T23.149S
ICD-10-CMBurn of first degree of unspecified multiple fingers (nail), including thumb, sequela
This code indicates a healed or residual effect from a first-degree burn affecting multiple fingers, including the thumb, where the specific finger(s) are not documented. A first-degree burn involves only the epidermis, causing redness and pain without blistering. The "sequela" designation signifies that this code is used for complications or conditions arising directly from the initial burn injury, even after the acute phase has passed.
Use this code when documenting a patient presenting with a long-term consequence or scar from a superficial burn to an unspecified number of fingers, including the thumb, that occurred in the past. This applies to follow-up visits where the primary reason for encounter is related to the residual effects of the burn, such as scar tissue or persistent sensitivity, rather than the acute injury itself.
