T65.29Toxic effect of other tobacco and nicotine

T65.29 is the ICD-10-CM diagnosis code for toxic effect of other tobacco and nicotine. It belongs to category T65 (toxic effect of other and unspecified substances), 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 4 subcodes must be used instead.

Within T65.2, choose T65.29 (other tobacco and nicotine) only when documentation doesn't support a more specific option: chewing tobacco (T65.21) and tobacco cigarettes (T65.22).

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.
