Medicare enrollment in Louisiana

As of early 2022, there were 897,889 residents enrolled in Medicare in Louisiana. That was about 19% of the state’s population and roughly the same as the percentage of the total U.S. population with Medicare coverage enrollment.

For most Americans, Medicare benefits come with turning 65. But Medicare eligibility is also triggered for younger people if they’re disabled and have been receiving disability benefits for 24 months, or are diagnosed with ALS or end-stage renal disease.

In Louisiana, about 17% of Medicare beneficiaries are under the age of 65, versus a nationwide average of less than 13%.

Medicare options

When a person becomes eligible for Medicare, they can choose between Medicare Advantage plans, where coverage is through private health insurance companies, or Original Medicare, where medical claims are paid directly by the federal government. Original Medicare beneficiaries also have options around Medigap policies and Medicare Part D (prescription drug) coverage.

Original Medicare includes Part A (also called hospital insurance), which helps pay for inpatient stays at a hospital, skilled nursing facility, or hospice center, and Part B (also called medical insurance), which helps pay for outpatient care like physician services, kidney dialysis, outpatient surgeries, physical therapy, preventive health care, and durable medical equipment.

Medicare Advantage plans include all the coverage of Parts A and B, although cost-sharing amounts (deductible, coinsurance, copays) can be very different. Advantage plans usually include extra benefits, such as Part D prescription drug coverage and dental and vision coverage. But Advantage plans also tend to have limited provider networks and higher out-of-pocket costs than a person would have if they enrolled in Original Medicare plus a Medigap plan. There are pros and cons to either option, and the “right” solution is different for each individual.

Medicare’s annual election period (October 15 to December 7 each year) allows Medicare beneficiaries the chance to switch between Medicare Advantage enrollment and Original Medicare (and add, drop, or switch to a different Medicare Part D prescription plan). And beneficiaries who are already enrolled in Medicare Advantage plans also have the option to switch to a different Medicare Advantage plan or to change to Original Medicare during the Medicare Advantage open enrollment period, which runs from January 1 to March 31.

Medicare Advantage in Louisiana

Private Medicare Advantage plans are available throughout Louisiana. Every parish in Louisiana has at least 23 Medicare Advantage plans available for 2022, and as many as 52 plans are for sale in East Baton Rouge Parish.

34 percent of the state’s Medicare beneficiaries were enrolled in Medicare Advantage plans as of 2018, which was the same as the percentage of Medicare beneficiaries with Medicare Advantage plans nationwide. As of January 2022, private Medicare enrollment in Louisiana stood at 448,678 people, 449,211 had Original Medicare. So by that point, Medicare enrollment in Louisiana was split nearly equally between Medicare Advantage and Original Medicare.

Medigap in Louisiana

Original Medicare does not limit out-of-pocket costs (i.e., deductible and copay), so most enrollees maintain some form of supplemental coverage. More than half of Original Medicare beneficiaries get their supplemental coverage through an employer-sponsored plan or Medicaid.

But for those who don’t, Medigap plans (also known as Medicare supplement plans) will pay some or all of the out-of-pocket costs they would otherwise have to pay if they had only Original Medicare. According to an AHIP analysis, 154,227 Louisiana Medicare beneficiaries had supplemental coverage under Medigap plans as of 2020.

Medigap plans are sold by private insurers, but the plans are standardized under federal rules. There are ten different plan designs (differentiated by letters, A through N), and the benefits offered by a particular plan (Plan G, Plan N, etc.) are the same regardless of which insurer sells the plan.

There were 35 insurers that offered Medigap plans in Louisiana when the state published its most recent Medigap shopping guide in 2017. As of 2022, Medicare’s plan finder tool showed 37 Medigap insurers offering plans in the state. Medigap insurers in the state are required to maintain minimum loss ratios of at least 65% for individual policies, and at least 75% for employer group policies. This means that at least 65% (or 75% for group plans) of the premium revenue that the insurers bring in must be spent on enrollees’ medical claims.

Unlike other private Medicare coverage (Medicare Advantage and Medicare Part D plans), there is no annual open enrollment window for Medigap plans. Instead, federal rules provide a one-time six-month window when Medigap coverage is guaranteed-issue. This window starts when a person is at least 65 and enrolled in Medicare Part B (you must be enrolled in both Part A and Part B to buy a Medigap plan).

People who aren’t yet 65 can enroll in Medicare if they’re disabled and have been receiving disability benefits for at least two years, and 17% of Louisiana Medicare beneficiaries is under age 65. Federal rules do not guarantee access to Medigap plans for people who are under 65, but the majority of the states have implemented rules to ensure that disabled Medicare beneficiaries have at least some access to Medigap plans. Louisiana is among them, although the state’s 2017 Medigap guide indicated that was a fairly recent development in the state.

In Louisiana, disabled Medicare beneficiaries under the age of 65 have the same six-month open enrollment period for Medigap plans as a person who becomes eligible for Medicare in Louisiana due to age. But premiums are dramatically higher for enrollees under the age of 65 (in most cases, several times higher: 2022 premiums for Medigap Plan A for a 65-year-old Louisiana male range from $75 to $280/month; for a 45-year-old male, they range from $260 to $1,000/month). People who are enrolled in Medicare prior to age 65 have another Medigap open enrollment period when they turn 65. At that point, they can switch to a plan with the lower premiums that apply to people who are aging into Medicare, rather than qualifying due to disability.

Disabled Medicare beneficiaries can opt for Medicare Advantage instead (this includes beneficiaries with kidney failure, who were generally unable to join Medicare Advantage plans prior to 2021). Medicare Advantage plans are otherwise available to anyone who is eligible for Medicare, and the premiums are not higher for those under 65. But as noted above, Advantage plans have more limited provider networks than Original Medicare, and total out-of-pocket costs can be as high as $7,550 per year for in-network care, in addition to prescription drug costs.

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 you didn’t have at least six months of continuous coverage prior to your enrollment. 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.

Louisiana Medicare Part D

Original Medicare does not provide coverage for outpatient prescription drugs. More than half of Original Medicare beneficiaries have supplemental coverage via an employer-sponsored plan (from a current or former employer or spouse’s employer) or Medicaid, and these plans often include prescription coverage.

But Medicare beneficiaries who do not have drug coverage through Medicaid or an employer-sponsored plan need to obtain Medicare Part D in order to have coverage for prescriptions. It can be purchased as a stand-alone plan, or as part of a Medicare Advantage plan with integrated Part D prescription drug coverage.

There are 20 stand-alone Medicare Part D plans for sale in Louisiana for 2022, with premiums that range from under $7 to $101/month.

292,363 beneficiaries of Medicare in Louisiana — about a third of the state’s total Medicare population — had prescription coverage under stand-alone Medicare Part D plans as of early 2022. But a larger population — 428,654 beneficiaries — had Medicare Part D coverage integrated with their Medicare Advantage plans. As Advantage enrollment has grown in Louisiana, enrollment in stand-alone Part D plans has dropped, since most Advantage plans have integrated Part D coverage.

Medicare Part D enrollment follows the same schedule as Medicare Advantage: Beneficiaries can pick a Medicare Part D plan when they’re first eligible for Medicare, and they can switch plans during the annual open enrollment period in the fall, from October 15 to December 7, with coverage that takes effect the following January.

How does Medicaid provide financial assistance to Medicare beneficiaries in Louisiana?

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