Burn of 3rd deg mu sites of unsp ankle and foot, sequela

This code signifies a healed third-degree burn affecting multiple areas of the ankle and foot, where the specific ankle or foot (left or right) is not documented. It indicates that the patient is experiencing a long-term complication or residual effect directly resulting from the original severe burn injury.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a previously sustained third-degree burn to multiple, unspecified sites of the ankle and foot. This applies to follow-up encounters for scar contractures, chronic pain, or functional limitations stemming from the original injury.

• Always ensure documentation clearly links the current condition to the past burn injury.
• Confirm that the burn was full-thickness (third-degree) and involved more than one site on the ankle/foot.
• Only use the "S" seventh character for sequelae when the acute phase of the burn has passed and the patient is being treated for the residual effects.
