Non-prs chr ulcer oth prt unsp low leg lmt to brkdwn skin

This code signifies a chronic ulcer on the lower leg, excluding the ankle or foot, that is not caused by pressure. The ulcer's severity is limited to the epidermis and/or dermis, indicating only superficial tissue loss.

Use this code for documentation describing a non-healing ulcer on the lower leg (e.g., calf, shin) where the etiology is not pressure-related (e.g., venous, arterial, neuropathic, traumatic). The medical record must clearly state that the ulceration is confined to the skin layers.

• Ensure documentation specifies "unspecified lower leg" and "limited to breakdown of skin" to support this code.
• Distinguish from pressure ulcers (L89.-) and ulcers of the ankle/foot (L97.3-L97.5).
• Always code the underlying cause of the ulcer (e.g., chronic venous insufficiency) as a primary or secondary diagnosis.
