 Medical coverage. Say that 10 times. Medical coverage with Medicare. I'm not going to even try. Each plan offers unique features, benefits, copay and coinsurance structures, and maximum out-of-pocket limits to keep the budget for seniors in full focus. Plans may offer some extra benefits that Original Medicare doesn't cover, like vision, hearing, and dental services. The other way to utilize your insurance with your Medicare is your Medicare Supplement Plan, which is also known as a Medigap.
