T58.0 — Toxic effect of carbon monoxide from motor vehicle exhaust
Is T58.0 billable?
No — T58.0 is a non-billable header code. T58.0 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 T58.0.

- Toxic effect of exhaust gas from gas engine
- Toxic effect of exhaust gas from motor pump
Excludes1 — never code together — inherited from T51-T65
The conditions below can never be reported together with T58.0 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 T58.0 to fully describe the condition. T58.0 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 T58.0 to fully describe the condition. T58.0 is sequenced first.
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T58.0, but a patient may have both at the same time. When documentation supports it, T58.0 and the excluded code may both be reported.
