O14 — Pre-eclampsia
Is O14 billable?
No — O14 is a non-billable header code. O14 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 O14.

Excludes1 — never code together
The conditions below can never be reported together with O14 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- pre-existing hypertension with pre-eclampsia (O11)
Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O14 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 O14 to fully describe the condition. O14 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 O14, but a patient may have both at the same time. When documentation supports it, O14 and the excluded code may both be reported.
