Medicare, Explained by Someone Who'll Actually Pick Up the Phone

Original Medicare covers a lot — but it doesn't cover everything. Copayments, deductibles, and coinsurance can add up fast, and sorting through your supplement options shouldn't mean sitting on hold with a national hotline. At Nauertz Insurance Agency, our licensed local agents help Inland Empire residents compare Medicare supplement insurance plans in plain language, without the pressure.

What Medicare Supplement Insurance Actually Covers

Original Medicare (Parts A and B) leaves meaningful gaps in coverage. A Medicare supplement plan — also called Medigap — is designed specifically to fill those gaps. Depending on the plan you choose, it can help cover costs that Original Medicare does not fully pay, including Part A coinsurance and extended hospital stays, Part B coinsurance or copayments at the doctor's office, the first three pints of blood, hospice care coinsurance under Part A, skilled nursing facility coinsurance, and in some plans, both the Part A and Part B deductibles. Certain plans also include a benefit for foreign travel emergency care, up to plan limits.

 

Medigap plans are sold by private insurers but standardized by the federal government, which means Plan G from one carrier covers the same core benefits as Plan G from another. What differs between carriers is the premium — and that is where comparing your options with a local agent can make a real difference.

Medicare Supplement vs. Medicare Advantage: What's the Difference?

These two types of coverage are frequently confused, and the distinction matters. Medicare Supplement (Medigap) works alongside Original Medicare. You keep your Medicare benefits, and your supplement plan steps in to cover what Medicare leaves behind. You can see any doctor who accepts Medicare — no network restrictions, no referrals required.

 

Medicare Advantage (Part C) replaces Original Medicare with a plan run by a private insurer. These plans often include additional benefits like dental and vision, but they typically come with provider networks, prior authorization requirements, and cost structures that can be harder to predict.

 

Neither option is universally better. The right choice depends on your health situation, your preferred doctors, how much you travel, and your budget. We help you think through those factors clearly — not push you toward whatever pays the highest commission.

Enrollment Timing: When You Can Sign Up and What to Know

Getting your enrollment timing right is one of the most important decisions in the Medicare process. The best window to enroll in a Medicare supplement plan is your Medigap Open Enrollment Period — a six-month window that begins the month you turn 65 and are enrolled in Medicare Part B. During this window, insurers cannot deny you coverage or charge you more based on your health history.

 

Outside of that window, insurers in most states can apply medical underwriting, which means your health history may affect your eligibility or your premium. There are exceptions — qualifying life events and special enrollment situations do exist — but the rules are specific and easy to misread.

 

The Annual Enrollment Period (October 15 through December 7 each year) is primarily for Medicare Advantage and Part D prescription drug plan changes, not Medigap. Knowing the difference between these windows keeps you from missing a critical opportunity. We walk every client through the timeline before any decisions are made.

Why Local Guidance Matters More Than a 1-800 Number

National Medicare lead-generation sites and call centers are built to move volume. You fill out a form, your information gets routed to whoever paid for the lead, and someone who has never met you starts reading from a script. That model works fine for the person selling — not always for the person buying.

 

We have been serving the Inland Empire from our Upland office for more than 33 years, and our agency has been family-owned since 1931. When you call us, you reach a licensed local agent — not a queue. We remember your situation from one conversation to the next, and we are still here when your needs change, when you have questions at renewal time, or when a claim raises something you don't understand. That kind of continuity is hard to find in a category that has been largely taken over by aggregators and automated phone trees.

Common FAQs

Medicare Supplement Insurance: Common Questions

  • What is the difference between Medicare supplement insurance and Medigap?

    There is no difference — Medigap is simply the common name for Medicare supplement insurance. Both terms refer to the same type of private health insurance policy designed to cover the out-of-pocket costs that Original Medicare does not pay.

  • Which Medigap plan is best for most people in California?

    Plan G is currently the most comprehensive Medigap plan available to new Medicare enrollees in California and is one of the most widely chosen. It covers nearly all out-of-pocket costs under Original Medicare, with the exception of the Part B deductible. That said, the right plan depends on your health, your budget, and how you use healthcare — which is why a one-on-one comparison with a licensed agent is worth the time.

  • Can I be denied a Medicare supplement plan because of a health condition?

    During your Medigap Open Enrollment Period — the six months starting when you turn 65 and enroll in Part B — insurers cannot deny you coverage or charge higher premiums based on your health. Outside of that window, medical underwriting may apply in most states, including California. There are some guaranteed-issue situations that provide exceptions, and we can help you determine whether any apply to your circumstances.

  • Does Medicare supplement insurance cover prescription drugs?

    No. Medigap plans do not include prescription drug coverage. If you want coverage for medications, you would need to enroll in a separate Medicare Part D prescription drug plan. We can help you understand how Part D fits alongside your supplement coverage.

  • How much does Medicare supplement insurance cost in the Inland Empire?

    Premiums vary based on the plan type, the carrier, your age, and in some cases your location. In the Inland Empire, Plan G premiums for a 65-year-old can range considerably from one carrier to the next — which is one reason it pays to compare. As an independent agency, we work with multiple carriers and can show you options across the market rather than a single company's lineup.
