Partial trisomy
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.
- FY2007 Added to the draft code set draft Partial trisomy
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 Q92 Other trisomies and partial trisomies of the autosomes, not elsewhere classified
Excludes1 - never coded here
- trisomies of chromosomes 13, 18, 21 (Q90-Q91)
Includes
- unbalanced translocations and insertions
Inherited from the Q90-Q99 section Chromosomal abnormalities, not elsewhere classified (Q90-Q99)
Excludes2 - not included here
- mitochondrial metabolic disorders (E88.4-)
How CDC's index refers to this code
Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
- Reduplication
- Additional > chromosome
- Duplication, duplex > chromosome NEC
- Trisomy > chromosome specified NEC > partial
