What to Do After an Autism Diagnosis: The First 90 Days

Week one: the four things that actually matter

A diagnosis day usually ends with a stack of pamphlets and no order of operations. This is the order that saves the most time later.

1. 1Get the full written evaluation report, not just the summary letter. Ask for a PDF. Almost every service you apply for will ask for it, and re-requesting it later takes weeks.
2. 2Request an evaluation in writing. Under three: your state's early intervention program. Three or older: your public school district's special education office. You do not need a referral, and you should keep a dated copy of the request.
3. 3Call the member services number on your insurance card and ask three specific questions: which autism-related services are covered, whether prior authorization is required, and whether the plan requires in-network providers.
4. 4Start one place to keep everything: the report, the insurance answers, provider names, dates, and the questions you want to ask next time. One place, not five.

Month one: build the map

Most families end up with more people involved than they expect: a pediatrician, an evaluating clinician, one to three therapists, a school team, an insurance case manager, and often a state program contact. Writing that list down once, with contact details and roles, is the single highest-return hour of admin in this whole process.

Questions worth asking every provider

• What specific goals are we working on, and how will we know they are working?
• How do you measure progress, and how often will I see that data?
• How do you handle it when my child says no or is distressed?
• How will you coordinate with the other people supporting my child?
• What should we be doing at home, and what should we deliberately not worry about?

A provider who welcomes those questions is a good sign. A provider who treats them as a challenge is information too.

By month three: the things people wish they had started earlier

• Ask about state Medicaid pathways. Some states offer waiver programs that provide services regardless of household income; waitlists are often long, so getting on a list early matters. See Medicaid waivers and autism services.
• Keep progress notes in one timeline, so patterns across sleep, food, school, and therapy are visible rather than scattered.
• Find one other caregiver who has been through it. Practical answers from a parent six months ahead of you are worth an enormous amount.
• Give yourself an actual break. Caregiver burnout is a real, well-documented risk, and respite programs exist specifically for this.

Frequently asked questions

Do I have to start therapy right away?

Earlier support is generally helpful, but a few weeks spent understanding coverage and choosing a provider carefully is not a loss. Getting on waitlists early while you decide is usually the practical compromise.

Should I tell my child's school about the diagnosis?

Sharing the report is what triggers the school evaluation and eligibility process, so most families do share it. You control what you share and when, and you can request that it be kept within the team supporting your child.

How do I tell my child they are autistic?

Many autistic adults describe knowing early, in matter-of-fact and positive language, as protective. Timing depends on your child, and clinicians and autistic-led organizations both publish guidance on how to have that conversation.
