Billable

Usher syndrome, type 2

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

What This Code Means

A genetic disorder causing progressive hearing loss and vision loss (retinitis pigmentosa) that typically begins in adolescence or early adulthood, with a slower progression than type 1.

Coding Tips

  • •Code associated hearing loss and vision loss separately; type 2 typically has later onset and slower progression than type 1
  • •Document the timeline of symptom onset to differentiate from other Usher syndrome types
