There is no one "best" medical insurance for senior citizens. However, there are a few factors to consider when choosing a plan. First, decide if you want Original Medicare (Parts A and B) or a Medicare Advantage Plan (Part C). Original Medicare is run by the federal government, while Medicare Advantage Plans are offered by private companies.
If you choose Original Medicare, you may also want to purchase a separate Part D plan for prescription drug coverage. Alternatively, some Medicare Advantage Plans include prescription drug coverage.
Once you've chosen your plan, compare the costs of the various options. You will want to consider the monthly premium, as well as any deductibles, copayments, or coinsurance. You may also want to consider the provider networks of the various plans, as well as any extra benefits they offer.
To help you compare the various options, you can use the Medicare Plan Finder tool on the Medicare website.
