Burn of first degree of left toe(s) (nail), sequela

This code signifies a healed or residual condition resulting from a first-degree burn specifically affecting the toe(s) or toenail(s) on the left foot. A first-degree burn involves only the outermost layer of skin, causing redness and mild pain, but no blistering. The "sequela" indicates that the acute injury has passed, and the code is used to report a current problem that is a direct consequence of that prior burn.

Use this code when documenting a patient presenting with a long-term complication or residual effect directly attributable to a previously sustained first-degree burn on the left toe(s) or toenail(s). This could include persistent discoloration, altered sensation, or nail deformity that developed after the initial burn healed. It is appropriate when the burn itself is no longer an active injury requiring acute treatment.

• Always use an external cause code (V00-Y99) in conjunction with a sequela code to describe the circumstances of the original injury.
• Ensure the documentation clearly links the current condition to the previous first-degree burn of the left toe(s).
• Do not use this code for an active, acute first-degree burn; use the acute burn code (T25.132A) for initial encounters.
