How do I check a Blue Shield of California plan against my doctors and prescriptions before December 7?
Go to medicare.gov/plan-compare, enter your ZIP code, and add your prescriptions and preferred pharmacies. The tool will show each plan's estimated yearly drug cost, whether your drugs are on the formulary, and the tier they sit on. For doctors and hospitals, check the plan's provider directory on the carrier's website — networks can change year to year, so confirm your providers are listed for 2027 specifically, not 2026.
A few steps worth taking before December 7, 2026:
- Make a list of your current doctors, specialists, hospitals and pharmacies.
- Make a list of your prescriptions with dosages.
- Open your ANOC and compare 2026 to 2027 for the plan you are in now.
- Run each plan you are considering through the Plan Finder with that list.
- If something is unclear, call the plan directly or 1-800-MEDICARE (TTY 1-877-486-2048), available 24/7.
