Medicare in Georgia

Medicare beneficiaries can choose to get their Part A and Part B coverage through private Medicare Advantage plans, or directly from the federal government via Original Medicare.

Medicare Advantage plans are offered by private insurers and plan availability varies from one county to another. For example, in some Georgia counties, there are only 20 Medicare Advantage plans available in 2024, whereas in other counties there are more than 50 plans.²

Medicare Advantage enrollment had increased to 55% of the state’s Medicare population by July 2024, where about 1,069,003 Georgia Medicare beneficiaries had Medicare Advantage coverage¹ (not counting people with private coverage like Part D and Medigap, used to supplement Original Medicare).

About 865,913 Georgia Medicare beneficiaries had coverage under Original Medicare instead at that point.¹

Original Medicare does not limit out-of-pocket costs (like monthly premiums and coinsurance or copayments), so most enrollees maintain some form of supplemental coverage.⁶

Nationwide, over 80% of Original Medicare beneficiaries have supplemental coverage. But for those who don’t, Medigap plans (also known as Medicare Supplement Insurance plans, or MedSupp) will pay some or all of the out-of-pocket costs (e.g., deductibles and coinsurance) they would otherwise have to pay if they only had Original Medicare coverage.⁷

Medigap plans are sold by private insurers, but they’re standardized under federal rules and regulated by state laws and insurance commissioners. There are 39 insurers that offer individual Medigap plans in Georgia in 2025.⁸ Details about the insurers that offer Medigap plans in Georgia are available through the Plan Finder tool on the Medicare.gov website.

There are three ways Medigap insurers can set their premiums: Issue-age rating means that premiums are based on the age the person was when they enrolled in the plan, so a person who enrolls at age 65 will always pay a lower premium than a person who enrolls at age 80 (rates can still increase overall, but not based on a particular enrollee’s increasing age). Attained-age rating is the approach that most insurers use nationwide (except where prohibited), and it allows the insurer to increase premiums based on the enrollee’s current age, so rates go up as a person ages. Community rating means that premiums don’t vary with age, but there are only eight states that require this approach, and insurers usually do not use it if not required to do so.⁹

In Georgia, Medigap insurers have been prohibited from using attained-age rating for plans issued since 2009 (see Section 7). So most Medigap plans in the state use issue-age rating, ¹⁰although some opt for community rating.

Federal rules require Medigap insurers to offer plans on a guaranteed-issue basis during an enrollee’s open enrollment period, which begins when the person is at least 65 years old and enrolled in Medicare Part B (and Part A; you have to be enrolled in both to obtain Medigap, but some people delay enrollment in Part B if they continue to receive employer-sponsored coverage to supplement Medicare Part A). Despite the fact that over 7 million Medicare beneficiaries nationwide are not yet 65,​​¹¹​​ there is no federal requirement that Medigap insurers offer plans to people who are under age 65.¹² However, the state of Georgia does require insurers to offer Medigap to those under 65.¹⁰

But the majority of the states have addressed this with legislation that ensures at least some access to Medigap plans for people under age 65, and Georgia is among them. In Georgia, Medigap insurers must offer their plans on a guaranteed-issue basis to anyone who enrolls in Medicare Part B, regardless of age.¹⁰ This rule took effect in 2011, and Georgia granted a one-time six-month open enrollment period to people who already had Part B; since then, people who enroll in Medicare in Georgia all have the same six-month open enrollment period for Medigap, regardless of their age.

Georgia’s statute clarifies that people under age 65 can be charged higher premiums, but that the premium variation “shall not be excessive, inadequate, or unfairly discriminatory and shall be based on sound actuarial principles and reasonable in relation to the benefits provided.”¹⁰ Even with that parameter, Medigap rates are substantially higher for Georgia residents under the age of 65; rate filings are available in SERF and on Medicare’s plan finder tool. Most Georgia Medigap insurers are charging under-65 enrollees between three and ten times as much as they charge enrollees who are 65.¹³

Disabled Medicare beneficiaries have access to another Medigap open enrollment period when they turn 65. At that point, they can obtain a plan with the standard age-65 rates.

Disabled Medicare beneficiaries have the option to enroll in a Medicare Advantage plan instead of Original Medicare, and rates are not higher for enrollees under age 65. Medicare Advantage plans have more limited provider networks than Original Medicare, and total out-of-pocket costs can be as high as $8,300 per year for in-network care, plus the out-of-pocket cost of prescription drugs (Part D does not have a cap on out-of-pocket costs, regardless of whether it’s purchased as a stand-alone plan or integrated with Medicare Advantage) can be higher.¹⁴

Although the Affordable Care Act eliminated pre-existing condition exclusions in most of the private health insurance market, those rules don’t apply to Medigap plans. Medigap insurers can impose a pre-existing condition waiting period of up to six months if an individual didn’t have at least six months of continuous coverage prior to your enrollment (although many of them choose not to do so). And if you apply for a Medigap plan after your initial enrollment window closes (assuming you aren’t eligible for one of the limited guaranteed-issue rights), the Medigap insurer can consider your medical history in determining whether to accept your application, and at what premium.

Original Medicare does not provide coverage for outpatient prescription drugs. Over 80% of Original Medicare beneficiaries have some type of supplemental coverage, and these plans can include prescription drug coverage.⁶¹⁵

Medicare Part D, created under the Medicare Modernization Act of 2003, provides drug coverage for Medicare beneficiaries who do not have another source of coverage for prescription drugs expenses. Medicare Part D coverage can be purchased as a stand-alone plan (called a prescription drug plan, or PDP) or obtained as part of a Medicare Advantage plan. (Medicare Advantage plans with built-in prescription drug coverage are called Medicare Advantage-Prescription Drug, or MAPD, plans).

You can sign up for a PDP or MAPD (or change to a different one) during the annual enrollment period that runs from October 15 to December 7 each year, with the new coverage effective January 1 of the coming year.

There are 16 stand-alone Medicare Part D plans for sale in Georgia in 2025, with premiums that start at $0 per month.³

Overall Medicare Part D enrollment — including stand-alone prescription drug plans and Medicare Advantage plans with integrated Medicare Part D prescription drug coverage — has been steadily increasing in Georgia¹⁶¹⁷ as overall Medicare coverage enrollment has grown. But enrollment in stand-alone Medicare Part D plans has been decreasing in Georgia, because Medicare Advantage enrollment growth has outpaced Original Medicare enrollment growth.

As of July 2024, there were 524,870 Georgia residents with stand-alone Medicare Part D plans.¹ That was down from more than 627,566 in March 2018.¹⁶ But during the same period, enrollment in Medicare Advantage plans with integrated Part D coverage had grown from about 620,828 people¹⁶ to more than 1,022,907 people.¹

Many Medicare beneficiaries receive financial assistance through Medicaid with the cost of Medicare premiums, prescription drug expenses, and services not covered by Medicare – such as long-term care.
