About Q93

Q93 is the ICD-10-CM diagnosis code for Monosomies and deletions from 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 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Q93.0 (nondisjunction)), Q93.1 (nondisjunction)), Q93.2 (isochromosome), Q93.3 (4), Q93.4 (5), Q93.5 (chromosome), Q93.7 (rearrangements), Q93.8 (autosomes) and 1 more.

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