Non-prs chronic ulcer oth prt r low leg w fat layer exposed

This code signifies a persistent, non-pressure-related open sore on the right lower leg that has eroded through the epidermis and dermis, exposing the subcutaneous fat layer. This type of ulcer is typically slow to heal and may be associated with underlying conditions like venous insufficiency, arterial disease, or diabetes.

Apply this code when documentation clearly indicates a chronic ulcer on the right lower leg, explicitly stating it is not pressure-related and that the wound depth extends to the fat layer. This is appropriate for ulcers resulting from conditions other than sustained pressure, such as stasis ulcers or neuropathic ulcers.

• Ensure documentation specifies "right lower leg" and "fat layer exposed" to support this specific code.
• Distinguish carefully from pressure ulcers (L89.-) and ulcers of unspecified depth or with muscle/bone exposure.
• Always code the underlying cause of the ulcer (e.g., venous insufficiency I87.2-, diabetes E11.621) as a primary or secondary diagnosis.
