Corrosion of first degree of chin, sequela

This code signifies a first-degree burn injury to the chin, where the acute phase of the injury has resolved, and the code is being used to report a residual condition or complication arising from that past burn. A first-degree burn involves only the epidermis, causing redness and mild pain without blistering.

Use this code when documenting a patient presenting with a sequela (e.g., scarring, pigment changes, chronic pain) directly attributable to a previously sustained first-degree corrosion of the chin. This applies when the initial burn has healed, and the current encounter addresses a long-term consequence.

• Ensure the documentation clearly links the current condition to a past first-degree burn of the chin.
• The "S" seventh character indicates a sequela, meaning the initial injury has healed, and the current encounter is for a residual effect.
• Do not use this code for the initial treatment of an acute first-degree chin corrosion; use the appropriate acute phase code instead.
