Episodic cluster headache, not intractable

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

What This Code Means

Severe headaches that occur in distinct clusters separated by headache-free periods and respond adequately to standard treatment.

Coding Tips

  • •The '9' indicates not intractable; document effective treatment response
  • •Clearly document the episodic pattern with remission periods to distinguish from chronic cluster headache
