Turning 65 while still working in San Ramon puts you at a crossroads that many people aren’t fully prepared for. You may be eligible for Medicare, but if you’re covered under an employer health plan — your own or a spouse’s — you have decisions to make about whether to enroll now or delay without facing late penalties. Understanding how Medicare coordinates with employer coverage, which parts you can postpone, and when enrollment windows open is essential to protecting yourself from unexpected gaps or costs. A licensed Medicare broker serving San Ramon can walk you through your options in plain language, so you can make a confident, well-timed decision that fits your health needs and financial situation.

Video Summary: This video covers how Medicare coordinates with employer coverage when you’re still working past 65 — which parts you can safely delay, how group health plan size changes the rules, and the enrollment window that opens once you eventually leave that job.
Many San Ramon residents wonder if Medicare will let them continue seeing their longtime doctors and specialists. The reassuring answer is yes with a Medicare Supplement (Medigap). It works with nearly any provider that accepts Original Medicare (about 99% nationwide). Your licensed Medicare Wingman at MedicareVideoGuide.com makes it simple to compare plans so you can keep the care team you already know and trust.

Video Summary: This video explains why network access is one of the biggest practical differences between Medigap and Medicare Advantage, especially if you have doctors you don’t want to give up.
Medicare Advantage plans use narrower networks tied to specific hospital systems — KFF’s national analysis found enrollees have access to roughly half the physicians available to someone on Original Medicare in the same area.

Medicare Supplement premiums don’t stay flat, and San Ramon residents often don’t realize how much pricing can vary between carriers for the exact same coverage. Since Plan G and Plan N are standardized by law, price is really the only thing separating one carrier’s policy from another’s. A Medicare agent serving San Ramon can show you a real side-by-side comparison instead of leaving you to guess whether your current premium is competitive.

Video Summary: This video breaks down why Medigap premiums for the exact same plan can rise at very different rates from one carrier to the next, and what that means for shopping around later without medical underwriting getting in the way.

Also asked as: “what happens if I don’t sign up for Part B right away”
Yes, unless you qualify for a Special Enrollment Period due to employer coverage. The Part B late enrollment penalty is generally permanent and is added to your monthly premium for as long as you have Part B.
Also asked as: “does my Medicare plan still work if I relocate”
Original Medicare and Medigap coverage travel with you nationwide. Medicare Advantage and Part D plans are tied to a specific service area, so moving may require switching to a new plan available where you now live.
Also asked as: “does Medicare pay for a yearly checkup”
Yes — Original Medicare covers an annual wellness visit at no additional cost once you’ve had Part B for 12 months. This visit is separate from a routine physical exam and focuses on updating your personalized prevention plan.
Also asked as: “can I stay on my spouse’s employer insurance instead of Medicare”
If your spouse’s coverage comes from a current employer with 20 or more employees, you may be able to delay Medicare enrollment without a penalty, the same way you could with your own employer coverage.
Also asked as: “why do so many people choose Plan G”
Medicare Supplement Plan G is one of the most comprehensive standardized Medigap plans available to people newly eligible for Medicare, covering nearly all out-of-pocket costs under Original Medicare except the annual Part B deductible.
Also asked as: “should I pick Plan G or Plan N”
Medigap Plan G and Plan N are both popular standardized plans, but they split costs differently.
| Plan G | Plan N | |
| Part B deductible | Not covered | Not covered |
| Office/ER copays | None | Small copays apply |
| Part B excess charges | Fully covered | Not covered |
| Monthly premium | Higher | Lower |
Plan G covers nearly all out-of-pocket costs after your Part B deductible, while Plan N has a lower premium in exchange for small copays on some visits and no coverage for Part B excess charges.
CMS sets Medicare Advantage and Part D plan service areas at the county level. Insurance companies decide which counties to offer a plan in based on their own network and cost calculations, which means two people a few miles apart in different counties can have a genuinely different set of plans to choose from — even within the same metro area. Your independent Medicare agent can pull up the specific plans available in your county so you’re comparing your actual options.
Medicare decisions deserve careful planning, whether you’re turning 65, retiring soon, moving to San Ramon, or leaving employer coverage.
