Extended enrollment opportunity for Californians in areas affected by 2020 wildfires
The annual Medicare open enrollment period for 2021 coverage ended on December 7, 2020.
But if you’re in one of the California counties where FEMA issued a disaster declaration due to the 2020 wildfires (or if you live elsewhere but depend on enrollment assistance from a friend or family member who lives in one of those counties), you’ve got additional time to make a Part D or Medicare Advantage plan selection for 2021.
If you’re eligible for this extended enrollment opportunity and you complete the plan selection by December 31, your coverage will take effect January 1, just as it would have if you’d completed the enrollment by December 7.

Medicare enrollment in California
Nationwide, 62 million people are covered by Medicare — and more than 10 percent of them are in California. As of October 2020, 6,439,998 California residents had Medicare coverage. But that’s only about 16 percent of the state’s 40 million people, versus about 19 percent of the United States population that is enrolled in Medicare.
For most Americans, Medicare coverage enrollment goes along with turning 65. But Medicare eligibility is also triggered when a person has been receiving disability benefits for 24 months (people with ALS or end-stage renal disease do not have to wait 24 months for their Medicare enrollment). Nationwide, 15 percent of all Medicare beneficiaries are eligible due to disability. It’s a little lower in California, though, with just 12 percent of Medicare beneficiaries enrolled due to a disability.

Medicare beneficiaries can choose to receive their benefits directly from the federal government via Original Medicare or enroll in private Medicare Advantage plans.
Original Medicare includes Medicare Parts A and B. Medicare Part A (also called hospital insurance) helps pay for inpatient stays, like at a hospital, skilled nursing facility, or hospice center. Medicare Part B (also called medical insurance) helps pay for outpatient care like a visit to a doctor (or nurse practitioner or physician assistant) and preventive healthcare service, such as most vaccinations).
Medicare Advantage includes all of the basic coverage of Medicare Parts A and B, and these plans generally include additional benefits — such as integrated Part D prescription drug coverage and extras like dental and vision — for a single monthly premium. But members of Medicare Advantage plans may be required to use a limited provider network for the Medicare plan they select, and total out-of-pocket costs (like deductibles, co-payments, or co-insurance) may be higher than they would be under Original Medicare plus a Medigap plan. There are pros and cons to either option, and no single solution that works for everyone.
Medicare Advantage in California
Although Medicare is funded and run by the federal government, enrollees can choose whether they want to receive their benefits directly from the federal government via Original Medicare or enroll in a Medicare Advantage plan offered by a private insurer, if such plans are available in their area. There are pros and cons to Medicare Advantage and Original Medicare, and no single solution that works for everyone.
Although most counties in the United States do have Medicare Advantage plans available for purchase, there are several counties in northern and central California where Original Medicare is the only option. Of the 58 counties in California, Medicare Advantage plans are available in 43 of them as of 2021. Across those 43 counties, plan availability varies from just two plans in Nevada and Butte counties, to 102 plans in some parts of Los Angeles County.
But 40 percent of Medicare beneficiaries in California were enrolled in Medicare Advantage plans as of 2018, compared with an average of 34 percent nationwide. More than 2.9 million people with Medicare in California, nearly 46 percent of California’s Medicare beneficiaries, had private Medicare Advantage plans as of October 2020 (as opposed to Original Medicare; that figure does not include people who had private Part D or Medigap coverage to supplement Original Medicare). So Medicare Advantage enrollment is growing in California, just as it is nationwide.
Medicare’s annual election period (October 15 to December 7 each year) allows Medicare beneficiaries the opportunity to switch between Medicare Advantage and Original Medicare and/or add or drop a Medicare Part D prescription plan. Medicare Advantage enrollees 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 California
Original Medicare does not limit out-of-pocket costs, so most enrollees maintain some form of supplemental coverage. More than half of Original Medicare beneficiaries receive their supplemental coverage through an employer-sponsored plan or Medicaid. But for those who don’t, Medigap plans (also known as Medicare supplement plans) are designed to pay some or all of the out-of-pocket costs (deductibles and coinsurance) that Medicare beneficiaries would otherwise have to pay themselves.
There are 27 insurers in California that offer Medigap plans. And as of 2018, there were 591,240 California residents with Medigap coverage. Although California has by far the nation’s largest Medicare population, there were four states (Florida, Illinois, Pennsylvania, and Texas) where more people were enrolled in Medigap plans as of 2018. California’s larger-than-average Medicare Advantage enrollment means that fewer people have Original Medicare, and Medigap plans can only be used with Original Medicare.
Medigap plans are sold by private insurers, but 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 C, Plan K, etc.) are the same regardless of which insurer is selling the plan. So plan comparisons are much easier for Medigap policies than for other types of health insurance; consumers can base their decision on premiums (and how premiums change over time) and less tangible factors like customer service, since the benefits themselves are uniform. All Medigap insurers must offer at least Plan A. And if they offer any other plans, they must offer at least Plan C or Plan F to enrollees who were already eligible for Medicare prior to 2020, and at least Plan D or Plan G to enrollees who become eligible for Medicare in 2020 or beyond.
California does not dictate how Medigap insurers can adjust premiums based on age, so most Medigap insurers in the state use attained-age rating, which means that premiums increase as a person gets older. There are a few insurers in California that use issue-age rating instead, with premiums based on the age the person was when they enrolled. Community rating (also known as “no age” rating) means that rates do not vary with age at all, but there are no Medigap insurers in California that use community rating (several states require community rating or issue-age rating, but California is not among them).
Unlike other private Medicare coverage (Medicare Advantage plans and Medicare Part D plans), federal rules do not provide an 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). But California law gives Medigap enrollees a 30-day window each year, following their birthday, when they can switch to any other Medigap plan with equal or lesser benefits, without medical underwriting.
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 more than 700,000 Medicare beneficiaries in California are under 65. Federal rules do not guarantee access to Medigap plans for people who are under 65, but the majority of the states, including California, have stepped in to ensure at least some access to private Medigap plans for disabled enrollees under the age of 65 (federal legislation, including 2018’s H.R.6431, has been considered to expand access to Medigap plans to all Medicare beneficiaries, regardless of age, but the rules have thus far not changed).
For Medicare beneficiaries in California who are under age 65, Article 6 (Section 10192.11) of California’s insurance statute requires Medigap insurers in the state to offer at least plans A, B, D, and G (if offered by the company to any applicants; note that this used to be plans A, B, C, and F, but S.B.784 was enacted in 2019 to swap Plans C and F for Plans D and G, since Plans C and F are no longer available — nationwide — to newly-eligible Medicare beneficiaries as of 2020; the requirement to make plans C and F — if offered by the insurer — available is still applicable for disabled Medicare beneficiaries who became eligible for Medicare prior to 2020). The insurers must also offer either plan K or Plan L, if offered by the company, or Plan M or Plan N, if offered by the company. But none of these provisions apply to Medicare beneficiaries under age 65 who are eligible for Medicare due to having end-stage renal disease (kidney failure).
This is important, because prior to 2021, federal rules also allowed Medicare Advantage plans to reject new applicants with end-stage renal disease, unless the plan was a special needs plan specifically designed for ESRD patients (such plans were not available in most of the state, meaning that ESRD patients had no option to cap their out-of-pocket costs unless they had access to a supplemental employer-sponsored or retiree plan). But this has changed as of the 2021 plan year, under the 21st Century Cures Act. Starting with 2021 coverage, Medicare Advantage plans are guaranteed-issue for all Medicare beneficiaries, including those with ESRD.
California’s statute allows Medigap insurers to charge higher premiums for people under age 65. But coverage must be guaranteed-issue during the six months after a person enrolls in Medicare Part B (regardless of age) or the six months after a person is determined to be retroactively eligible for Medicare Part B. And insurers cannot pay differing broker commissions based on the age of the Medigap enrollee (ie, insurers are not allowed to use lower commissions to dissuade brokers from selling Medigap plans to people under age 65).
Although the Affordable Care Act eliminated pre-existing condition exclusions in most of the private health insurance market, those regulations 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 insurer can look back at your medical history in determining whether to accept your application, and at what premium.
Medicare Part D in California
Original Medicare does not cover outpatient prescription drugs. More than half of Original Medicare beneficiaries have supplemental coverage via an employer-sponsored plan or Medicaid, and these plans often include prescription coverage. But Medicare enrollees without creditable drug coverage need to obtain Medicare Part D prescription coverage. Part D coverage can be purchased as a stand-alone plan, or as part of a Medicare Advantage plan that includes integrated Part D prescription drug coverage.
Insurers in California are offering 32 stand-alone Part D plans for sale in 2021, with premiums that range from about $7 to $130/month.
As of October 2020, there were nearly 5.1 million Medicare beneficiaries in California with Part D prescription coverage. More than 2.3 million had stand-alone Medicare Part D plans, while more than 2.8 million had Medicare Advantage plans with built-in Part D coverage.
Medicare Part D enrollment is available when a beneficiary is first eligible for Medicare, and also during the annual open enrollment period each fall, from October 15 to December 7.
Medicare spending in California
In 2018, Original Medicare’s average per-beneficiary spending in California was $9,868, based on data standardized to eliminate regional differences in payment rates (the data did not include costs for Medicare Advantage).
Nationwide, average per beneficiary Original Medicare spending was $10,096 per enrollee, so Medicare spending in California was about 2 percent below the national average. Per-beneficiary Original Medicare spending was highest in Louisiana, at $11,932, and lowest in Hawaii, at just $6,971.
How does Medicaid provide financial assistance to Medicare beneficiaries in California?
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.
Our guide to financial assistance for Medicare enrollees in California includes overviews of these benefits, including Medicare Savings Programs, long-term care coverage, and eligibility guidelines for assistance.
