Corrosion of third degree of right axilla, sequela

This code signifies a healed or chronic complication resulting from a third-degree chemical burn to the right armpit. A third-degree burn involves full-thickness skin destruction, and a sequela indicates a long-term effect such as scarring, contracture, or chronic pain that persists after the initial injury has resolved.

Use this code when documenting a patient presenting with a lasting consequence of a past third-degree chemical burn affecting their right axilla. This applies to follow-up encounters where the primary reason for the visit is to address or manage these chronic issues, rather than the acute burn itself.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a previous third-degree chemical burn of the right axilla.
• Verify the burn was chemical in nature and not thermal or electrical, as different codes apply.
