T54.0X — Toxic effects of phenol and phenol homologues
Is T54.0X billable?
No — T54.0X is a non-billable header code. T54.0X 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 T54.0X.

Excludes1 — never code together — inherited from T51-T65
The conditions below can never be reported together with T54.0X 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 T54.0X to fully describe the condition. T54.0X is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)

Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T54.0X, but a patient may have both at the same time. When documentation supports it, T54.0X and the excluded code may both be reported.

How long has T54.0X existed?
T54.0X 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.
