlying vascular insufficiency, neuropathy, or other systemic diseases.

Use this code when documentation specifies a chronic foot ulcer (not caused by pressure) that involves muscle tissue, but explicitly states no necrosis is present. This is appropriate for ulcers where the exact location on the foot is not specified, such as "foot ulcer" without further anatomical detail. Documentation should clearly indicate the depth of tissue involvement and the absence of necrotic tissue.

• Ensure documentation specifies "chronic" and "non-pressure" to differentiate from acute or pressure ulcers.
• Verify the depth of involvement explicitly states "muscle" and confirms the absence of necrosis.
• Avoid using this code if a more specific anatomical location on the foot (e.g., heel, malleolus) is documented; use a more precise L97.5- subcategory.
