Q92 is a non-billable ICD-10-CM code category for other trisomies and partial trisomies of the autosomes, not elsewhere classified. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. The more specific codes under it are Q92.0 Whole chromosome trisomy, nonmosaicism (meiotic nondisjunction); Q92.1 Whole chromosome trisomy, mosaicism (mitotic nondisjunction); Q92.2 Partial trisomy; Q92.5 Duplications with other complex rearrangements and 4 more. Its coding notes include 1 Excludes1 entry and 2 Excludes2 entries.
Guidelines tip
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
Chapter 17 codes can be used for life. Manifestations that are an inherent part of a specifically coded anomaly are not coded separately. A corrected malformation is reported with a personal history code.
Excludes1
Not coded here. The listed conditions generally should not be reported together.
- trisomies of chromosomes 13, 18, 21 (Q90-Q91)
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
Also from chapter/block level (2 notes)
