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

This code signifies a long-standing ulcer on the right lower leg, not caused by pressure, that has progressed to involve the underlying bone. There is no evidence of tissue death (necrosis) associated with the ulceration. The specific anatomical location of the ulcer on the lower leg is not documented.

Use this code for patients presenting with a chronic, non-pressure ulcer on the right lower leg where imaging or surgical findings confirm bone involvement. Documentation should clearly state "chronic ulcer," "non-pressure," and "bone involvement," while explicitly ruling out necrosis. This code is appropriate when the exact site on the lower leg (e.g., calf, ankle) is not specified in the medical record.

• Ensure documentation explicitly states "non-pressure" to differentiate from pressure ulcers (L89.-).
• Confirm bone involvement through imaging reports (e.g., X-ray, MRI) or operative notes.
• Do not use if necrosis is present; a different subcategory would apply.
