Copy-pasting a post from that thread that may be pertinent:
"Perfectly usual in the States for young adults to be treated at Children’s Hospitals.
For some really rare conditions people remain with a paeds specialist their whole life as there isn’t an adult service to transition to, but that’s fairly unusual. As a result of that kind of need, however, Boston Children’s now run a clinic for adults - of any age - with congenital heart disease: mostly they’re lifelong BCH patients, but they’ll accept anyone with a qualifying condition.
The transition/turfing out point now is generally between 21 & 26 (latter is when children stop being covered by their parents’ insurance). Lots of people with health conditions requiring hospital care choose to remain with existing consultants/care teams during their undergraduate degree (if they do one) so they’re not making loads of big life changes at once (& you can’t move to adult services before 18) but you do see a certain sort of profile on social media clinging to paeds teams (including their paediatricians) for as long as possible.
BCH’s main cut-off age for treatment is 21. They do run a couple of adult clinics (eg the cardiology one I mentioned earlier) - but they’re for adults who will have spent significant amounts of their childhoods & adolescences in hospital; & who will continue to need regular hospital treatment for the rest of their lives.
BCH offering these surgeries to people in their thirties is absolutely about making as much money as possible from this particular revenue stream. Because, let’s face it, the 35 year olds won’t be patients of 33 years standing, or even 15.
While there are of course always questions in the US about negotiating insurance coverage, why an adult would seek treatment at a children’s hospital they didn’t have a long-standing relationship with raises troubling questions. In their early twenties it could well be someone who’d begun transitioning in their late teens via BCH. Any older & it seems a deeply problematic choice."
