Non-pressure chronic ulcer of buttock limited to brkdwn skin

This code describes a chronic ulcer on the buttock that is not caused by pressure, and its severity is limited to the epidermal and dermal layers. It indicates a superficial skin breakdown without involvement of subcutaneous tissue, muscle, or bone.

Use this code for documented non-pressure ulcers of the buttock where the physician explicitly states the ulcer is superficial, involving only the skin. This typically applies to ulcers resulting from conditions like venous insufficiency, arterial insufficiency, or neuropathic causes, but not from sustained pressure. Documentation should clearly specify the location and the limited depth of tissue involvement.

• Differentiate carefully from pressure ulcers (L89.-) and other types of skin breakdown.
• Ensure documentation specifies "non-pressure" and "limited to breakdown of skin" or similar superficial description.
• Do not use if the ulcer extends into subcutaneous tissue, muscle, or bone; a more specific code indicating greater depth would be required.
