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

This code signifies a persistent, open sore on an unspecified area of the lower leg, excluding the foot and ankle, that is not caused by pressure. The ulceration extends to involve the bone, but there is no indication of dead tissue (necrosis) within the wound. This condition often arises from underlying vascular insufficiency, diabetes, or other systemic diseases.

Apply this code when documentation clearly indicates a chronic, non-pressure ulcer on the lower leg (e.g., shin, calf) with confirmed bone involvement, and the specific location on the lower leg is not specified. The medical record must explicitly state the absence of necrosis. This code is appropriate for ulcers that have been present for an extended period and are resistant to healing.

• Ensure documentation specifies "bone involvement" and explicitly states "without evidence of necrosis."
• Do not use this code if the ulcer is due to pressure; refer to L89 codes.
• Always sequence this code after the underlying cause of the ulcer (e.g., diabetes mellitus with complications, peripheral vascular disease).
