Abnormal biochemical finding on antenatal screening of mother
ValidICD-10-CM diagnosis code.
Valid for claims with a date of service in the current code year.
What has happened to this code
Every change the publisher made, from 2007 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.

Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from O28 Abnormal findings on antenatal screening of mother
Excludes1 - never coded here
- diagnostic findings classified elsewhere - see Alphabetical Index
Inherited from the O20-O29 section Other maternal disorders predominantly related to pregnancy (O20-O29)
Excludes2 - not included here
- maternal care related to the fetus and amniotic cavity and possible delivery problems (O30-O48)
- maternal diseases classifiable elsewhere but complicating pregnancy, labor and delivery, and the puerperium (O98-O99)
How CDC's index refers to this code
