Non-pressure chronic ulcer of abdomen with fat layer exposed

This code describes a persistent, non-healing ulceration on the abdominal wall that is not caused by pressure. The ulcer has progressed to a depth where the subcutaneous fat layer is visible. This indicates significant tissue loss beyond the epidermis and dermis.

Use this code when documentation clearly indicates a chronic, non-pressure ulcer located on the abdomen. The physician's notes must specify that the ulcer has penetrated to the subcutaneous fat layer. This code is appropriate for ulcers resulting from conditions like venous insufficiency, arterial insufficiency, or neuropathic causes, provided pressure is ruled out.

• Ensure the documentation explicitly states "non-pressure" and "abdomen" as the anatomical site.
• Verify the depth of the ulcer is documented as "fat layer exposed" or equivalent (e.g., "subcutaneous tissue visible").
• Always code the underlying cause of the ulcer (e.g., venous insufficiency, diabetes) first, if known and documented.
