Corros unsp degree of single r finger except thumb, sqla

This code signifies a long-term complication or late effect resulting from a chemical burn to a single finger on the right hand, excluding the thumb. The original injury's severity is not specified, and the sequela could manifest as scarring, chronic pain, or functional impairment.

Apply this code when documenting a current condition that is a direct consequence of a past corrosive injury to a right finger (not the thumb). This is appropriate for follow-up visits addressing residual issues from the initial chemical burn, even if the original injury has healed.

• Always assign an additional code to specify the nature of the sequela (e.g., scar, contracture).
• Ensure the documentation clearly links the current condition to a previous corrosive burn of a right finger.
• This code is for sequelae only; do not use it for acute corrosive injuries.
