About coding abruptio placentae

The ICD-10-CM code for abruptio placentae is O45.9 (Premature separation of placenta, unspecified). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O45.9.

Within O45, choose O45.9 (Premature separation of placenta, unspecified) only when documentation doesn't support a more specific option: premature separation of placenta with coagulation defect (O45.0) and other premature separation of placenta (O45.8).

To report this condition, pick the subcode that matches the documentation: O45.90 (unspecified trimester), O45.91 (first trimester), O45.92 (second trimester) and O45.93 (third trimester).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
