G44

Other headache syndromes

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 7 more specific codes instead:

  • G44.0 Cluster headaches and other trigeminal autonomic cephalgias (TAC) (also a header)
  • G44.1 Vascular headache, not elsewhere classified
  • G44.2 Tension-type headache (also a header)
  • G44.3 Post-traumatic headache (also a header)
  • G44.4 Drug-induced headache, not elsewhere classified (also a header)
  • G44.5 Complicated headache syndromes (also a header)
  • G44.8 Other specified headache syndromes (also a header)

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
