The diagnosis is good not matter what state you are in. I work in the medical field and an ICD10 is an IVD10 and part of the patients medical record. I left Florida because their services are horrible so this does not surprise me.

I know form moving state to state the school systems want new evaluations most times but that is just for services in school. With that being said they should not need a diagnosis again because it is part of the medical record.

We moved to Florida from South Carolina. I haven't run into any situations where his diagnosis has been questioned.

I have never had it done, but I have heard of it a few times. I am not certain why it's done, but perhaps how it is diagnosed state-by-state could play a role in it. While the diagnosis and codes are the same, the way they want proof of a diagnosis may be different.

For example, the way various specialists come to a diagnosis is very different, even. Some want to monitor the child, perform various tests, questionnaires and so forth, others are willing to diagnose simply by speaking to the school and/or caregivers.

In Ohio, my grandmother was getting my cousin tested for autism. He's mentally challenged, and this was diagnosed practically from birth, but the idea he was possibly on the spectrum did not come up until he was in his late teens. They wanted him tested but the battery of tests they did were too overwhelming for my cousin to handle and my grandma and aunt halted the process and decided that the help he receives already for his mental disability was enough to get him the help he needed without an autism diagnosis. (This was through a pediatric psychologist)

However, my son was diagnosed much more simply, I ended up seeing a pediatric neurologist. The school suggested he had a problem and was not allowed to say what they "thought" was wrong with my son and instead had his teacher and I compile some questionnaires and I presented them to a neurologist who refused to even look at them before she diagnosed him (even though the markers clearly indicated an autism diagnosis) she wanted to see everything first hand and not be swayed by papers. Instead, she talked to him, watched him play for 30 minutes doing various activities and asked us a bunch of questions related to milestones that were never even mentioned during any of his wellness checkups.. We walked out of her office an hour later with his diagnosis.

I went to a therapist that specializes in autism for my diagnosis.

It could be, that they feel a diagnosis needs to be done under a set of standards regulated by the state in order to accept it.

I saw the McKay grant. Unfortunately, my children won't qualify until next school year. It says that they must attend a Florida public school for an entire school-year (August-June) before I can apply for them.

There is a McKay grant you can apply for in Florida that will cover some costs, you may want to apply for that.
