Leaving Kaiser in 5 Minutes
Medicare changes how Kaiser works. Here's how to decide whether to stay or go.
Kaiser on Medicare Is Not Employer Kaiser
You have been with Kaiser Permanente for years. Your doctors, hospital, and pharmacy all sit inside one system. That is the point of Kaiser.
At 65, Kaiser offers a Medicare Advantage plan — often called Kaiser Senior Advantage. It is still Kaiser. It is not the same contract you had at work.
Premiums, drug coverage, and the extra benefits all change. Stay only after you have looked at the Medicare version, not the one you remember.
Leaving Means Leaving Those Doctors
Kaiser is a closed system. If you move to Original Medicare plus Medigap, you are not taking your Kaiser physicians with you.
If you stay
- You keep your Kaiser doctors and hospitals.
- Care stays in one system — records, referrals, pharmacy.
- You join Kaiser's Medicare Advantage plan in your county.
If you leave
- Kaiser doctors generally do not take Original Medicare.
- You rebuild your doctor list outside the system.
- Getting back in later is a new enrollment, not a return ticket.
Which Window Lets You Out
At 65, your Initial Enrollment Period is the cleanest time to choose. You can start on Kaiser Advantage, or start on Original Medicare plus Medigap, with no health questions on the Medigap side.
In the first 12 months of your first Medicare Advantage plan, a trial right lets you leave and buy Medigap with no health questions. That is the safety net if you try Kaiser and it is not the right fit.
After that, you can still leave Kaiser every fall. Adding Medigap later usually means health questions. California's Birthday Rule will not help — it only applies if you already have Medigap.
Check the new doctors before you leave. Confirm they take Medicare and are accepting new patients. Then decide.
Stay or Go
If you like Kaiser and your doctors are there, staying is often the right answer. The system is the product.
Leave if you want doctors Kaiser does not have, if you split time outside a Kaiser service area, or if the Medicare plan's costs and drugs do not match what you need.
Neither choice is wrong. The wrong move is assuming the Kaiser you had at work is the Kaiser you get at 65.
Keep Going
Kaiser Advantage is still Advantage. Read that page if the trade is still fuzzy.
