About T51
T51 is the ICD-10-CM diagnosis code for toxic effect of alcohol. It belongs to block T51-T65 (toxic effects of substances chiefly nonmedicinal as to source) 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 6 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: T51.0 (ethanol), T51.1 (methanol), T51.2 (2-Propanol), T51.3 (oil), T51.8 (alcohols) and T51.9 (alcohol).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
