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

This code signifies a third-degree chemical burn (corrosion) affecting multiple fingers, including the thumb, where the specific fingers involved are not documented. A third-degree burn involves full-thickness destruction of the skin and underlying tissue. The "S" seventh character indicates that this code is for a sequela, meaning it's used to report a late effect or complication of the original injury.

Use this code when documenting a long-term complication or residual condition resulting from a past third-degree chemical burn to multiple, unspecified fingers, including the thumb. This could include scarring, contractures, chronic pain, or functional impairment that is a direct consequence of the initial corrosion. It is appropriate when the acute phase of the injury has passed.

• Always sequence this sequela code after the code for the specific late effect or complication being treated.
• Ensure documentation clearly links the current condition to a past third-degree chemical burn of the fingers.
• Verify that the burn involved multiple fingers, including the thumb, and that the specific digits are not specified in the medical record.
