2027 Medicare Advantage plans in Sonoma, California

Preview from the CMS 2027 plan list · 13 plans · updated October 02, 2026

Early look at 2027. These are the 2027 plans exactly as CMS first published them (CMS Landscape file cy2027-landscape-202609.zip): premium, out-of-pocket maximum, Part D deductible and plan type. CMS has not published the 2027 Star Ratings yet — the rating column is empty for every plan until it does, which is not a rating of any plan. Copays, dental, vision, hearing, over-the-counter and each plan's drug list fill in as CMS releases those files. Enrollment for 2027 runs October 15 – December 7.

What the star rating means, and what's not shown yet

What the star rating means. CMS rates every Medicare Advantage contract (the "H" number in the plan ID — all plans under it share the rating) on a 1-to-5 scale each October, from about 40 measures of care quality, member experience, complaints and appeals, customer service and, for plans with drug coverage, drug safety and pricing. The 2027 rating is largely based on performance measured in 2025.

5 Excellent4 Above average3 Average2 Below average1 Poor

Not rated means CMS published no overall rating — usually a contract too new to be measured or with too few members ("not enough data"); it is not a low score. A 5-star contract can be joined outside the normal enrollment windows (the 5-star Special Enrollment Period, Dec 8 – Nov 30). Medicare.gov flags contracts rated below 3 stars for three years running as low-performing. Stars describe the contract's past performance as CMS measured it; they are not a recommendation, and they do not tell you whether a plan's network, drugs or costs fit you.

Premiums and the out-of-pocket maximum are Part A/Part B plan costs as filed; the Part D deductible is the plan's drug deductible. Copays for doctor visits, dental, vision, hearing, over-the-counter and other extra benefits, and each plan's drug list, are not in the 2027 plan list yet — CMS publishes them in late October and this page will show them then.
