A whole new government department will need created, staffed.

With state oversight departments.

Billing software will need created unless existing is up to the task. Idk how old it is.

Reviews of hospitals and clinics costs and charges will need reviewed from every location and pricing allowances determined.

A lot of this already exists for Medicaid and Medicare though.

This would honestly take at minimum, 2 years. Even piggybacking from Medicaid/Medicare infrastructure and logistics.

Dental and vision will probably take longer.

But a lot of Medicaid/Medicare current work infrastructure likely needs a huge overhaul. I think there will be a demand to get it going.

It's going to take an enormous amount of planning and human resources, but under the right project planner and good oversight , it can be done. Effeciently.
