Corros 2nd deg mul right fingers (nail), inc thumb, sequela

This code indicates a second-degree chemical burn (corrosion) affecting multiple fingers, including the thumb, on the patient's right hand. The injury specifically involves the nail or nail bed. The "S" seventh character signifies that this encounter is for the sequelae (late effects) of the original injury, meaning the acute phase has passed, and the patient is being treated for residual problems.

Use this code when documenting treatment for long-term complications or residual effects stemming from a second-degree chemical burn to the right hand's multiple fingers and thumb, specifically impacting the nail. This could include ongoing pain, scarring, nail deformity, or functional limitations directly attributable to the original corrosion. It is appropriate for follow-up visits after the initial healing of the acute injury.

• Ensure documentation clearly specifies "sequela" or "late effect" and links the current condition to the past corrosion.
• Verify the burn was chemical (corrosion) and not thermal (burn) to differentiate from T23.241S.
• Confirm the involvement of multiple fingers, including the thumb, on the right hand, and that the nail is affected.
