Corrosion of second degree of right ankle and foot, sequela

This code indicates a second-degree corrosion injury affecting the right ankle and/or foot, where the acute phase of the injury has resolved, and the patient is now experiencing residual effects or complications. Second-degree corrosions involve damage to the epidermis and dermis, often presenting with blistering, pain, and swelling.

Use this code when documenting the long-term consequences or late effects of a chemical burn to the right ankle or foot that was initially classified as second-degree. This applies to situations such as scar formation, chronic pain, contractures, or other persistent issues directly resulting from the original corrosion. It should not be used for the initial acute injury.

• Always assign an additional code to describe the specific sequela (e.g., scar, contracture).
• Ensure the documentation clearly indicates the injury is a corrosion (chemical burn) and not a thermal burn.
• Verify that the laterality (right) and body site (ankle and foot) are accurately reflected in the medical record.
