Medicare enrollment in Connecticut

As of mid-2020, Medicare enrollment in Connecticut stood at 689,134 people, amounting to about 19 percent of the state’s population. As is the case nationwide, Medicare enrollment in Connecticut is comprised mostly of people who are eligible due to their age (ie, being at least 65). But younger Americans gain Medicare eligibility after they have been receiving disability benefits for 24 months, or have ALS or end-stage renal disease. In Connecticut, 13 percent of beneficiaries are eligible due to disability rather than age (nationwide, it’s 15 percent).

Medicare Advantage in Connecticut

Private Medicare Advantage plans are an alternative to Original Medicare. There are pros and cons to either option, and the right solution is different for each person. Plan availability varies by county, but Connecticut’s Medicare Advantage market is particularly robust, with at least 29 plan options available throughout the state.

Nationwide, 34 percent of all Medicare beneficiaries were enrolled in Medicare Advantage plans as of 2018, although it varied from a low of 1 percent in Alaska to a high of 56 percent in Minnesota. Medicare Advantage enrollment in Connecticut was right on par with the national average, however, with 34 percent of the state’s Medicare beneficiaries enrolled in Medicare Advantage plans.

By mid-2020, however, there were 310,703 Connecticut residents with private Medicare coverage, amounting to more than 45 percent of the state’s Medicare population. A similar trend has been happening nationwide, with increasing Medicare Advantage enrollment every year since 2004. But Medicare Advantage growth in Connecticut has been particularly robust. According to CMS data, nationwide Medicare coverage enrollment increased by a little less than a million people from August 2019 to July 2020, while private Medicare enrollment (almost all of which is Medicare Advantage) grew by about 2 million people. But in Connecticut, from August 2019 to July 2020, the total Medicare population grew by 6,624 people, while the state’s Medicare Advantage enrollment grew by 26,023 people.

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

Medigap in Connecticut

Original Medicare does not limit out-of-pocket costs, so most enrollees maintain some form of supplemental coverage. Nationwide, 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, or MedSupp) will pay some or all of the out-of-pocket costs they would otherwise have to pay if they had only Original Medicare.

There are 14 insurers that offer Medigap plans in Connecticut. And according to an AHIP analysis, 160,799 Connecticut residents had Medigap coverage as of 2018.

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

Prices do vary from one insurer to another, but Connecticut law (Chapter 700c, Section 38a-473) requires insurers to use community rating; rates cannot vary based on age, gender, or health status.

Unlike other private Medicare coverage (Medicare Advantage and Medicare Part D plans), federal rules do not grant an annual open enrollment window for Medigap plans. Instead, federal rules provide a one-time six-month window when Medigap coverage is guaranteed-issue, starting when a person is at least 65 and enrolled in Medicare Part B. But consumer protections are much stronger in Connecticut: All Medigap plans in Connecticut are sold on a guaranteed-issue basis at all times, and with community rating. So Connecticut residents have the option to switch from one Medigap plan to another, regardless of their health.

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 (the 24-month wait does not apply if they have ALS or ends-stage renal disease), and 13 percent of Connecticut Medicare beneficiaries are under age 65. Federal rules do not guarantee access to Medigap plans for people who are under 65, but the majority of the states — including Connecticut — have implemented rules to ensure that disabled Medicare beneficiaries have at least some access to Medigap plans. Connecticut law (Chapter 700c, Section 38a-495c) requires Medigap insurers that offer Plans A, B, and/or C to offer those plans to disabled beneficiaries under age 65.

Connecticut Medicare Part D

Original Medicare does not provide coverage for outpatient prescription drugs. More than half of Original Medicare beneficiaries nationwide 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 Medicare Part D enrollment in order to have coverage for prescriptions. Medicare Part D enrollment is available via stand-alone plans or integrated with Medicare Advantage plans. Part D was created under the Medicare Modernization Act of 2003, which was signed into law by President George W. Bush.

There are 25 stand-alone Medicare Part D plans for sale in Connecticut in 2020, with premiums that range from about $13 to $128/month.

280,651 beneficiaries Medicare in Connecticut had stand-alone Medicare Part D plans as of mid-2020. Another 273,086 of Connecticut’s Medicare beneficiaries had Medicare Part D coverage as part of their Medicare Advantage plans. Stand-alone Medicare Part D enrollment has been decreasing in Connecticut (as has been the case in many states), while enrollment in Part D coverage integrated with Medicare Advantage plans has been increasing. This is due to the increase in the percentage of Medicare beneficiaries — in Connecticut and nationwide — who are choosing Medicare Advantage plans.

Medicare spending in Connecticut

Per-beneficiary spending for Original Medicare in Connecticut was a little higher than the national average in 2018, at $10,729 (the national average was $10,096). The spending amounts are based on data that were standardized to eliminate regional differences in payment rates, and did not include costs for Medicare Advantage.

Per-beneficiary Medicare spending was highest in Louisiana, at $11,932, and lowest in Hawaii, at just $6,971.
