Corrosion of 2nd deg mul sites of unsp wrs/hnd, sequela

This code signifies a healed or residual effect from a second-degree corrosion (chemical burn) that affected multiple sites on an unspecified wrist and hand. The original injury has resolved, but there are lasting consequences such as scarring, contractures, or chronic pain.

Apply this code when documenting a patient presenting with a current condition that is a direct result of a previously sustained second-degree chemical burn to multiple areas of the wrist and hand. This code is appropriate for follow-up encounters after the acute phase of the injury has passed and the sequelae are being treated or evaluated.

• Always use a seventh character "S" for sequela when the acute injury has healed and the patient is being treated for the residual effects.
• Ensure documentation clearly links the current condition to the past chemical burn of the wrist and hand.
• Do not use this code for acute or active second-degree chemical burns; those would require an acute seventh character.
