(op here) The premise of the grandparent is an illusion that depends on the idea that somehow a medical provider (which one?) is a better caretaker for your medical history than you are. In the cases where that is actually true, power of attorney is the real solution -- not EMR records hosted offsite by 3rd party vendors in 3rd world countries on behalf of one or more hospitals. How absurd.

My medical history is mine; it's ultimately not yours. If you need my medical history, allow me to give you limited access to it.

Now, if your billing is opaque and you're playing shenanigans with the insurance companies about who owes what, then sure, you need my Passport, SSN, DNA, Real ID, and biometrics -- and you should probably hold my medical history hostage too -- to make sure that you can collect on the debt.
