If you're looking for how to get an autism diagnosis in Montana, the state presents significant geographic challenges — Montana is the fourth largest state by area with fewer than 1.1 million people. Diagnostic resources are concentrated in Billings, Missoula, Great Falls, and Bozeman. Telehealth has become essential for rural Montana families. Montana's insurance mandate (enacted 2015) was a later adoption than most states.
