2022 ICD-10-CM Code T65.3X4A
Toxic effect of nitroderivatives and aminoderivatives of benzene and its homologues, undetermined, initial encounter

Version 2022
ICD-10:T65.3X4A
Short Description:Toxic eff of nitrodrv/aminodrv of benzn/homolog, undet, init
Long Description:Toxic effect of nitroderivatives and aminoderivatives of benzene and its homologues, undetermined, initial encounter
Status: Valid for Submission

Code Classification

  • Injury, poisoning and certain other consequences of external causes (S00–T98)
    • Toxic effects of substances chiefly nonmedicinal as to source (T51-T65)
      • Toxic effect of other and unspecified substances (T65)

T65.3X4A is a billable diagnosis code used to specify a medical diagnosis of toxic effect of nitroderivatives and aminoderivatives of benzene and its homologues, undetermined, initial encounter. The code T65.3X4A is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

T65.3X4A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like toxic effect of nitroderivatives and aminoderivatives of benzene and its homologues undetermined. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of other and unspecified substances (T65). Use the following options for the aplicable episode of care:

Table of Drugs and Chemicals

The parent code T65.3X4 of the current diagnosis code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.

According to ICD-10 coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.
