ICD-10-CM Q92
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

Q92 is a non-billable ICD-10-CM category code for other trisomies and partial trisomies of the autosomes, not elsewhere classified, so it cannot be submitted on claims. Use a more specific code from this category instead, such as Q92.0, Q92.1, Q92.2, and Q92.5.

Specific Coding for Oth trisomies and partial trisomies of the autosomes, NECOverview

Non-specific codes like Q92 require more characters. Use one of these billable codes instead:

  • Use Q92.0 for Whole chromosome trisomy, nonmosaicism (meiotic nondisjunction)

  • Use Q92.1 for Whole chromosome trisomy, mosaicism (mitotic nondisjunction)

  • Use Q92.2 for Partial trisomy

  • Use Q92.5 for Duplications with other complex rearrangements

  • Q92.6 for Marker chromosomes

  • Use Q92.61 for Marker chromosomes in normal individual

  • Use Q92.62 for Marker chromosomes in abnormal individual

  • Use Q92.7 for Triploidy and polyploidy

  • Use Q92.8 for Other specified trisomies and partial trisomies of autosomes

  • Use Q92.9 for Trisomy and partial trisomy of autosomes, unspecified

Genetic Disorders

Genetic disorders are health conditions caused by changes (also called mutations or variants) in your genes. Genes are parts of DNA found in your cells that carry instructions for how your body grows, develops, and functions. Many genes tell your body how to make proteins, which are needed for your body to work properly.

Questions About Q92Overview

Is Q92 a billable code?

No. This is a category header that groups the codes for other trisomies and partial trisomies of the autosomes, not elsewhere classified, and headers cannot be submitted on claims. Claims for other trisomies and partial trisomies of the autosomes, not elsewhere classified need a more specific code from this category, such as Q92.0, Q92.1, and Q92.2.
