Coverage decision - Covered with conditions
Botulinum toxin products require prior authorization. Authorization criteria and coverage limitations depend on the condition being treated. For migraine headaches, coverage criteria are a combined product of the state’s Health Technology Clinical Committee (HTCC) and L&I. You can request authorization by completing and submitting the prior authorization form for chronic migraine or for non-migraine indications. Note that botulinum toxin products are covered only for FDA-approved uses, with the exception of botulinumtoxinA formulations for cervicobrachial syndrome.
OnabotulinumtoxinA for prevention of chronic migraine (up to five courses)
Additional L&I criteria:
- Chronic migraine diagnosis is causally related to an accepted industrial injury or occupational disease.
- Patient has kept a daily headache diary for at least three months to confirm diagnosis and establish baseline headache frequency.
- Patient is at least 18 years old.
HTCC reviewed the treatment of chronic migraine and chronic tension-type headache in May 2017 and finalized the coverage determination on July 14, 2017. HTCC then revised the determination on July 13, 2018 to remove the following requirement for discontinuation, “Has changed to episodic migraine (defined as < 15 headache days per month).”
Effective date of initial coverage decision is 12/1/17. Decision was revised on 10/1/18, which is retroactive to 12/1/17.

A maximum of four courses of injections may be authorized per year, with prior authorization.
