How to ask your doctor for an autism referral

Why start with your GP or primary care doctor

Your general practitioner, family doctor or primary care provider is often the gatekeeper to specialist care. In the UK and similar systems, a GP referral is usually how adults reach an NHS autism assessment. In the US, many insurance plans require a primary care referral or prior authorization before covering an evaluation. Even when it is not required, your doctor can rule out medical issues, check for related conditions, and point you to local assessors.

Before the appointment

• Book an appointment just for this topic, and if possible request a longer slot.
• Write a one page summary. Doctors have limited time, and a written list helps you not forget things.
• Include examples from childhood and adulthood, grouped by area: social communication, routines and change, sensory experiences, interests, and how it affects your life.
• Note any related history: anxiety, depression, burnout, ADHD, eating difficulties, or a family member who is autistic.
• Decide whether to bring a partner or friend for support.

• Autism assessment preparation checklistPrepare for an adult autism assessment: note your reasons, examples now and in childhood, an informant, questions and needs, then print a one-page summary.

What to say: sample wording

Plain, direct language works best. You might say:

Then hand over your summary. Give your doctor time to read it.

What your doctor might do

• Ask further questions about your history and current difficulties.
• Use a brief screening questionnaire to decide on referral.
• Check for medical or mental health conditions that need attention.
• Refer you to a local adult autism service, psychologist or psychiatrist.
• Give you information about local referral routes, waiting times or how to self-refer.

If your doctor is unsure or says no

Some doctors know less about autism in adults, particularly in women or people who mask. If your request is refused:

1. Ask calmly for the reason, and whether there is anything else you could provide.
2. Ask for your request and the decision to be recorded in your notes.
3. Share relevant information, such as how difficulties affect work, health or relationships, or that masking hides them in short appointments.
4. Ask to see another doctor at the practice for a second opinion.
5. In the US, check whether your insurance lets you book a psychologist directly without a referral.
6. Ask your therapist or psychiatrist, if you have one, to refer you instead.

Making the appointment easier on yourself

Doctor's offices can be hard sensory environments, and appointments can feel rushed. It is reasonable to ask for adjustments: the first or last appointment of the day when the waiting room is quieter, waiting outside or in the car until called, a phone or video appointment, or permission to communicate partly in writing. If speaking feels difficult on the day, you can simply hand over your summary and say it explains why you are there.

If you have been told before that you seem fine, it can help to say at the start that you tend to appear calm in appointments even when things are hard. That framing gives your doctor a reason to look past first impressions.

After the referral

Ask your doctor where the referral is going, how long the wait is likely to be, and what support is available meanwhile. Write down the name of the service and any reference number. Keep a copy of your summary to update while you wait, and contact the service if you do not hear back within the timeframe you were given.

If you see the same doctor for other health issues, mention the referral at later visits. They may notice related patterns, such as sensory sensitivities affecting medical care, and adjust how they work with you.
