Q98

Other sex chromosome abnormalities, male phenotype, not elsewhere classified

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 9 more specific codes instead:

  • Q98.0 Klinefelter syndrome karyotype 47, XXY
  • Q98.1 Klinefelter syndrome, male with more than two X chromosomes
  • Q98.3 Other male with 46, XX karyotype
  • Q98.4 Klinefelter syndrome, unspecified
  • Q98.5 Karyotype 47, XYY
  • Q98.6 Male with structurally abnormal sex chromosome
  • Q98.7 Male with sex chromosome mosaicism
  • Q98.8 Other specified sex chromosome abnormalities, male phenotype
  • Q98.9 Sex chromosome abnormality, male phenotype, 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.
