Weeks of gestation

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:

Z3A.0 Weeks of gestation of pregnancy, unspecified or less than 10 weeks (also a header)
Z3A.1 Weeks of gestation of pregnancy, weeks 10-19 (also a header)
Z3A.2 Weeks of gestation of pregnancy, weeks 20-29 (also a header)
Z3A.3 Weeks of gestation of pregnancy, weeks 30-39 (also a header)
Z3A.4 Weeks of gestation of pregnancy, weeks 40 or greater (also a header)

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 Weeks of gestation
