T64 — Toxic effect of aflatoxin and other mycotoxin food contaminants
Is T64 billable?
No — T64 is a non-billable header code. T64 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 24 billable codes beneath T64.

Excludes1 — never code together — inherited from T51-T65
The conditions below can never be reported together with T64 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- contact with and (suspected) exposure to toxic substances (Z77.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside T64 to fully describe the condition. T64 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T51-T65
Report an additional code alongside T64 to fully describe the condition. T64 is sequenced first.
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T64, but a patient may have both at the same time. When documentation supports it, T64 and the excluded code may both be reported.

How long has T64 existed?
T64 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
