Your options
Which kind of plan fits you in San Jose & Silicon Valley?
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.
Santa Clara County typically offers a moderate 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 Stanford take my Advantage plan?
Stanford Health Care accepts Original Medicare and therefore any Medigap policy, and contracts with some Advantage plans and not others, changing yearly. We confirm the plan’s Stanford status in writing before you enroll.
How much does your help cost?
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
