Burn of third degree of unspecified ankle, sequela

This code signifies a third-degree burn affecting an unspecified ankle, where the acute injury has healed, and the code is used to report a late effect or complication of that burn. Third-degree burns involve full-thickness destruction of the skin, often extending into subcutaneous tissue, and typically result in significant scarring, contractures, or other long-term sequelae.

Apply this code when documenting a patient presenting with a chronic condition or complication directly resulting from a previously sustained third-degree burn to an ankle. Examples include scar contractures limiting ankle mobility, chronic pain, or non-healing ulcers at the burn site, long after the initial burn has healed. This code is not for the initial treatment of an acute burn.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., scar contracture, chronic ulcer).
• Ensure documentation clearly links the current condition to the previous third-degree ankle burn.
• Verify that the burn is indeed of the third degree and that the affected area is the ankle, with no further specification of laterality.
