O12.0 — Gestational edema
Is O12.0 billable?
No — O12.0 is a non-billable header code. O12.0 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 6 billable codes beneath O12.0.

How is O12.0 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to O12.0. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Pregnancy › complicated by › edema (single) (uterine)
Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O12.0 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 O12.0 to fully describe the condition. O12.0 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 O12.0, but a patient may have both at the same time. When documentation supports it, O12.0 and the excluded code may both be reported.
