Excessive vomiting in pregnancy

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 5 more specific codes instead:

O21.0 Mild hyperemesis gravidarum
O21.1 Hyperemesis gravidarum with metabolic disturbance
O21.2 Late vomiting of pregnancy
O21.8 Other vomiting complicating pregnancy
O21.9 Vomiting of pregnancy, unspecified

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 Excessive vomiting in pregnancy
