Corrosion of third degree of forehead and cheek, subs encntr

This code signifies a severe chemical burn, specifically a third-degree corrosion, affecting the forehead and cheek. Third-degree burns involve full-thickness skin destruction, extending through the epidermis and dermis, and potentially into subcutaneous tissue, muscle, or bone.

Apply this code for follow-up care, healing, or treatment of complications arising from a third-degree chemical burn to the forehead and cheek. This includes subsequent hospital visits, wound care, or management of long-term sequelae after the initial acute phase of injury.

• Requires an external cause code to identify the corrosive agent.
• Confirm the encounter type is "subsequent" (D) and not "initial" (A) or "sequela" (S).
• Ensure documentation clearly specifies "corrosion" (chemical burn) and not a thermal burn.
