Corrosion of third degree of unsp hand, unsp site, sequela

This code signifies a third-degree chemical burn, or corrosion, affecting an unspecified area of an unspecified hand, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication. This could include scarring, contractures, or chronic pain resulting from the original severe chemical exposure.

Apply this code when documenting a patient encounter for a long-term consequence of a third-degree chemical burn to the hand, where the specific hand (left or right) and the precise location on the hand are not documented. This code is appropriate for follow-up care related to the sequelae, not the initial acute injury.

• Always strive for greater specificity regarding the hand (left/right) and site if documented in the medical record.
• This code requires an additional code to describe the specific nature of the sequela (e.g., scar, contracture).
• Do not use for initial or active treatment of the acute corrosion; this code is exclusively for late effects.
