O41 — Other disorders of amniotic fluid and membranes
Not billable
Is O41 billable?
No — O41 is a non-billable header code. O41 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 O41.

| Description | Other disorders of amniotic fluid and membranes |

| Valid for encounters | October 1, 2026 – September 30, 2027 |
Excludes1 — never code together
The conditions below can never be reported together with O41 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- encounter for suspected maternal and fetal conditions ruled out (Z03.7-)
Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O41 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 O41 to fully describe the condition. O41 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 O41, but a patient may have both at the same time. When documentation supports it, O41 and the excluded code may both be reported.
