Corrosion of third degree of chin, subsequent encounter

This code signifies a severe, full-thickness burn injury to the chin, characterized by destruction of all skin layers, including subcutaneous tissue, and potentially muscle or bone. It indicates that the patient is receiving follow-up care for this specific injury after the initial treatment phase.

Apply this code when documenting subsequent encounters for a patient with a third-degree corrosion of the chin. This includes visits for wound care, debridement, skin grafting, infection management, or other ongoing treatment related to the initial severe burn.

• Ensure documentation clearly specifies "third degree" and "chin" for accurate code assignment.
• Verify the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Always review the medical record for any associated complications or additional injuries that may require separate coding.
