Corros first degree of unsp mult fngr, inc thumb, sqla

This code describes a first-degree chemical burn (corrosion) affecting multiple fingers, including the thumb, where the specific finger(s) involved are not documented. The injury has healed, and this code is used to report a late effect or complication of that original burn.

Use this code when documenting a long-term consequence or residual condition resulting from a first-degree chemical burn to multiple, unspecified fingers, including the thumb. This applies when the acute phase of the injury has passed, and the patient is presenting for treatment of a sequela.

• Always use this "S" (sequela) extension for conditions that are late effects of an injury.
• Ensure documentation clearly states the burn was chemical (corrosion) and involved multiple, unspecified fingers, including the thumb.
• Do not use this code for acute burns; instead, refer to the appropriate acute corrosion code.
