O30 — Multiple gestation

Not billable

Is O30 billable?

No — O30 is a non-billable header code. O30 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 60 billable codes beneath O30.
