Chronic post-traumatic headache, intractable

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

What This Code Means

A persistent headache lasting months or longer that started after a head injury and does not respond well to standard treatments.

Coding Tips

  • •Document that symptoms persist for at least 3 months post-trauma to establish chronicity
  • •Ensure documentation clearly indicates failed treatment attempts to justify 'intractable' designation
