O9A — Maternal malignant neoplasms, traumatic injuries and abuse classifiable elsewhere but complicating pregnancy, childbirth and the puerperium
Is O9A billable?
No — O9A is a non-billable header code. O9A 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 30 billable codes beneath O9A.

Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O9A 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 O9A to fully describe the condition. O9A 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 O9A, but a patient may have both at the same time. When documentation supports it, O9A and the excluded code may both be reported.
