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

This code signifies a chronic ulcer on an unspecified ankle that is not caused by pressure. The ulcer's severity is limited to the epidermis and dermis, indicating only superficial skin breakdown without involvement of deeper tissues like subcutaneous fat, muscle, or bone.

Apply this code when documentation specifies a non-pressure chronic ulcer located on either the right or left ankle, and the deepest extent of tissue loss is confined to the skin. This is appropriate when the specific ankle (left or right) is not documented, or when the provider explicitly states "unspecified ankle."

• Ensure documentation clearly states the ulcer is non-pressure and chronic.
• Verify the depth of the ulcer is limited to "breakdown of skin" or superficial, without mention of deeper tissue involvement.
• If the specific ankle (right or left) is documented, use the more specific L97.31- or L97.32- codes.
