Non-pressure chronic ulcer of left calf w fat layer exposed

This code signifies a persistent ulceration on the left calf, not caused by pressure, where the subcutaneous fat tissue is visible. It indicates a deeper wound that has progressed beyond the epidermis and dermis, exposing the adipose layer.

Apply this code when documentation clearly states a chronic, non-pressure ulcer located on the left calf with exposed fat. This typically occurs in patients with underlying conditions like venous insufficiency, peripheral arterial disease, or diabetes, leading to impaired wound healing.

• Ensure documentation specifies "non-pressure" to differentiate from pressure ulcers.
• Verify the laterality (left calf) and the depth of the ulcer (fat layer exposed).
• Always code any associated underlying conditions (e.g., venous insufficiency, diabetes) as additional diagnoses.
