Your child turns 18 and you realize you don't know a single adult doctor who treats people with cerebral palsy. Or autism. Or Down syndrome.

You've been seeing the same pediatrician for 15 years. They know your child's baseline, their communication style, what medications worked and which ones didn't. Now you're supposed to find someone new who will start from scratch, and you don't know where to begin.

The transition from pediatric to adult healthcare is a documented gap. Here's the practical roadmap: what you do at 14, what you do at 17, what documents you build, and how to find providers who will take your call.

Start at 14: Build Self-Advocacy Skills Before You Need Them

The work of transition starts years before you leave your pediatrician's office. At 14 to 16, the priority isn't finding an adult doctor yet. It's building the skills your young adult will need to navigate adult care with or without support.

Can your child explain their diagnosis in one sentence? Do they know the names of their medications and what they treat? Can they describe a symptom change to a provider who doesn't know their history?

Adult medicine assumes patients can answer all three. If your young adult can't yet, start now.

At the next appointment, ask your pediatrician to speak directly to your child, even if you're translating or filling in gaps. Hand over responsibility for small tasks: calling in a prescription refill, scheduling the next appointment, keeping a medication list updated in their phone. The goal isn't independence for its own sake. It's readiness for a system that won't make the accommodations your pediatrician made automatically.

Teaching self-advocacy is a years-long process. You're not trying to make your 15-year-old fully independent by 18. You're giving them the building blocks so they can participate in their own care, with whatever level of support they need.

At 14 to 16: Ask Your Pediatrician About Transition Planning

Most pediatric clinics don't bring up transition until you're already 19 or 20. That's too late.

At your next appointment, ask: "What is your transition planning process, and when does it start?"

If the answer is vague or "we'll handle that when the time comes," bring up the Got Transition Six Core Elements framework. This is a federally funded set of operational steps that improve outcomes when implemented early. Your pediatrician should know it. If they don't, you're introducing it now.

The six elements are:

1. A written transition policy stating when planning starts
2. Tracking which patients are approaching transition age
3. Assessing transition readiness
4. Creating a written transition plan
5. Transferring a medical summary to the adult provider
6. Confirming the adult provider received records and completed an introductory visit

You're not demanding all six steps happen tomorrow. You're establishing that transition is on the agenda, and you expect a plan before your child turns 18.

At 17 to 18: Build the Portable Medical Summary

Adult providers don't have time to read 15 years of pediatric records. They need a one-page summary they can skim in 90 seconds before walking into the exam room.

Your pediatrician should provide this as part of the transfer process. If they don't, you create it yourself.

Here's what goes in it, in priority order:

1. Primary diagnosis and date of onset: "cerebral palsy, diagnosed at 18 months" or "Down syndrome, diagnosed at birth"
2. Current medications and dosages: exact names, not brand/generic confusion
3. Baseline functional abilities: mobility, communication, activities of daily living
4. Surgical history: dates and procedures
5. Current specialists and contact information: who else is on the care team
6. Allergies and adverse reactions: drug allergies, environmental triggers, documented side effects
7. Communication needs: "uses AAC device" or "prefers yes/no questions" or "needs extra time to process"
8. Emergency contacts: parent, guardian, or primary caregiver with decision-making authority

That eighth field is critical when emergency treatment requires consent. If your young adult can't provide it, the adult provider needs to know who can.

Keep this document updated. Save it as a PDF. Email it to yourself. Print three copies and keep one in your wallet. You'll bring it to every first appointment with every new provider.

At 17 to 18: Start the Provider Search Early

Don't wait until your child ages out of pediatric care to start looking for adult providers. Start two to three years before the transition.

Ask your pediatrician for referrals. Ask other families in condition-specific support groups who they see. Look for family medicine doctors or internists who explicitly state they serve adults with developmental disabilities.

Some large health systems now have dedicated "transition clinics" that bridge pediatric and adult care. These clinics see patients aged 18 to 25 and coordinate the handoff. If your area has one, get on the list early. Wait times can run six months or longer.

If your young adult has complex medical needs and sees multiple specialists, you need to plan each transition separately. A primary care provider coordinates overall care, but if your child sees a cardiologist, orthopedist, or neurologist, those adult counterparts need to be identified now.

Once you have names, try to establish the relationship before the transfer. Some transition clinics allow "shadow" appointments where the adult provider meets your child while the pediatrician is still managing care. If your clinic doesn't offer this, schedule the first adult appointment for age 19 or 20, overlapping with pediatric coverage. The goal is familiarity before the safety net disappears.

What to Look for in an Adult Provider

Not every adult doctor has experience treating people with lifelong developmental disabilities. Some will tell you that directly. Others will accept your child as a patient and then struggle.

When you call to inquire, ask:

• Do you currently treat adults with [specific condition]?
• How many patients in your practice have developmental disabilities?
• Do you coordinate with specialists, or does that fall to the family?
• What is your communication preference if my child needs accommodations during appointments?

If the answer to the first question is "no" or "I'd be willing to try," keep looking. You want a provider who already has a patient base with similar needs, not someone who's learning on your child.

If you call ten providers and all of them say they don't take new patients with complex needs, you're not failing. The system is failing. Document every call. That documentation may be useful later if you need to appeal an insurance denial or file a grievance about access to care.

At 19 to 21: Manage the Insurance Transition

At 21, many young adults lose Medicaid eligibility tied to their parents' household income. CHIP coverage ends. If your child qualifies for Supplemental Security Income (SSI) as an adult, Medicaid eligibility may continue, but the application process takes months and you need to start it early.

Apply for SSI at least six months before your child turns 21 if they're likely to qualify. The application requires medical records, functional assessments, and documentation of how the disability limits work. Start gathering those documents at 20, not 20 and a half.

If your child doesn't qualify for SSI, check whether your private insurance allows dependent coverage until age 26 under the Affordable Care Act. Most plans do, but the benefits may shift once your child ages out of pediatric-specific services. Call your insurer and ask which adult providers are in-network and whether prior authorizations will be required for medications and therapies that moved automatically under pediatric care.

Plan for a coverage gap. Not every family hits one, but many do. If your child's Medicaid ends before SSI is approved, or if your private insurance drops coverage for a medication an adult provider prescribes, you need a backup plan. Ask your pediatrician whether they can write a 90-day supply of maintenance medications before the transition so you have a buffer.

The Transfer: What Happens at the First Adult Appointment

Bring the portable medical summary. Bring a list of current medications with dosages. Bring a parent or support person if your young adult wants one.

The first appointment with an adult provider is not a full physical. It's an introductory visit. The goal is to establish the relationship, confirm the provider received records from your pediatrician, and set up a care plan moving forward.

If the provider didn't receive the records, that's a system failure but not a crisis. Hand them the medical summary you created, which covers diagnosis, medications, baseline functional abilities, surgical history, current specialists, allergies, communication needs, and emergency contacts.

Watch how the provider interacts with your young adult. Do they address your child directly, or do they talk to you as if your child isn't in the room? Do they ask accommodating questions, or do they assume cognitive limitations based on diagnosis? Do they listen when your child describes a symptom, or do they dismiss it?

These are the signals that tell you whether this provider is the right fit. One awkward appointment doesn't disqualify someone. A pattern of dismissiveness does.

If the first provider doesn't work out, go back to your list and try the next one. You're not locked in. Adults with disabilities can and should advocate for themselves when a provider isn't meeting their needs.

When the System Doesn't Show Up

Not every area has adult providers trained in neurodevelopmental disabilities. You may request transition planning at 14 and hear nothing until 20. You may call every provider on your insurance list and get turned away.

When that happens, you build your own bridge.

Ask your pediatrician if they can extend care to age 22 or 23. Some states allow it. Others don't, but it's worth asking.

If you can't find an adult primary care provider with disability experience, look for one willing to learn. Bring the medical summary. Be prepared to educate. It's not fair, but it's reality for many families. A provider who listens and coordinates care is better than a specialist who doesn't return calls.

Some families continue seeing pediatric subspecialists (cardiologists, orthopedists, neurologists) into adulthood because those doctors know the condition and adult counterparts don't exist or won't take new patients. If that's your situation, you're not failing. You're navigating the gap the system created.

What to Do This Week

If your child is between 14 and 21, start the portable medical summary. Open a document and fill in the eight fields listed above. You won't have every piece of information yet. That's fine. Start with what you know, and add to it at every appointment.

If your child is under 14, save this article. You'll need it in a few years.

If your child is over 21 and you're reading this after the transition already happened, the same principles apply retroactively. Create the summary now. Identify providers now. The work of building a stable adult care team starts whenever you start it.

The gap at 21 is real. The earlier you start preparing, the less disruptive it is when it arrives.
