About coding finger burn

The ICD-10-CM code for finger burn is T23.029 (Burn of unspecified degree of unspecified single finger (nail) except thumb). The official index lists 35 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T23.029.

Within T23.02, choose T23.029 (unspecified single finger (nail) except thumb) only when documentation doesn't support a more specific option: single right finger (nail) except thumb (T23.021) and single left finger (nail) except thumb (T23.022).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
