T23.342 is the ICD-10-CM diagnosis code for burn of third degree of multiple left fingers (nail), 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.
