About T52.0

T52.0 is the ICD-10-CM diagnosis code for toxic effects of petroleum products. It belongs to category T52 (toxic effect of organic solvents), 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 1 subcodes must be used instead.

Within T52 (toxic effect of organic solvents), T52.0 is specifically for toxic effects of petroleum products. Related codes cover benzene (T52.1), homologues of benzene (T52.2), glycols (T52.3), ketones (T52.4), other organic solvents (T52.8) and unspecified organic solvent (T52.9).

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.
