BUT.
I have a hard time thinking of getting a doctor's appointment in 20 days as "incredible access." If I need to see a doctor, I can get an appointment at the local clinic within a day or two. And my employer-provided health insurance is pretty crappy! If I tell the clinic I think it's important (like I'm in pain but it's not an emergency), they'll try to fit me in the same day if possible.
And that's not even considering the Urgent Care facilities 15 miles away..
According to kaitai, those "20 days" are the absolute upper boundary. As a German, I don't find that upper boundary particularly high. When I need to see a specialist about something that's not an emergency, a wait time of a few weeks is normal since there are only so many specialists per area.
There are veterans who are still waiting to get paperwork processed to show a service connection for health issues -- they're still waiting to get into the VA system -- but that's a different bureaucracy. The wait time at most VAs once you're in the system is substantially less than through my employer-provided insurance.
