O41: Other disorders of amniotic fluid and membranes
O41 is a non-billable header ICD-10-CM code for other disorders of amniotic fluid and membranes. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code 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.

Excludes1: never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
