Q96.1

Billable

Karyotype 46, X iso (Xq)

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A chromosomal condition where a person has 46 chromosomes but one X chromosome is abnormal (isochromosome Xq), affecting sexual development and physical characteristics.

Coding Tips

  • •This is a specific karyotype variant of Turner's syndrome; document the genetic test results in the medical record
  • •Use this code when genetic testing confirms the isochromosome Xq pattern rather than the unspecified Turner's code
