Non-pressure chronic ulcer of unsp ankle w fat layer exposed

This code signifies a persistent open sore on an unspecified ankle that is not caused by pressure, and where the subcutaneous fat tissue is visible. It indicates a full-thickness skin loss extending into the adipose layer, without specifying laterality.

Use this code when documentation clearly states a chronic, non-pressure ulcer on the ankle with exposed fat, and the specific ankle (left or right) is not identified. This typically applies to ulcers that have been present for an extended period and show no signs of healing.

• Ensure the documentation explicitly states "non-pressure" to differentiate from pressure ulcers.
• Confirm the ulcer depth reaches the fat layer; if bone or muscle is exposed, a different code is required.
• If laterality (left or right ankle) is documented, a more specific code should be chosen.
