Non-prs chr ulcer of left heel and midfoot w fat layer expos

This code signifies a persistent open sore on the left heel or midfoot that is not caused by pressure. The ulceration extends through the epidermis and dermis, exposing the subcutaneous fat tissue. This indicates a moderate depth of tissue loss.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the left heel or midfoot. The medical record must clearly indicate that the ulcer has penetrated to the fat layer. This code is appropriate for ulcers resulting from conditions like peripheral vascular disease, diabetes, or venous insufficiency, provided pressure is ruled out as the primary etiology.

• Ensure the documentation explicitly states "non-pressure" to differentiate from pressure ulcers.
• Verify the anatomical site is specifically the left heel or midfoot; do not use for other foot locations.
• Confirm the depth of the ulcer is documented as "fat layer exposed" or equivalent terminology (e.g., Stage 3 if using pressure ulcer staging for non-pressure ulcers, but only if the etiology is clearly non-pressure).
