Does Medicare pay for all of my health care?

No. Medicare only pays for covered goods and services. In fact, there are many co-pays and deductibles. The 2016 co-pays are at the following link: https://www.medicare.gov/your-medicare-costs/costs-at-a-glance/costs-at-glance.html. The 2017 numbers have not been finalized yet, but when they are, they should be posted at the same link. Most individuals who purchase a Medicare Supplement will have the co-pays and deductibles covered by the supplement. You can learn more about Medicare Supplements at https://www.medicare.gov/supplement-other-insurance/medigap/whats-medigap.html

Where can I learn more about what’s covered and what’s not covered?

The best place to start is with the annual Medicare & You booklet. The 2017 version is at the following link: https://www.medicare.gov/pubs/pdf/10050-Medicare-and-You.pdf
