What Alignment Health Plan is offering in San Francisco for 2027

Alignment is one of 12 carriers offering Medicare Advantage in the county next year; together, those carriers have 46 plans in San Francisco for 2027. The table below lists every Alignment plan by name and type.

What is new, what is leaving, and what has been renamed

Three things changed in Alignment's local lineup between 2026 and 2027:

The 2027 program numbers that apply to every Part D plan

Alignment's plans all include drug coverage, so the Part D rules Medicare sets each year will shape what you pay at the pharmacy. For 2027, CMS has confirmed:

The 2027 Part B premium and deductible, and the 2027 IRMAA income brackets, have not been announced yet. CMS usually releases those in November. We are not estimating them.

How to check an Alignment plan against your doctors and prescriptions

Before December 7, 2026, it is worth running three quick checks on any plan you are considering — new or current:

1. Doctors and hospitals. HMO and HMO-POS plans use networks. Call each provider's billing office and ask whether they are contracted with the specific Alignment plan for 2027. "In network with Alignment" is not enough; plans and networks can differ. 2. Prescriptions. Each plan has its own formulary (drug list) and tier structure. Use the Medicare Plan Finder at medicare.gov — enter your drugs and pharmacy to see how each plan would cover them in 2027. 3. Your situation. The Special Needs Plans in the list have eligibility rules — a D-SNP requires Medicare and Medi-Cal; a C-SNP requires a qualifying chronic condition. You cannot enroll in one unless you qualify.

If you do nothing, your current Alignment plan renews for 2027 as described in the ANOC it mailed you. Nothing lapses automatically.
