As far as I know, Medicare only provides insurance for people over 65 and people with disabilities. You can use any private company's insurance, right? There's no problem with that. But you have to pay more. My employer provided me with insurance. I work in a pharmacy, so there's nothing strange about that. Pharmacies have their own insurance companies, intermediaries (I see about the existence of intermediaries recently here [hg.org]. Honestly, I don't understand much about it. Hopefully, with time I will be able to figure it out.

All hospitals and clinics in the United States are run as for-profit structures. Insurance companies are the bridge between patients and hospitals. They can also negotiate the prices of medical services. In conclusion, if you have health insurance, you can benefit from cheaper services. But if you go to the hospital without insurance, you pay the default price. The most helpful thing in the USA is to work for a company that offers medical insurance, but dental and vision insurance are separate, as they have an annual limit.

When choosing your medicare plan, it is important to know what is covered and what isn’t. There are so many different plans for Medicare, that it can be confusing to know which plan will give you the best coverage. Medicare Part A covers hospital inpatient costs when you are formally admitted to a hospital with a doctor’s order. Medicare Part B covers your doctor’s services and preventive healthcare, such as yearly doctor visits and tests. Medicare Part C is privately sold insurance options that include the same coverage as parts A and B in addition to extra benefits like prescription drug plans, dental, hearing, vision, and others. Medicare Part D is the plan that covers prescription drugs not covered by Part B, which are typically the kind of medications that need to be administered by a doctor, like an infusion or injection.
