Antepartum hemorrhage, unspecified

Not billableICD-10-CM diagnosis code.

O46.90 Antepartum hemorrhage, unspecified, unspecified trimester
O46.91 Antepartum hemorrhage, unspecified, first trimester
O46.92 Antepartum hemorrhage, unspecified, second trimester
O46.93 Antepartum hemorrhage, unspecified, third trimester

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2012 Added to the draft code set draft Antepartum hemorrhage, unspecified
