Dissociated nystagmus

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

What This Code Means

A person has involuntary eye movements where each eye moves independently or differently from the other eye.

Coding Tips

  • •Document that the nystagmus is dissociated (eyes move differently) rather than conjugate (moving together)
  • •Note any associated neurological or vestibular findings that may explain the dissociated pattern
