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.

In this article we’ll discuss:

best medicare supplement plans in California

Finding 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 Medigap Plan G, it will provide you the same exact coverage no matter which company you choose.

That’s right. 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. 

It’s the LAW!

How does California’s Medigap Birthday Rule work?

California Medicare beneficiaries can change their plan each year under a “California birthday rule.” It takes effect 30 days before and ends 60 days after your birthday.

During this time, you will not be denied a Medigap 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 companies or change plan letters with lesser benefits.


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 Plan G to Plan N because Plan N has a lesser benefit.
  • 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.

California medicare supplemental insurance savings is easy

The question remains: How much will you pay for your California Medicare supplement insurance? You’re not getting more benefits by paying more.  

So don’t overpay!

Compare California medicare supplement plans

It is important to know that even though the coverage for California Medicare Supplement Plans are the same, the rates are not. You need to compare the plan letters from company to company. For example, compare Medicare Supplement Plan F from multiple companies.

Medicare Supplement Insurance Plan prices are different when comparing California Medicare Supplement Insurance Companies.

The Medigap lettered plans (Plan F for example) are standardized.  This is a safety net put in place by CMS (Centers for Medicare and Medicaid Services) to protect you. Insurance companies, by law, can’t make any changes to standardized Medigap benefits.

CMS, however, does not regulate premiums. Insurance companies adjust rates based on inflation, overhead, medical pay outs, marketing, etc.

Plan F with ABC insurance company can be very different from XYZ insurance company.

California Plan F premiums 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 Plan F premium is $223.00. 

How Medicare Supplements Work

Think of Medigap plans like this. Premium gasoline (Plan F) is the same at every gas station. However, it has different prices depending on where you buy it. You choose to buy the least expensive premium gas because it’s the same regardless of which station you get it from.

This is how Medigap works.  If you want to purchase Plan F, shop your Plan F with all the companies in your Zip Code.  If you are shopping for Plan G, shop all Plan G plans in your Zip Code.

*Medigap rates listed in example are based on April 2016 premiums.

California Medicare Supplement Benefits

Plan F benefits are the exact same no matter what company you choose.  This applies to all Medigap plan letters.  You do not get better 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 California Medicare Supplement Insurance 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.

Outline Of Coverage

* 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.

California Medigap Locations

Medicare Supplements are available statewide and in the California cities listed below. Understand that your Medigap benefits are based on the Plan letter. Medigap Plan letter benefits are the same no matter where you live.

This is not always the case with Medicare Advantage plans (MAPD). MAPD benefits, copays and deductibles may be different based on your city or location. Please click on this link if you’re looking for additional Medicare Supplement states.

Best decision I made going through REMEDIGAP. I must have watched 40-50 videos from several different carriers and they mostly seemed shady. One I spoke to Joann and walked through options, received some quotes she took care of the rest with absolutely no pressure.
