Questions About This Page

How do I find the right code for a specific drug?

Type the substance into the filter above. Every code on this page carries its full substance list from the Table of Drugs and Chemicals. For the complete six-column table, use the Table of Drugs and Chemicals.

Do these codes need an external cause code?

No. Poisoning, adverse effect, and underdosing codes from the T36 to T65 range carry the intent inside the code itself, so no additional external cause code is reported with them.

What 7th character do these codes take?

A for the initial encounter during active treatment, D for subsequent encounters during recovery, and S for sequela when coding late effects.

How many intentional poisoning codes are there?

The FY 2026 dataset contains 287 intentional poisoning codes across 30 code blocks.
