Burn of third degree of chin, sequela

This code signifies a full-thickness burn injury to the chin, where the damage extends through all layers of the skin and potentially into underlying tissues. The "sequela" designation indicates that this code is used for the late effects or complications of the original burn, after the acute phase of healing has passed. These sequelae could include scarring, contractures, or chronic pain.

Apply this code when documenting the long-term consequences of a third-degree burn to the chin. This is appropriate for follow-up visits, rehabilitation, or when managing chronic issues directly resulting from the initial severe burn. Do not use this code for the initial acute burn injury.

• Always ensure documentation clearly states "third degree" and specifies the "chin" as the anatomical site.
• The "S" in the seventh character indicates sequela; verify that the patient is being treated for a late effect, not an active burn.
• Consider additional codes for specific sequelae, such as hypertrophic scarring (L91.0) or contracture of skin (L90.5), if documented.
