I was in your shoes myself. My child lost his speech and was non-verbal at 17 months. Our insurance is Kaiser Permanente, they tell people only about services they cover, not what your child actually needs. We went to OHSU's Autism Clinic for evaluation. It's very expensive (up to $2,500) but very thorough and Kaiser, after denials, paid it, then took money back. We are still going through appeals for that. It was worth it. OHSU recommended 20-25 hours/week of therapy and it did wonders--our child speaks again and is in a mainstream preschool with typical peers. You need to act NOW, the younger your child is the better. Also, contact your legislators about Oregon bills SB 555/HB 2214--mandate for insurance to cover autism. This is legislation written by parents (an Oregon Senator is also a parent of an autistic child) and advocacy organizations to make insurance companies in Oregon pay for diagnosis and treatment of autism. 24 other states already have such mandates but in Oregon insurance industry (including Kaiser) has been fighting hard against this legislation and we need more support from parents, otherwise many kids will be left without treatments that can help greatly (47% of young kids may regain "typical" function and 40% make significant progress with intensive therapy like ABA). So, act now to help your child and other people in Oregon. The legislation applies not only to austim but also Asperger's, PDD-NOS, etc. Call your legislators today, we want this passed as soon as possible. The state of Arkansas passed this mandante in 2011 in 29 days! Oregon is so far behind and there are so many kids and adults that really need help. And I would greatly recommend OHSU.
