O30.1 — Triplet pregnancy
Is O30.1 billable?
No — O30.1 is a non-billable header code. O30.1 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 20 billable codes beneath O30.1.

Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O30.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- supervision of normal pregnancy (Z34.-)
Use additional code — inherited from Chapter 15
Report an additional code alongside O30.1 to fully describe the condition. O30.1 is sequenced first.
- code, if applicable, from category Z3A, Weeks of gestation, to identify the specific week of the pregnancy, if known.
Excludes2 — not included here — inherited from Chapter 15
The conditions below are not part of O30.1, but a patient may have both at the same time. When documentation supports it, O30.1 and the excluded code may both be reported.
Code also — inherited from O30
Two codes may be needed to describe the condition fully. Whether O30.1 is sequenced first depends on the reason for the encounter.
- any complications specific to multiple gestation
