This assumes that all current clinics and hospitals would remain ‘operational’. I don’t see that happening if you go to Medicare-for-all.
If you drew a 25-mile circle around your house on day one, with four public hospitals and ten public clinics...the dynamics would change within three years. Most of the clinics would downsize and only handle certain issues. At least one of the hospitals would shutdown entirely because of the limit on profits. Cancer-treatment? You might find one single option within fifty miles of your home.
The cost would rapidly decrease as the units downsize or limit their ‘products’. You’d finally get affordable care...but find that it’s marginal care at best.
You’d also have to force doctors and nurses and specialists to accept Medicare-based wages. And that will never happen, not with the cost of being educated and maintaining certification in those specialties. What you’ll end up with is boutique care, closed private practices where doctors pick and choose their clientele. And, you’d have to indemnify the hospitals from lawsuits because they won’t be able to afford them. Regional centers with long waiting lists staffed by imported PAs of questionable training will take care of the ‘little people’ - the equivalent of nursing home level care.
I take that back, there are quite a few vets.
#3, and have to wait 6-9 months to get it.
