Q92.7Triploidy and polyploidy

Q92.7 is the ICD-10-CM diagnosis code for Triploidy and polyploidy. It belongs to category Q92 (other trisomies and partial trisomies of 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q92 (other trisomies and partial trisomies of the autosomes, not elsewhere classified), Q92.7 is specifically for Triploidy and polyploidy. Related codes cover whole chromosome trisomy, nonmosaicism (meiotic nondisjunction) (Q92.0), whole chromosome trisomy, mosaicism (mitotic nondisjunction) (Q92.1), partial trisomy (Q92.2), Duplications with other complex rearrangements (Q92.5), marker chromosomes (Q92.6), other specified trisomies and partial trisomies of autosomes (Q92.8) and trisomy and partial trisomy of autosomes, unspecified (Q92.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

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

Before ICD-10, this condition was coded in ICD-9-CM as 758.5 (other conditions due to autosomal anomalies).
