En español | Part B coverage begins after you have paid the 2020 deductible amount of $198 for covered services. Then you usually pay coinsurance of 20 percent of the Medicare-approved amount for each service from a provider who has agreed with Medicare to accept that amount as full payment (also known as Medicare assignment). There is no limit on what you pay in coinsurance in a year.
However, some preventive health services intended to detect and treat problems early are free to Medicare beneficiaries. These services include cancer and cardiovascular disease screenings, glaucoma tests, and flu, hepatitis B and pneumonia shots. (In some instances, you may have to pay a coinsurance or deductible amount.)
Original Medicare does not cover everything. Some items you will have to pay for yourself include hearing aids, most dental care, dentures, cosmetic surgery and acupuncture.
