Corrosion of third degree of right hand, unsp site, sequela

This code signifies a third-degree corrosive injury (e.g., chemical burn) to an unspecified area of the right hand, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly resulting from the original corrosion. These sequelae can include scarring, contractures, chronic pain, or functional impairment.

Use this code when documenting follow-up care for a patient who previously sustained a third-degree chemical burn to their right hand, and the current encounter addresses a long-term consequence of that injury. This applies to situations where the initial burn has resolved, but its lasting effects require ongoing medical attention.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to the previous third-degree corrosion of the right hand.
• Avoid using this code for acute corrosive injuries; those require codes from the T20-T25 range without the "S" seventh character.
