In most states, including California, you cannot count on getting Medigap later
You can buy any Medigap plan with no health questions in the 6 months that start when you are 65 or older and have Part B. After that, a Medigap company in California can ask about your health. It can say no, or it can charge you more. So if you join a Medicare Advantage plan now, you may not be able to get Medigap later. California has a birthday rule, but it only lets people who already have Medigap switch to another Medigap plan. It does not help you get Medigap after you leave Medicare Advantage.
One exception is the trial right. If you joined Medicare Advantage when you first got Medicare at 65, or you left a Medigap plan to try Medicare Advantage for the first time, you can switch back within 12 months. Then you can buy a Medigap plan with no health questions.

A higher drug plan premium is not, by itself, a reason to switch
With Original Medicare, you buy a separate drug plan. In California, 10 drug plans are for sale for 2027, from $5.30 to $252.60 a month. Half of them cost $150.55 a month or less.
- Every 2027 drug plan limits what you pay for covered drugs to $2,400 a year. The drug coverage in Medicare Advantage plans has the same limit.
- The premium is one part of your yearly cost. The calculator above adds premiums, medical costs, and drug costs, so you can see the whole year.
- A Medicare Advantage plan can cost less in a light year. But you also take on its network and prior authorization rules, and you may not be able to get Medigap later.
- If your income is limited, Extra Help can pay most of your drug plan premium and drug costs. Check Extra Help at SSA.gov
