Corrosion of second degree of unspecified axilla, sequela

This code signifies a healed or residual condition resulting from a second-degree corrosion (chemical burn) affecting an unspecified axilla. It indicates that the acute phase of the injury has passed, and the patient is now experiencing long-term effects such as scarring, contracture, or chronic pain directly attributable to the original chemical burn.

Apply this code when documenting follow-up care for a patient who previously sustained a second-degree chemical burn to the axilla and is now presenting with a sequela. This includes scenarios where the patient is being treated for complications like scar tissue management, limited range of motion, or persistent nerve damage stemming from the original injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the previous second-degree axillary corrosion.
• Avoid using this code for acute or active corrosion injuries; those require codes from the T22.2 or T22.3 series.
