UC Davis Health, Sutter, Dignity Mercy and Kaiser, the state’s largest CalPERS retiree population and the VA at Mather — a four-system Medicare market where each plan draws its own line.
What to know before you compare plans in Sacramento County
Sacramento offers a moderate-to-deep Advantage menu built on Sutter, Dignity and (selectively) UC Davis, Kaiser Senior Advantage from three medical centers, every Medigap carrier in California and the full Part D lineup. CalPERS retirees choose from CalPERS’s own Medicare plans instead, which we explain plainly because the two menus get confused constantly.
We compare what is sold at your ZIP code, confirm your doctors and medical group, and set Advantage beside a Medigap policy so the trade-off is plain.

When you can enroll
Turning 65? Your Initial Enrollment Period is the 7 months around your birthday. Already on Medicare? The Annual Election Period is Oct 15–Dec 7, Medicare Advantage Open Enrollment runs Jan 1–Mar 31, and California’s Medigap birthday rule gives you 60 days from your birthday each year to switch supplements without health questions.
Your options
Which kind of plan fits you in Sacramento?
Medicare Advantage
All-in-one Part C plans, often $0 premium, built on a county network — the choice of about half of California, and the one that changed most for 2026.
Medigap pairs with Original Medicare and works with any provider nationwide — UCLA, Stanford, Cedars, City of Hope, or your doctor in Arizona — with California’s birthday rule to switch every year.
Sacramento County typically offers a deep Medicare Advantage menu, every Medigap carrier in California, and the full Part D lineup. Availability is set by county and changes each plan year.
Does UC Davis take my Advantage plan?
Each system contracts with some Medicare Advantage plans and not others, and the lists change every October. With Original Medicare and a Medigap policy there is no network to check, except Kaiser, which is reached only through Kaiser Senior Advantage. We confirm your doctors before you enroll.
I am retiring through CalPERS. Does this site’s advice apply to me?
Partly. CalPERS retirees must enroll in Medicare Part B and choose from CalPERS’s own Medicare plans, which are separate from the individual-market plans we sell. We can still help you understand Medicare itself, Part B timing, IRMAA and how the CalPERS options compare in plain English.
