Q92Other trisomies and partial trisomies of the autosomes, not elsewhere classified

Q92 is the ICD-10-CM diagnosis code for other trisomies and partial trisomies of the autosomes, not elsewhere classified. It belongs to block Q90-Q99 (chromosomal abnormalities, not elsewhere classified) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Q92.0 (nondisjunction)), Q92.1 (nondisjunction)), Q92.2 (trisomy), Q92.5 (rearrangements), Q92.6 (chromosomes), Q92.7 (polyploidy), Q92.8 (autosomes) and Q92.9 (unspecified).

Don't report Q92 together with the conditions in its Excludes1 note: trisomies of chromosomes 13, 18, 21 (Q90-Q91).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
