About T53.0
T53.0 is the ICD-10-CM diagnosis code for toxic effects of carbon tetrachloride. It belongs to category T53 (toxic effect of halogen derivatives of aliphatic and aromatic hydrocarbons), 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 T53 (toxic effect of halogen derivatives of aliphatic and aromatic hydrocarbons), T53.0 is specifically for toxic effects of carbon tetrachloride. Related codes cover chloroform (T53.1), trichloroethylene (T53.2), tetrachloroethylene (T53.3), dichloromethane (T53.4), chlorofluorocarbons (T53.5), other halogen derivatives of aliphatic hydrocarbons (T53.6), other halogen derivatives of aromatic hydrocarbons (T53.7) and unspecified halogen derivatives of aliphatic and aromatic hydrocarbons (T53.9).
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.
