O48 — Late pregnancy
Is O48 billable?
No — O48 is a non-billable header code. O48 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 2 billable codes beneath O48.

Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O48 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 O48 to fully describe the condition. O48 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 O48, but a patient may have both at the same time. When documentation supports it, O48 and the excluded code may both be reported.
