The Best Medicare Supplement (Medigap) Plans in California

Medicare Supplement Insurance is a supplemental insurance plan available to Original Medicare beneficiaries. Even though Original Medicare covers a wide range of preventive and diagnostic services, enrollees still have to pay copays, coinsurance and deductibles.

If you're living on a fixed income, these out-of-pocket costs can be difficult to afford. California Medicare Supplement Insurance, also known as Medigap, covers some of these costs, making health care more affordable. 

Medigap is available to anyone who enrolls in Original Medicare. A third (33%) of California Medicare enrollees have signed up for a California Medigap plan. If you live in California, have Original Medicare coverage and don't have Medicare Supplement Insurance to reduce your out-of-pocket health costs, read on to learn about the Medigap plans available in your state.

What Are the Best California Medicare Supplement Plans?

In California, you may be able to pick from 10 Medicare Supplement Insurance plans. Some plans cover more of your out-of-pocket expenses than others, so it's important to review each one carefully. The chart below explains the benefits included with each plan.

All Medigap plans in California cover your Medicare Part A coinsurance payments and gives you up to 365 days of extra hospital coverage beyond what Medicare Part A normally covers. Each plan also covers Medicare Part B copays, but plans K and L provide less coverage than the other options.

Some of the more robust plans even cover your Medicare Part B deductible, but others don't. Additional limitations may apply; for example, plan K only covers up to 50% of the cost of a blood transfusion. Plans A, B, K and L also provide no coverage for expenses incurred while you're traveling in a foreign country.

Out of the 10 options available, plans F, G and N are the most popular. Many Original Medicare enrollees sign up for plans F and G because of their low premiums, and plan N is popular due to the high level of coverage it provides. In exchange for low premiums on plans F and G, you'll have to pay a high deductible before your Medigap plan kicks in. Plan N has higher premiums, but it also provides more coverage. For example, many of your copays may be covered completely.

How Do I Enroll in Medigap Plans in California?

California Medigap coverage is only available to Original Medicare enrollees. If you enroll in Medicare Advantage, you won't be able to get this type of coverage.

After you sign up for Medicare Part A and Part B, you'll have six months to enroll in Medicare Supplement Insurance. The six-month Medigap open enrollment period begins the month you turn 65. It's important to remember when the Medigap open enrollment period starts because this is the only time you can sign up for Medigap without any restrictions.

During the open enrollment period, Medigap is a "guaranteed issue" type of insurance. That means an insurance company can't deny you due to your age or health status.

If you don't enroll during the six-month Medigap open enrollment period, insurance companies can use a process called underwriting to determine if you qualify for coverage. You may not be able to get supplementary coverage if the insurance company determines that you present too great of a medical risk. Some exceptions apply:

• If you don't purchase Part B coverage when you turn 65 because you still have health coverage through an employer, your California Medigap open enrollment period won't start until the month in which you sign up for Part B. This assumes that your employer-sponsored coverage is ending in the same month.
  
  
• You may have guaranteed issue rights outside the Medigap open enrollment period. If you have guaranteed issue rights, an insurance company must sell you a Medigap plan and can't charge you a higher premium based on your health history and current health status.
  
  
• If you already have a Medigap plan, you may be able to switch to a new Medigap policy without medical underwriting if you enroll within 60 days following your birthday each year. This is called the Medicare Birthday Rule.
