Trisomy 18 and Trisomy 13

Not billableICD-10-CM diagnosis code.

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

Submit one of these 8 more specific codes instead:

Q91.0 Trisomy 18, nonmosaicism (meiotic nondisjunction)
Q91.1 Trisomy 18, mosaicism (mitotic nondisjunction)
Q91.2 Trisomy 18, translocation
Q91.3 Trisomy 18, unspecified
Q91.4 Trisomy 13, nonmosaicism (meiotic nondisjunction)
Q91.5 Trisomy 13, mosaicism (mitotic nondisjunction)
Q91.6 Trisomy 13, translocation
Q91.7 Trisomy 13, 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 Trisomy 18 and Trisomy 13
