T23.239Burn of second degree of unspecified multiple fingers (nail), not including thumb

T23.239 is the ICD-10-CM diagnosis code for burn of second degree of unspecified multiple fingers (nail), not including thumb. It belongs to category T23 (burn and corrosion of wrist and hand), block T20-T25 (burns and corrosions of external body surface, specified by site) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T23.23, choose T23.239 (unspecified multiple fingers (nail), not including thumb) only when documentation doesn't support a more specific option: multiple right fingers (nail), not including thumb (T23.231) and multiple left fingers (nail), not including thumb (T23.232).

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.
