Burn of second degree of right thumb (nail), sequela

This code indicates a second-degree burn affecting the right thumb, specifically its nail or surrounding tissue, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication. A second-degree burn involves damage to the epidermis and dermis, characterized by blistering and pain. The "sequela" designation signifies that the current encounter addresses a long-term effect of this past burn.

Use this code when documenting a patient visit for a complication or residual condition directly resulting from a previously sustained second-degree burn to the right thumb. Examples include scar contracture, chronic pain, nail deformity, or impaired function that persists after the initial burn has healed. This code is not for the initial treatment of the acute burn.

• Always assign a secondary code to describe the specific nature of the sequela (e.g., scar, contracture, chronic pain).
• Ensure documentation clearly links the current condition to the past burn injury of the right thumb.
• Do not use this code for current, active burn treatment; use acute burn codes for those encounters.
