Medicare in Sonoma County is a short menu built around three hospital systems. Choosing well here is less about comparing dozens of plans and more about picking the system you want your care built around.
Proof of concept. The plan and carrier information below is a working prototype — the design, layout, and content will change significantly before this becomes part of the final site.
Here’s what’s actually available this year, from the government’s published plan data — not a sales pitch.

Plan availability, premiums, and star ratings are from the CMS 2026 Medicare plan landscape data (updated 2026-08-06). Beneficiary counts are from the CMS Medicare Monthly Enrollment data (April 2026). Premiums shown may not reflect Part B premiums or low-income subsidies. Medigap benefit descriptions follow the federal standardized plan charts; Medigap premiums vary by age, ZIP code, and carrier and are not shown. Verify details with the plan or Medicare.gov before enrolling.
