What’s Taking So Long? Understanding Delays in Autism Evaluations and What Families Can Do About It.

“Thank you for contacting the Developmental Medicine Clinic. Please note that our current waitlist for a comprehensive evaluation is approximately 12 to 24 months.” Heard that before? If you are a parent or caregiver who has tried to get an autism evaluation for your child, you already know how frustrating the process can be. Many families wait months to years for a single appointment. Some clinics stop taking new names because their lists are already too full. Meanwhile, your child’s development is regressing while you watch time tick by. These long waits are a real problem, and they happen for reasons that are easy to understand once you see the whole picture. The good news is that faster options now exist, and understanding why the system is so backed up can help you find them.

More People Are Asking for Evaluations

More families are looking for answers than ever before. Over the past 20 years, awareness of autism has grown a lot. Parents, teachers, and even adults themselves are much better at noticing possible signs. At the same time, the official rules doctors use to diagnose autism have gotten broader. That means more people now fit the description, including girls and people who are very good at hiding or masking their differences (Hirota and King, JAMA, 2023).

The numbers show this clearly. Not long ago, autism was identified in about 1 in 150 children. Today, roughly 1 in 36 children in the United States meet the criteria, and the most recent surveillance data push that number to about 1 in 31 (Messias et al., JAMA Network Open, 2026). That is a huge jump in a short time.

Demand has grown for other reasons too. Many schools and therapy programs will not provide extra help or special services until a child has a formal diagnosis from a trained specialist. On top of that, a growing number of adults who were missed as children are now seeking evaluations for the first time. All of these groups are reaching out at once, and the system was never built to handle that much demand.

The COVID years made things worse. Many clinics paused or slowed down evaluations for months. When they reopened, the delayed cases piled up on top of all the new ones. Families are still feeling the effects of that backlog today.

Not Enough Specialists

The second big problem is simple: there are not enough trained people to do these evaluations. A thorough autism evaluation is usually done by a psychologist, a developmental pediatrician, or another clinician with special training. Learning to use the assessment tools correctly takes time, and not many professionals complete that training. When demand is high and the trained workforce is small, long waitlists are the natural result (de Marchena et al., Autism, 2026).

Where you live matters too. Big cities usually have more clinics and more specialists to choose from. Specialists tend to cluster in metropolitan areas, so families in smaller towns and rural areas often have far fewer options (McNally Keehn et al., Pediatrics, 2023). Some have to drive hours for a single visit, take time off work, and arrange care for their other children just to be seen. These travel and scheduling hurdles stretch the wait even longer.

Evaluations Take a Lot of Time

Even when a clinic has openings, each evaluation takes many hours. The appointment itself is only part of the work. The clinician also gathers history from parents and teachers, scores standardized tests, writes a detailed report, and handles insurance paperwork. All of that adds up quickly, so each professional can only finish a limited number of evaluations each week.

There is also no single, standard way every clinic does things. Different offices use different steps and different forms, which can create extra delays and confusion for families moving between providers.

The Insurance and Medicaid Problem

Money plays a big role as well. These evaluations are expensive to deliver, and insurance often does not pay enough to cover the real cost of the work. This is an even bigger problem with Medicaid. On average, state Medicaid programs pay far less than Medicare or private insurance for the same services, and the main billing code for developmental evaluations may not pay for more than the first hour, even though these visits often take three to five hours or more (Hudak et al., American Academy of Pediatrics, 2026).

Because the math does not work, some practices simply cannot afford to take many Medicaid patients, and some that once accepted Medicaid have stopped taking it altogether. Nationwide, far fewer providers accept new Medicaid patients than accept new patients with private insurance (Hudak et al., American Academy of Pediatrics, 2026). States also differ widely in what they will cover, and some do not reliably pay for autism-related care at all (Schor and Johnson, JAMA Pediatrics, 2021). The result is that families who rely on Medicaid often face the longest waits and the fewest choices.

How Out-of-Network Care Can Help

One option many families do not know about is seeing an out-of-network (OON) provider. When a clinic is not locked into a long list of insurance contracts, it can skip a lot of the red tape, like slow approvals, restrictive billing rules, and the paperwork bottlenecks that tie up in-network offices. That streamlined setup lets these practices open more appointment slots and see more people, more quickly.

For a family stuck on a waitlist that is many months long, an out-of-network evaluation can mean getting clear answers in weeks instead of seasons. Many plans also offer some out-of-network reimbursement, so it is always worth asking your insurer what they will cover. The point is simple: fewer administrative roadblocks often mean faster access.

Commercial Insurance? Know Your Parity Rights

If you have private or employer-based insurance, it pays to learn about parity laws before you assume something is not covered. A federal law, the Mental Health Parity and Addiction Equity Act of 2008, requires many health plans to cover mental and behavioral health services on the same terms they use for regular medical care, meaning they cannot quietly apply stricter limits or harder approval rules to these services (Carlo et al., JAMA, 2020). On top of that, all 50 states and the District of Columbia now have autism insurance mandates that require commercial plans to cover autism services, including diagnostic evaluations and therapies, though the exact rules vary quite a bit from state to state (Choi et al., Maternal and Child Health Journal, 2020). Research has found that these laws expanded the number of children getting covered autism care, and that parity actually lowered families’ share of the cost rather than raising it (Stuart et al., Health Affairs, 2017; Mandell and Barry, New England Journal of Medicine, 2017). The takeaway for families: call your plan, ask specifically how your state’s autism mandate and parity protections apply to evaluations, and do not take a quick “no” at face value, since what your plan must cover may be broader than a first phone call suggests.

Why the Waits Matter

These delays are not just inconvenient. They can affect a child’s future. Signs of autism can often be seen in the first two years of life, yet the average age of diagnosis in the United States is still around four years old (McNally Keehn et al., Pediatrics, 2023). The early years are a powerful window for learning and growth, and support tends to help most during that time.

Research backs this up. Early intensive behavioral programs have been shown to improve children’s everyday living skills, language, and overall development (Reichow et al., Cochrane Database of Systematic Reviews, 2018). Parent-coaching programs started early can boost a young child’s communication and social connection, and some of those gains last for years (Lord et al., The Lancet, 2018). Children who are identified and supported earlier often do better with language, learning, and daily skills down the road (Lai et al., The Lancet Neurology, 2020). While families sit on a waitlist, children can miss out on these therapies and school services during the very window when they help the most. Adults face their own version of this problem, waiting for answers and for accommodations that could help them at work and in everyday life.

A Faster Option Exists

The good news is that families are not stuck with the longest waitlists. Some practices have built new models designed to cut the wait down dramatically. Tools like telehealth visits and FDA-authorized digital aids now make it possible to reach clear, accurate answers without the usual months-long backlog, and research has shown that remote evaluations can closely match in-person results for many people (Stavropoulos et al., PLoS One, 2021; Sutherland et al., Autism Research, 2025).

At RiseNow Autism Innovations, most families are scheduled for an evaluation within 3 to 4 weeks of reaching out. The clinic uses FDA approved telehealth options, along with trusted tools to give families clear answers without the usual multi-month wait. Because RiseNow works as an out-of-network practice, it can sidestep much of the insurance red tape that bogs down traditional clinics, which is a big part of how it keeps wait times short and opens more spots for families who need them. Services are available for children through adults across Pennsylvania, New Jersey, and Delaware, and virtual visits are helping extend that reach even further.

Long waitlists are not going to disappear overnight. They come from high demand, too few trained specialists, time-heavy evaluations, and real payment and Medicaid challenges. But families who need answers sooner do have choices beyond the longest traditional lists. Getting a timely, accurate evaluation helps people move from uncertainty to support at the moment it matters most.
