T23.0Burn of unspecified degree of wrist and hand

T23.0 is the ICD-10-CM diagnosis code for burn of unspecified degree of wrist and hand. 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 9 subcodes must be used instead.

Within T23, choose T23.0 (Burn of unspecified degree of wrist and hand) only when documentation doesn't support a more specific option: burn of first degree of wrist and hand (T23.1), burn of second degree of wrist and hand (T23.2), burn of third degree of wrist and hand (T23.3), corrosion of unspecified degree of wrist and hand (T23.4), corrosion of first degree of wrist and hand (T23.5), corrosion of second degree of wrist and hand (T23.6) and corrosion of third degree of wrist and hand (T23.7).

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.

Use an additional code for: external cause code to identify the source, place and intent of the burn (X00-X19, X75-X77, X96-X98, Y92).

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