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

This code signifies a persistent open sore on the left ankle that is not caused by pressure. The ulceration is superficial, affecting only the epidermis and dermis, without extending into deeper tissues like muscle or bone. It indicates a chronic wound that has failed to heal within an expected timeframe.

Apply this code when documentation specifies a non-pressure chronic ulcer located on the left ankle, with the depth explicitly stated as limited to skin breakdown. This is appropriate for conditions such as venous stasis ulcers, arterial ulcers, or neuropathic ulcers on the ankle, provided pressure is ruled out as the etiology and the ulcer does not penetrate beyond the skin.

• Ensure documentation clearly specifies "left ankle" and "non-pressure" etiology.
• Verify the depth of the ulcer is explicitly stated as "skin breakdown" or superficial; do not use for ulcers extending to subcutaneous tissue or deeper.
• Always code the underlying cause of the ulcer (e.g., chronic venous insufficiency, atherosclerosis) first, followed by this code.
