How to Choose the Right Medicare Plan in Sunnyvale, CA
-
Assess your health care needs
Consider your current doctors, medications, preferred hospitals, and expected medical procedures for the coming year.
-
Compare plan costs beyond premiums
Look at deductibles, copays, coinsurance, and out-of-pocket maximums. A $0 premium plan may cost more overall if you need frequent care.
-
Check provider networks
Verify that your preferred doctors, specialists, and hospitals are in-network for Medicare Advantage or Medigap plans you're considering.
-
Review prescription drug coverage
Check that your medications are on the plan's formulary and compare costs at your preferred pharmacy.
-
Consider extra benefits
Many Medicare Advantage plans include dental, vision, hearing, fitness, and transportation benefits. Evaluate which extras matter to you.

Common Medicare Mistakes to Avoid
Navigating Medicare can be confusing, and costly mistakes are common. Understanding these pitfalls can save you significant money and ensure you get the coverage you need.
Missing Your Initial Enrollment Period
If you do not sign up for Medicare Part B during your Initial Enrollment Period (the 7-month window around your 65th birthday) and you do not have qualifying employer coverage, you may face a permanent late enrollment penalty of 10% for each full 12-month period you were eligible but did not enroll. This penalty is added to your Part B premium for as long as you have Medicare.
Not Reviewing Plans Annually
Medicare plans change their costs, formularies, and provider networks every year. A plan that was ideal last year may not be the best choice this year. During the Annual Enrollment Period (October 15 – December 7), review your current plan and compare alternatives using the Medicare Plan Finder tool at Medicare.gov.
Assuming Medicare Covers Everything
Original Medicare does not cover dental, vision, hearing aids, or long-term care. Medicare Advantage plans may include some of these benefits, but coverage varies significantly. Without supplemental coverage, you could face substantial out-of-pocket costs for common services seniors need.
Ignoring the Part D Coverage Gap
Medicare Part D has a coverage gap (sometimes called the "donut hole") where you pay a larger share of drug costs after you and your plan have spent a combined amount on covered drugs. While the gap has been significantly reduced in recent years, understanding how your medications interact with this threshold helps you plan financially.
Not Considering Total Costs
A $0 premium Medicare Advantage plan may seem attractive, but total costs include premiums, deductibles, copays, and coinsurance. Calculate your estimated total annual costs based on your expected healthcare usage, not just the monthly premium.
