Q93.8Other deletions from the autosomes

Q93.8 is the ICD-10-CM diagnosis code for other deletions from the autosomes. It belongs to category Q93 (Monosomies and deletions from the autosomes, not elsewhere classified), 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 4 subcodes must be used instead.

Within Q93, choose Q93.8 (Other deletions from the autosomes) only when documentation doesn't support a more specific option: whole chromosome monosomy, nonmosaicism (meiotic nondisjunction) (Q93.0), whole chromosome monosomy, mosaicism (mitotic nondisjunction) (Q93.1), chromosome replaced with ring, dicentric or isochromosome (Q93.2), deletion of short arm of chromosome 4 (Q93.3), deletion of short arm of chromosome 5 (Q93.4), other deletions of part of a chromosome (Q93.5), deletions with other complex rearrangements (Q93.7) and deletion from autosomes, unspecified (Q93.9).

To report this condition, pick the subcode that matches the documentation: Q93.81 (syndrome), Q93.82 (syndrome), Q93.88 (microdeletions) and Q93.89 (autosomes).

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