Corrosion of second degree of right hand, unsp site, subs

This code signifies a second-degree chemical burn (corrosion) affecting the right hand. It indicates that the patient is presenting for follow-up care or treatment of the injury after the initial encounter. The specific site on the hand is not further detailed.

Use this code for patients returning for ongoing management of a right hand, second-degree chemical burn. This includes wound care, re-evaluation, or treatment of complications during the healing phase. It is appropriate after the initial diagnosis and treatment have been rendered.

• Ensure the documentation clearly specifies "right hand" and "second degree" corrosion.
• Verify that the encounter is for subsequent care, not the initial treatment of the burn.
• Confirm the etiology is corrosion (chemical burn) rather than a thermal burn.
