Receiving an autism diagnosis can be a turning point for families. For many parents, the diagnosis provides answers, access to support services, and a clearer path forward. However, what often catches families off guard are the autism diagnosis costs that begin to accumulate long after the initial evaluation. From therapy appointments to lost work hours, these expenses can place significant pressure on household budgets, even when insurance coverage is available. Understanding these hidden costs can help families prepare financially and make informed decisions about care.
