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

This code signifies a second-degree chemical burn, also known as corrosion, affecting multiple unspecified fingers, including the thumb. The "sequela" designation indicates that this code is used for complications or conditions arising directly from the original burn injury, after the acute phase has passed.

This code is appropriate for documenting long-term effects or complications of a second-degree chemical burn to multiple fingers and the thumb. Examples include chronic pain, scarring, contractures, or functional limitations that persist after the initial healing of the burn. It should be used when the patient is no longer receiving active treatment for the acute burn.

• Always ensure the documentation clearly specifies "sequela" or a chronic condition resulting from the burn.
• Verify that the burn was indeed a second-degree corrosion and involved multiple fingers, including the thumb.
• Do not use this code for acute burn treatment; instead, use the appropriate acute burn code with the 7th character for initial encounter (A), subsequent encounter (D), or active treatment.
