Q80.1

Billable

X-linked ichthyosis

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

What This Code Means

A genetic skin disorder passed through the X chromosome causing fish-scale-like skin, typically affecting males more severely than females.

Coding Tips

  • •Note the patient's sex as X-linked inheritance patterns differ between males and females
  • •Document corneal opacities if present, as this is a distinguishing feature of X-linked ichthyosis
