Coding structure:

ICD-10 code T43 is based on the following Tabular structure:

    • Category T43: Poisoning by, adverse effect of and underdosing of psychotropic drugs, not elsewhere classified
Section T36-T50 — Poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances

The drug giving rise to the adverse effect should be identified by use of codes from categories T36-T50 with fifth or sixth character 5.
