Corrosion of first degree of unspecified palm, sequela

This code signifies a healed first-degree burn on an unspecified palm that resulted from corrosive chemical exposure, with the patient now experiencing a long-term effect or complication from that injury. It indicates that the acute phase of the burn has passed, but the patient continues to have a related issue.

Use this code when documenting a patient presenting with a sequela (e.g., scar tissue, chronic pain, restricted movement) from a previously sustained first-degree corrosive burn to the palm. This applies to follow-up encounters where the primary reason for the visit is to address the lasting effects of the original injury, not the acute burn itself.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the corrosive exposure.
• Ensure the medical record clearly documents the burn as first-degree and located on the palm.
• The "S" in the seventh character indicates sequela; do not use for initial or subsequent encounters for the acute burn.
