Non-prs chronic ulcer of unsp calf limited to brkdwn skin

This code signifies a chronic ulcer on an unspecified calf that is not caused by pressure. The ulceration is superficial, involving only the epidermis and potentially the dermis, without extending into deeper tissues. It indicates a persistent skin breakdown on the lower leg, excluding those due to immobility or sustained pressure.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the calf, and the laterality (right or left) is not specified. This is appropriate for ulcers resulting from venous insufficiency, arterial disease, or neuropathic conditions, provided the depth is limited to skin breakdown. Documentation should clearly state "chronic ulcer," "non-pressure," and "calf."

• Do not use this code if the laterality (right or left calf) is documented; instead, select a more specific code.
• Ensure the documentation explicitly states "non-pressure" to differentiate from pressure ulcers (L89.-).
• Always code the underlying cause of the ulcer (e.g., venous insufficiency, diabetes) as a primary or secondary diagnosis.
