Here's why we're building the healthcare handoff for ages 18–26." date: 2026-03-20 authors: ["Katie Robinson", "Christian Robinson"] slug: why-we-built-lineage source: https://lineagehealth.co/#/blog/why-we-built-lineage site: Lineage Health --- # Why We Started Lineage Health: The Healthcare Handoff Nobody Talks About By **Katie Robinson** & **Christian Robinson** — March 20, 2026 **Christian turned 26 and lost his health insurance overnight.** Coverage ended at the end of the month. Nobody walked him through what came next. He spent four months figuring out the Marketplace, COBRA, and employer plans on his own. In the gap, he stopped going to the doctor. A year later, Katie was a junior at Harvard when her prescription ran out. The pharmacy needed a new authorization. The doctor was in another state. The insurance card was a photo on her mom's phone from 2017. It took three weeks to get a single refill. Neither story was an emergency. Neither was unusual. Every young adult we know has a version of it — because young adults are the worst-served age group in American healthcare. ## Young adults have it worst — and the data is clear Healthcare is hard for everyone. But the research shows young adults face it without the tools, the experience, or the system support that other age groups have. - Young adults ages 18–24 are **151% more likely** to have inadequate knowledge of basic health insurance terms than adults 44–64.[^1] - They are **44% more likely** to lack confidence using their health insurance to access care.[^1] - They have the **highest uninsured rate** of any age group — about 30%, more than triple the rate among children.[^2] - They are the **most likely to be uninsured** AND least likely to report a usual source of medical care than any other age group.[^3] - Only **16% of all U.S. adults** can calculate their out-of-pocket costs under their own insurance plan — and young adults score lower than every other age cohort.[^4] Worse still, the assumption that young adults are "young and healthy" doesn't hold up. One in six young adults has a chronic illness like cancer, diabetes, or asthma.[^2] And 48% of uninsured young adults report problems paying medical bills.[^2] The picture is grim: the age group with the highest uninsurance rate, the lowest health insurance literacy, the fewest established doctor relationships, and the least experience navigating the system — is also the group quietly carrying chronic conditions and walking off the edge of a parent's plan at 26 with no handoff. ## Why young adults are uniquely unequipped Most age groups grew into the system. They've spent decades calling member services, reading EOBs, filing claims, choosing plans, arguing with billing departments. The vocabulary is familiar. The muscle memory is real. Young adults have none of that. The insurance card lives in a parent's wallet. The deductible was set in October by someone else. The pediatrician's portal uses a parent's email. The records stop at a 12-year-old's checkup. When something goes wrong, the young adult calls home. That's not weakness. That's the system working exactly as designed — to be navigated by parents. Then at 26, the system flips. The parent is removed. And nobody trained the young adult for the version of healthcare they now have to use. > "Even with insurance, it is still hard to access healthcare. It is so complicated and you don't really learn in school how to navigate it." > > — Young adult, quoted in NIH report on young adult healthcare access[^5] ## The cost is bigger than missed appointments Low health literacy in general costs Americans up to **$238 billion every year** in unnecessary healthcare spending — between 7% and 17% of all personal healthcare expenditures.[^6][^7] For young adults, the cost compounds in a way that's particularly damaging. The years between 18 and 26 are when adult health habits form. When chronic conditions are first diagnosed and managed. When preventive care patterns get set for life. A young adult who skips care during this window doesn't just lose access to one appointment — they lose the foundation of how they'll engage with healthcare for the next 50 years. - Limited health literacy is linked to more hospitalizations, more ER use, lower preventive screening, and worse medication management.[^8] - People with low health literacy are **diagnosed later**, when illness is harder to treat.[^9] - University students with low health literacy show worse preventive care patterns, riskier health habits, and lower wellbeing.[^10] - Patients with inadequate health literacy are **three times more likely** to return to the ER within 90 days of a hospital discharge.[^11] A skipped refill becomes a flare-up. A flare-up becomes an ER visit. An out-of-network urgent care becomes a $487 bill. A missed screening becomes a problem caught too late. None of it looks catastrophic in the moment. All of it compounds — and for young adults, it compounds across the longest healthcare runway any age group has. ## The handoff doesn't exist At 18, HIPAA cuts parents off from a young adult's medical records. At 26, the young adult is cut off from their parent's plan. Between those two moments, there's no system that moves the knowledge from one to the other. No portal. No document. No checklist. Just a pediatrician's office that says "good luck" and a benefits PDF nobody reads. The entire system rests on a parent's memory and a phone call. Today's consumer health tools weren't built for this. Records platforms store data but don't help you act on it. Telehealth apps deliver care but don't navigate insurance. Care navigation services serve employers and Medicare — not young adults aging out of family coverage. Nobody is building the handoff itself. So we are. ## Why we're building this We're building Lineage Health because we lived this problem — and because almost every young adult we know has lived a version of it too. Christian's four months without coverage. Katie's three weeks to refill a prescription. The friend who got hit with a $1,200 ER bill because she didn't know her plan had changed. The friend who skipped therapy for a year because she couldn't figure out what was in network. The friend who turned 26 and just stopped going to the doctor, full stop. The friends who still call their parents every single time something goes wrong. These are not edge cases. These are the default experiences of being a young adult in American healthcare today. And the more young adults we talked to, the clearer it became: this isn't a problem of laziness or apathy or being "bad with adult stuff." It's a problem of design. The system was never built for young adults to navigate alone, and nobody ever taught them how. So we want to fix it. We want healthcare to be easier to navigate at the exact moment it becomes hardest — the transition from parent-managed to independent care. We want a 19-year-old to be able to look up her own insurance card without texting her mom. We want a 24-year-old to know which urgent care near him is in network before he needs it. We want a 26-year-old to walk off a parent's plan with a real plan of his own, not four months of confusion and a stack of unopened bills. That's the bar. Healthcare should be easier to navigate. For us. For our friends. For every young adult who's been told to figure it out alone. ## What Lineage Health does Lineage Health is a healthcare handoff platform for young adults ages 18–26 and their parents. It works in three steps. **1. Connect.** A parent extends a view of their insurance and records to the young adult — like adding an authorized user to a credit card. The young adult finally has visibility into the plan they're already on. **2. Capture.** The parent shares the context only they know: family history, childhood vaccines, allergies, medications, the doctors who saw their kid grow up. The information that's always lived in a parent's head finally lives somewhere else. **3. Decide.** Lineage Health surfaces the next decision at the right moment. The refill before it runs out. The in-network doctor near campus. The plan choice at 26. The appointment that's been on the to-do list for six months. Two phones, not one. The parent has their portal. The young adult has theirs. Over time, the young adult's fills in and the parent's steps back. > The handoff is the product. The problem was never access to insurance. It's ownership of health. Young adults are uninsured at higher rates than any other age group. They're the least confident, the least equipped, and the least supported. And they're inheriting a system that wasn't designed for them. That moment of inheritance doesn't have to look like Christian's four-month gap. Or Katie's three-week refill. With the right handoff, it can look like a normal transition into adulthood — which is what it should have been all along. --- *Lineage Health is the handoff platform for young adults 18–26 and their parents.
