T65.1 — Toxic effect of strychnine and its salts
Is T65.1 billable?
No — T65.1 is a non-billable header code. T65.1 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 12 billable codes beneath T65.1.

Excludes1 — never code together — inherited from T51-T65
The conditions below can never be reported together with T65.1 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 T65.1 to fully describe the condition. T65.1 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T51-T65
