Non-pressure chronic ulcer of chest with fat layer exposed

This code signifies a persistent, non-pressure-related open sore on the chest wall where the subcutaneous fat tissue is visible. It indicates a significant tissue loss extending beyond the epidermis and dermis, exposing the adipose layer.

Apply this code when documentation clearly states a chronic ulcer on the chest, explicitly noting the involvement and exposure of the fat layer. This typically arises from conditions like venous insufficiency, arterial disease, neuropathic causes, or other non-pressure etiologies, and not from prolonged pressure.

• Ensure documentation specifies "chronic" and "non-pressure" to differentiate from acute ulcers or pressure ulcers.
• Verify that the physician's notes explicitly state "fat layer exposed" or describe the depth as extending into the subcutaneous tissue.
• Always code the underlying cause of the ulcer (e.g., venous insufficiency, diabetes) as an additional diagnosis.
