I have permanent residency in Taiwan so it's easy for me, although before that it was still easier than anything in the US, just not next to free without their national insurance.

I don't necessarily encourage medical tourism but simply fly to Taipei, find a doctor you want to see, and sign up for an appointment. It will be a little more work without the NHI card but still probably less than whatever you're dealing with. If you get medical scans, almost everyone can print a CD with them in a day or two if you ask. Getting care even without insurance was cheaper than just my US insurance premiums.

Having someone fluent in Chinese is important enough I'd say it was required but if you restrict yourself to a smaller sunset of hospitals and clinics that serve foreigners around like Tianmu you may be able to get by with a translator app.

People outside NHI are uncommon and their medical system isn't really set up to support it. You may want to consider actual medical tourism facilities of which I've heard of several in Mexico or Costa Rica.

You and your mother may also want to consider rioting, because the US system is deliberately and almost uniquely stupid.
