Step 1: Recognize Early Signs and Talk to Your Pediatrician
Many families first notice developmental differences in their child, such as delayed speech, limited eye contact, or repetitive behaviors. Trust your instincts. Schedule an appointment with your child's pediatrician or primary care provider. They can perform developmental screenings and, if concerns arise, refer you to a specialist. In New Hampshire, pediatricians often use tools like the M-CHAT (Modified Checklist for Autism in Toddlers) for children aged 16 to 30 months.
When to Seek a Referral
If your child shows any of these signs, mention them to your doctor:
- No babbling or pointing by 12 months
- No single words by 16 months
- Loss of language or social skills at any age
- Little interest in playing with others or making eye contact
- Repetitive movements like hand-flapping or rocking
Your pediatrician can provide a referral to a developmental pediatrician, child psychologist, or neuropsychologist for a comprehensive evaluation.
Step 2: Choose the Right Specialist for an Autism Evaluation
In New Hampshire, several types of professionals can diagnose autism in children. The most common include:
- Developmental pediatricians - Doctors specializing in child development, often found at hospitals like Dartmouth-Hitchcock Medical Center in Lebanon or Elliot Hospital in Manchester.
- Child psychologists or neuropsychologists - Licensed professionals who conduct cognitive and behavioral assessments. Many private practices exist across the state.
- Child psychiatrists - Medical doctors who can diagnose and also prescribe medication if needed.
For children under age three, the NH Family Centered Early Supports and Services (FCESS) program provides free developmental evaluations. Contact your local Area Agency to schedule an assessment. This is a great first step for infants and toddlers.

Step 3: What to Expect During the Evaluation
An autism evaluation typically takes several hours and may be spread over multiple appointments. The specialist will:
- Interview you about your child's developmental history and behaviors
- Observe your child in structured and unstructured settings
- Use standardized tools like the ADOS-2 (Autism Diagnostic Observation Schedule)
- Assess communication, social interaction, and play skills
After the evaluation, the specialist will provide a written report with the diagnosis and recommendations. This report is crucial for accessing services, including ABA therapy.
Step 4: Understanding Costs and Insurance Coverage in New Hampshire
Autism evaluations can cost anywhere from $1,500 to $5,000 without insurance. However, most health insurance plans in New Hampshire, including employer-sponsored plans and individual plans, cover diagnostic evaluations for autism under the Affordable Care Act. New Hampshire also has a state law requiring insurance coverage for autism diagnosis and treatment.
Medicaid Coverage
NH Medicaid (called Granite Advantage) covers autism evaluations for eligible children. If you have Medicaid, contact your managed care organization (like WellSense or AmeriHealth Caritas) to find in-network providers. The FCESS program is free for children under three regardless of income.
Tips for Managing Costs
- Ask the specialist's office about self-pay discounts or sliding-scale fees.
- Check if your insurance requires pre-authorization for the evaluation.
- Keep all receipts and reports for tax purposes or reimbursement.

Step 5: After the Diagnosis - Next Steps for Your Child
Once you have a diagnosis, you can access a range of services. In New Hampshire, early intervention is key. For children under three, continue with FCESS for therapies like speech and occupational therapy. For children three and older, contact your local school district for an evaluation under the Individuals with Disabilities Education Act (IDEA) to develop an Individualized Education Program (IEP).
ABA therapy is a common recommendation. Many insurance plans cover ABA, and you can find vetted, BCBA-led providers through a free matching service like ABA Therapy Now. They help connect you with clinics in New Hampshire that meet your child's needs and accept your insurance.
