California Medicare Supplement Plans
If you’re trying to find the best California Medicare Supplement plans, you’ve come to the right place. In this guide, we’ll walk you through how to compare plans and find the best value when shopping for California Medigap plans.

Best Medigap plans in California

Shopping for the best plan starts with understanding how plans work. We mentioned that Medicare Supplements are standardized plans, but what does that actually mean?

When you purchase a particular Medicare Supplement Plan, like Plan G, it will provide you the same exact coverage no matter which company you choose.
Your Medicare coverage is the same no matter the company. It’s the same if it’s Blue Cross Blue Shield, Mutual of Omaha, Cigna or any other Medigap company. 
That’s right. It’s the LAW!

How Does California’s Medigap Birthday Rule Work?

California’s Medigap birthday rule is a state law that allows you to change your Medigap plan during your birthday month. This means that if you’re not happy with your current plan, you can switch to a new one. The birthday rule applies to all plans.

California Medicare beneficiaries can change their plan each year. It takes effect 30 days before and ends 60 days after your birthday. During this time, you will not be denied a plan due to health risks. You must be currently enrolled in a California Medigap plan if you want use your birthday rule. You will be able to keep your same plan letter, but change insurers or change plan letters with lesser benefits.
The birthday rule allows residents who are eligible for Medicare to enroll in a Medigap plan during their initial enrollment period, which begins on the first day of the month that they turn 65 years old. Residents can also enroll in a Medigap plan during the open enrollment period, which begins on October 15th each year.


California Birthday Rule Example

Let’s say you have a Plan G from “Company XYZ”.
  • You can move from Company XYZ to Company ABC’S Plan G if they have a lower premium.
  • You could also change from Medigap Plan G to Plan N. That’s because Medicare Supplement Plan N has a lesser benefit compared to G.
  • However, you couldn’t switch from Plan G to Plan F because that’s an INCREASE in benefits.
 Your plan’s effective date will be after your birthday. The new premium for your plan will reflect your new age.
The birthday rule gives California beneficiaries an excellent opportunity to shop their plans annually. Even if you have health conditions that may prevent you from qualifying from “traditional underwriting.” California’s Medigap Birthday Rule provides you a guaranteed issue opportunity each year on your birthday to save money.

How much does a Medicare Supplement plan in California cost?

How much will you pay for your California Medicare supplement insurance? It will depend on a variety of factors such as where you live, your age, gender and if you use tobacco. The monthly premium of your plan is usually lower the younger you are. 

During your Medigap open enrollment period, you can choose any plan available to you. Shopping Medicare plans is key to saving money. Remember, you’re not getting more benefits by paying more.  

So don’t overpay!

Compare Medicare Supplement Insurance Plans

It is important to know that even though the coverage for these plans are the same, the rates are not. You need to compare the same plan letters from company to company. For example, compare Plan F from multiple insurers.
Medicare Supplement Insurance Plan prices are different when comparing private insurance companies.
The Medigap lettered plans are standardized. This is a safety net put in place by CMS (Centers for Medicare and Medicaid Services) to protect you. Insurers, by law, can’t make any changes to standardized Medigap benefits.
CMS, however, does not regulate premiums. Insurance carriers adjust rates based on inflation, overhead, medical pay outs, marketing, etc.
Plans with ABC insurance company can be very different from XYZ insurance company.
California premiums can have a difference of $75 from the lowest to the highest priced plan.
*Example: Male, age 65 in zip code 92551:
  • The lowest Plan F premium is $148.00.
  • The most expensive is $223.00. 

How Medigap in California Works

Think of these Medigap policies like buying a Snickers bar. The candy bar is the same at every convenient store. However, it has different prices depending on where you buy it. You choose to buy the least expensive Snickers bar because it’s the same regardless of which store you get it from.
This is how shopping for Medigap works. If you want to buy Plan M, shop your Plan M with all the companies in your Zip Code. If you are shopping for a different plan letter, shop that plan letter and compare rates.

California Medicare Supplement Benefits

Plan letter benefits are the exact same no matter what company you choose. This applies to all plan letters. You do not get more benefits by selecting a big or small Medigap insurance company.
Price comparison shopping is important. You must make sure that you are not spending more than you have to. Plans with the same letter have the exact same coverage.
Here is a Plan letter comparison. Please take a moment and compare benefits. You may also want to read the  Medigap Plan F or Plan G comparison article. It may help you understand their differences.

Original Medicare Coverage with Medigap

Original Medicare is made up of two parts called Medicare Part A and Part B. Your hospital insurance is with Part A and Medicare Part B covers your medical insurance. Original Medicare covers you for approximately 80% of your Part B doctor visits. That’s why people enroll in Medicare Supplement. These plans help fill in the gaps of Original Medicare.

* Plans F and G also offer a high-deductible plan in some states. With this option, you must pay for Medicare-covered costs (coinsurance, copayments, and deductibles) up to the deductible amount of $2,340 in 2020 ($2,370 in 2021) before your policy pays anything. (Plans C and F aren’t available to people who were newly eligible for Medicare on or after January 1, 2020.)

** For Plans K and L, after you meet your out-of-pocket yearly limit and your yearly Part B deductible, the Medigap plan pays 100% of covered services for the rest of the calendar year.

*** Plan N pays 100% of the Part B coinsurance, except for a copayment of up to $20 for some office visits and up to a $50 copayment for emergency room visits that don’t result in inpatient admission.
