Corrosion of first degree of other site of trunk, sequela

This code signifies a first-degree chemical burn (corrosion) affecting any part of the trunk, excluding the back, chest wall, or groin, and indicates that the burn is a long-term complication or late effect of an initial injury. A first-degree corrosion involves only the epidermis, presenting with redness and pain but no blistering.

Use this code when documenting a residual scar, discoloration, or other persistent issue resulting from a resolved first-degree chemical burn to an unspecified area of the trunk. This applies to follow-up encounters where the acute phase of the burn has passed, and the patient is being treated for the lasting effects.

• Ensure the documentation clearly states "sequela" or "late effect" of a first-degree chemical burn to the trunk.
• Confirm the burn is indeed first-degree and not a higher degree, as this code is specific to the mildest form.
• Verify the affected area is on the trunk but not specifically the back, chest wall, or groin, which have more specific codes.
