Corrosion of third degree of right thigh, initial encounter

This code signifies a severe chemical burn, specifically a third-degree corrosion, affecting the right thigh. Third-degree burns involve full-thickness skin destruction, extending into subcutaneous tissue, and are characterized by a white, leathery, or charred appearance with absent sensation. Corrosion indicates the injury was caused by a chemical agent.

This code is appropriate for initial encounters when a patient presents with a deep chemical burn to the right thigh. This would include scenarios such as industrial accidents involving strong acids or bases, or accidental exposure to corrosive household chemicals resulting in full-thickness tissue damage.

• Ensure the documentation clearly specifies "corrosion" (chemical burn) and not a thermal burn.
• Verify the burn depth is explicitly documented as "third degree" or full-thickness.
• Confirm the anatomical site is precisely the "right thigh" and not another lower extremity location.
