About T23
T23 is the ICD-10-CM diagnosis code for burn and corrosion of wrist and hand. It belongs to 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 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: T23.0 (hand), T23.1 (hand), T23.2 (hand), T23.3 (hand), T23.4 (hand), T23.5 (hand), T23.6 (hand) and T23.7 (hand).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
