T23.021S
ICD-10-CMBurn of unspecified degree of single right finger (nail) except thumb, sequela
This code indicates a long-term complication or late effect resulting from a burn of an unspecified degree that affected a single finger on the right hand, excluding the thumb. The burn specifically involved the nail or nail bed area of that finger. The sequela could manifest as scarring, nail deformity, chronic pain, or functional impairment.
Use this code when documenting a patient presenting for treatment of a residual condition or complication directly attributable to a past burn injury to a single right finger (not the thumb), specifically involving the nail. This applies when the acute phase of the burn has passed, and the current encounter addresses the lasting effects.
