Non-prs chr ulc unsp prt of l low leg w fat layer exposed

This code signifies a persistent open sore on the left lower leg that is not caused by pressure, where the subcutaneous fat tissue is visible. It indicates a deep ulceration extending beyond the dermis into the adipose layer, without specifying the exact anatomical location on the lower leg.

Use this code when documentation clearly states a chronic, non-pressure ulcer on the left lower leg with exposed fat, and the specific site (e.g., ankle, calf) is not identified. This code is appropriate for ulcers due to venous insufficiency, arterial disease, or neuropathic causes, provided the depth reaches the fat layer.

• Ensure documentation specifies "non-pressure" to differentiate from pressure ulcers (L89.-).
• Verify the laterality (left leg) and the depth of the ulcer (fat layer exposed).
• If the specific anatomical site on the left lower leg is documented (e.g., calf, ankle), a more specific code within the L97.92- series should be used.
