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

This code indicates a healed or chronic first-degree burn affecting the right thumb, including the nail area. A first-degree burn involves only the outermost layer of skin (epidermis), typically presenting with redness and mild pain, but no blistering. The "sequela" designation signifies that this code is used for the long-term effects or complications of a past burn injury, not the initial acute injury.

Use this code when documenting a patient presenting with a residual condition or complication directly attributable to a previously sustained first-degree burn on their right thumb. This could include scarring, changes in skin texture, or nail deformities resulting from the original burn. It is appropriate for follow-up visits addressing these chronic effects, long after the acute burn has healed.

• Always assign an external cause code (V00-Y99) in conjunction with sequela codes to describe the circumstances of the original injury.
• Do not use this code for acute, active burn treatment; use codes from the T20-T25 range for initial burn encounters.
• Ensure documentation clearly links the current condition to a past burn injury of the right thumb.
