Corrosion of first degree of unspecified upper arm, sequela

This code signifies a first-degree burn, specifically corrosion, affecting an unspecified area of the upper arm. It indicates a superficial injury caused by a chemical agent, characterized by redness and mild pain, without blistering or skin breakdown. The "sequela" designation means this code is used for complications or conditions arising as a direct result of a previously treated or resolved injury.

Apply this code when documenting a current problem or complication stemming from a past first-degree chemical burn to the upper arm. This could include persistent skin discoloration, scarring, or other long-term effects that are being addressed in the current encounter. It is not for the initial acute injury.

• Always use this code as a secondary diagnosis, following a code that describes the nature of the sequela itself.
• Ensure the medical record clearly documents a prior first-degree corrosion burn to the upper arm and the current condition is a direct consequence.
• Verify the specific degree of burn and the exact anatomical location to ensure accurate code selection.
