Medicare and the Affordable Care Act

Last Updated : 07/06/20183 min read

The Affordable Care Act (ACA), also known as Obamacare, has had an impact on the Medicare program.

Early-detection cancer screenings, such as mammograms and colonoscopies, are now covered under Medicare Part B with no out-of-pocket charges if your doctor accepts assignment.

There’s also a yearly “wellness” visit to a physician that is free for Medicare beneficiaries, thanks to the ACA.

The ACA also seeks to close the prescription drug coverage gap (also called the “donut hole”). In the next several years, out-of-pocket costs for drugs are expected to drop, and the coverage gap will close in 2020.

In addition, improved coordination between doctors, hospitals, and insurance companies as mandated by the ACA will ensure that patient information is shared more efficiently to improve care and minimize errors.

Obamacare impact on Medicare Advantage plans

If you are currently enrolled in Medicare, you do not need to enroll in another health plan with the Health Insurance Marketplace, and your Medicare coverage will not be affected by this part of Obamacare. In fact, it’s prohibited for someone to sell you a Marketplace health plan if they know you have Medicare. If you decide to make changes to your Medicare coverage, you will do so during the Medicare Annual Election Period (from October 15 to December 7), not through the Marketplace.

If you have Original Medicare (Part A and Part B), Medicare Part A only, or a Medicare Advantage plan, you meet the Affordable Care Act requirement to have health insurance. However, if you are only enrolled in Medicare Part B, this does not satisfy Obamacare’s minimum essential coverage requirement. You may need to purchase a Medigap policy to supplement your coverage, or you may face a tax penalty.

Do your research:

  • If you are already a Medicare beneficiary, then you do not need to sign up for health coverage under the health-insurance marketplace at
  • Medicare is not part of the ACA marketplace, and the eligibility rules for your health and prescription drug coverage remains the same.
  • Once your Annual Notice of Change arrives in the mail, review it to be sure that your health needs fit what’s included in your Medicare plan so that you aren’t facing out-of-pocket costs in the future.
  • Remember to shop around if you’re thinking about changing your Medicare plan options in the future.
