What are Medicare Advantage and Original Medicare?

Original Medicare (Parts A and B)

Original Medicare (Parts A and B) is a U.S. government health insurance program for individuals 65 and older, as well as individuals who qualify for disability.

  • Medicare Part A is hospital insurance that covers inpatient services. Premiums may not apply for those who have worked for at least 10 years, paying Medicare taxes. Deductible and coinsurance/payments may also apply.
  • Medicare Part B is medical insurance that covers preventative services, doctor visits, lab tests, durable medical equipment and other medically necessary services. Monthly premiums usually apply, and deductible and 20% co-insurance apply for most services.

Both Parts A and B come directly from the government.

You may choose to obtain Parts A and B benefits through Medicare Advantage plans offered through private insurers.

Medicare Advantage (Medicare Part C)

Medicare Part A and Part B benefits are also provided through private insurance companies that are contracted by Medicare.

Individuals are still in the Original Medicare program so premiums for Part B still apply.

However enrollment in a Medicare Advantage plan requires self registration during open enrollment periods.

Medicare Advantage Enrollment Options

  • An Initial Enrollment Period for Medicare Advantage applies within the first 7 months of Original Medicare eligibility.
  • The Annual Election Period (AEP) also known as "Fall Open Enrollment", occurs every year from October 15 to December 7. You can switch between different plans and/or change coverage options during this period.
  • A Special Enrollment Period (SEP) allows you to qualify under specific circumstances. These typically apply to loss of coverage such as losing employer-based health insurance. Individuals can check eligibility for SEP by contacting Medicare at Medicare.gov or 1-800-MEDICARE (633-4227); TTY users, call 1-877-486-2048; 24/7.
  • Individuals enrolled in Medicare Parts A and B and who live in the plan's service area.
  • Individuals with end-stage renal disease such as permanent kidney failure - call the plan to confirm eligibility. In this case, you may qualify under the Special Needs Plan.
