Non-prs chr ulc unsp prt l lw leg w bne invl w/o evd of necr

This code signifies a persistent, non-pressure-related ulcer located on an unspecified area of the left lower leg. The ulcer has progressed to involve the underlying bone, but there is no indication of tissue death (necrosis) within the ulcer or surrounding area.

This code is appropriate when documentation specifies a chronic ulcer on the left lower leg that is not caused by pressure, and imaging or surgical findings confirm bone involvement without evidence of necrosis. It applies to conditions like venous stasis ulcers, arterial ulcers, or diabetic ulcers that have eroded to the bone.

• Ensure documentation clearly states "non-pressure" and specifies "left lower leg."
• Confirm bone involvement is explicitly documented, often through imaging reports (e.g., X-ray, MRI) or operative notes.
• Verify the absence of necrosis; if necrosis is present, a different code from the L97 series would be more appropriate.
