My Botox treatment has been denied by my insurance for the first time after several years. I had an increase in migraines about six months ago so my neurologist prescribed Ajovy in addition to my Botox treatment. My migraines decreased and I continued the regimen, however today I got a letter denying my Botox treatment which was scheduled for 9/30. The Botox was denied because I am taking the Ajovy according to the letter. I’m going to file a grievance but what do I say that would yield the best results?
