Other trigeminal autonomic cephalgias (TAC), intractable

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

What This Code Means

Other rare headache conditions involving the trigeminal nerve with autonomic symptoms (such as eye redness, tearing, or nasal congestion) that do not respond well to treatment.

Coding Tips

  • •This is a catch-all code for trigeminal autonomic cephalgia variants not specifically classified; ensure the condition truly fits TAC criteria
  • •Document the specific autonomic symptoms present and the intractable treatment status clearly
