Corrosion of first degree of right hand, unsp site, sequela

This code signifies a first-degree burn (corrosion) on the right hand, where the specific location on the hand is not documented. It indicates that the burn is an old injury, and the current encounter is for a complication or late effect directly resulting from that past corrosion. First-degree burns typically involve only the epidermis, causing redness and mild pain without blistering.

Apply this code when a patient presents for treatment of a long-term consequence or residual condition stemming from a previously sustained first-degree corrosion to an unspecified site on their right hand. Examples include chronic pain, scarring, or limited range of motion directly attributable to the healed burn. This code is appropriate for follow-up care related to the sequela, not the initial acute injury.

• Always use an additional code to describe the specific nature of the sequela (e.g., scar, contracture, chronic pain).
• Ensure documentation clearly links the current condition to the past first-degree corrosion of the right hand.
• Do not use this code for acute burns; it is exclusively for sequelae.
