If you want to get coverage for private speech, OT, or ABA through your family's health insurance, you will need to get a medical diagnosis. A developmental pediatrician or a pediatric neurologist would be able to give a medical diagnosis.

Absolutely. If he has autism an is age 2 a special needs preschool program and services would likely benefit him greatly. For this you need a diagnosis. On a diagnosis there is an area for recommendations. Where services are recommended, your school district should arrange for servicing - likely in a preschool if warranted in the recommendations. The CPSE (Committee for Preschool Education)can make these recommendations to provide services and programming. Early intervention is the strongest asset for any child with autism. Delay will only be of no benefit.

A psychiatrist diagnosed my son...then when we moved the school diagnosed him and the Star program (a autism program in Ky)also diagnosed him

Well then I guess he's technically diagnosed. His pediatrician and he pediatric neurologist all agree with the Autism diagnosis. I guess I wasn't even really sure if there was a difference. Our insurance already covers a portion of his therapies. Just wasn't sure if there was a major difference between an educational and medical diagnosis and I didn't want it to affect him in any way in the future if we had one and not another. Thanks for all the great advice.

Definitely. When there's a clean diagnosis, the treatments are much more narrow, but still YOU need to confirm how valid it is. The more you know about the specifics, the better chance Hayden will have in 'adjusting' to the Neurotypical world.

Child and Family Psychological Services (Phone number can only be seen by the question and answer creators) came up after a search for 'autism' came up for your area. Michigan State (Phone number can only be seen by the question and answer creators) was a 2nd reference in your Hood. 6 others showed up in Grand Rapids north of you, including Hope Network/Center for Autism, (Phone number can only be seen by the question and answer creators) looks like a good contact also.
