G44.099
BillableOther trigeminal autonomic cephalgias (TAC), not 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 respond adequately to treatment.
Coding Tips
- •Use this code only when the headache condition is a TAC variant but does not fit the more specific codes (cluster, paroxysmal hemicrania, or SUNCT)
- •Document the autonomic features present and the treatment response to justify the 'not intractable' designation
