Q92.6
Marker chromosomes
Congenital malformations, deformations and chromosomal abnormalities
Heads up:this is a parent code. It's typically not directly billable — you need to drill down to a more specific child code (one with additional digits) to use on a claim.

How coders use this code
ICD-10-CM Q92.6 is a category (header) for marker chromosomes. It is generally not reported directly on a claim — coders drill down to a more specific child code (one with additional characters) that matches the documentation. Use the related codes below to find the billable code that fits, and verify against the annual NCHS/CMS guidelines.
