G44.051

Billable

Short lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), intractable

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

What This Code Means

A rare headache condition with very brief episodes of severe, stabbing pain on one side of the head with eye redness and tearing that does not respond well to treatment.

Coding Tips

  • •SUNCT headaches are characterized by very short duration attacks (15-120 seconds); ensure this temporal pattern is documented
  • •The intractable designation requires documentation of treatment failures; note specific medications attempted
