Non-prs chr ulc skin/ oth site with msl invl w/o evd of necr

This code signifies a persistent skin ulcer, not caused by pressure, located on an anatomical site other than those specifically categorized (e.g., lower limb, sacrum). The ulceration extends into the muscle tissue, but there is no documented evidence of tissue death or necrosis within the wound.

Apply this code when documentation clearly indicates a chronic, non-pressure ulcer affecting muscle tissue at an unspecified or "other" body site. This typically applies to ulcers on the trunk, head, or upper extremities that are not due to decubitus. Supporting documentation should specify the depth of the ulceration reaching muscle and explicitly state the absence of necrosis.

• Ensure the documentation explicitly states "without evidence of necrosis" to differentiate from codes indicating necrosis.
• Verify the ulcer is not pressure-related; if it is, a pressure ulcer code (L89.-) should be used.
• Confirm the anatomical location is not covered by more specific non-pressure ulcer codes (e.g., L97.- for lower extremity).
