Corrosion of first degree of left wrist, sequela

This code indicates a first-degree burn injury to the left wrist that has healed, but the patient is still experiencing residual effects or complications from that past injury. These sequelae could include scarring, changes in skin pigmentation, or persistent sensitivity in the affected area.

Use this code when documenting a patient encounter for a condition that is a direct consequence of a first-degree corrosion (chemical burn) to the left wrist that occurred in the past. This applies when the acute injury has resolved, and the current treatment or evaluation is for the long-term effects.

• Assign this code only for the sequela of a first-degree corrosion.
• Ensure the documentation clearly links the current condition to a previous left wrist corrosion.
• This "S" seventh character indicates sequela, meaning the initial injury has healed, and the patient is being treated for a residual effect.
