O41 ICD-10-CM Code: Other disorders of amniotic fluid and membranes
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.
Official Registry Overview & Definition
Official Tabular Instructional Notes
Sequencing, inclusion, and exclusion notes published for O41 in the official ICD-10-CM tabular list.
Excludes1 — Not Coded Here
Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Frequently Compared Codes
The official Excludes notes on O41 name these codes. Each comparison page covers when the two can — or must not — be reported together.
Change history
No changes recorded for this code — unchanged since the FY2016 baseline of the change ledger.
Verify Before Coding
- Not billable as written — a more specific code is required: O41.00X0, O41.00X1, O41.00X2, O41.00X3, O41.00X4.
- Requires a 7th character. "One of the following 7th characters is to be assigned to each code under category O41. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from category O41 that has a 7th character of 1 through 9." Options: O41.00X0, O41.00X1, O41.00X2, O41.00X3, O41.00X4, O41.00X5

Frequently Asked Questions (FAQ) & Clinical Guidance
Can O41 be billed directly?
No. O41 (Other disorders of amniotic fluid and membranes) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
Does O41 require a 7th character?
Yes. One of the following 7th characters is to be assigned to each code under category O41. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from category O41 that has a 7th character of 1 through 9.; 0: not applicable or unspecified; 1: fetus 1; 2: fetus 2; 3: fetus 3; 4: fetus 4; 5: fetus 5; 9: other fetus.
