Corrosion of first degree of left palm, sequela

This code signifies a first-degree chemical burn (corrosion) affecting the palm of the left hand, where the acute injury has healed but residual effects or complications are still present. These sequelae could include scarring, changes in skin pigmentation, or chronic pain resulting from the original corrosive exposure.

Use this code when documenting a patient presenting with long-term complications or residual conditions directly attributable to a first-degree chemical burn on their left palm, after the initial healing phase is complete. This applies to follow-up encounters where the focus is on managing these persistent issues, not the acute injury itself.

• Always assign this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., scar, chronic pain).
• Ensure documentation clearly states the burn was chemical (corrosion) and located on the left palm.
• The "S" seventh character indicates sequela, meaning the acute phase of the injury has passed.
