Medicare Supplements for Californian Seniors

Medicare options have changed quite a bit over past few years.

  • First, we had the introduction of high deductible G plans which are now much more common.
  • We lost some of the higher end plans whose only benefit was medication coverage since Part D came on board to cover RX costs.
  • We have also seen the addition of new plans which include more cost sharing but offer lower priced premiums.

Of course, we have to weigh the flexibility of Medicare supplements against the cost savings of Advantage plans.

There's a lot to consider and you're like to received dozens of colorful brochures months before turning 65.

You can quickly run your instant quote for both Medicare and Medicare Advantage plans available in Medicare including the dominant carriers available through our free Medigap quoting engine.

We'll do a quick walk through how Medicare works and the value of Medicare supplements.

We'll then look at which plans have been good values and popular options on the market to address the holes in Medicare.

Let's get started.

First, what is the core Medicare plan?

Medicare is primarily divided into 3 sections that really matter.

  1. There's Part A which deals with hospital or facility based care (the big ticket items in today's world)
  2. Part B for physician charges (think doctor's offices and services)
  3. Part D for medication coverage.

The core benefits for Part A and B work the same way.

Each has a deductible that you need to meet first.

After you meet this deductible, Medicare will then pick up 80% of the charges and you need to pay the other 20%. There is no cap to this 20% which is the key reason to have some type of additional coverage for Medicare.

Part D is handled separately with its own plan which revolves around smaller deductibles and copays with different levels of benefits.

A Medicare eligible person generally does not need to pay for Part A but Part B usually requires a monthly premium depending on a person's income.

Part D will also require a separate premium. Learn all about Part D here.

So that's the core Medicare program in a nutshell.

Where do the Medigap plans come into play?

So what do Medigap plans cover?

Depending on the plan you choose, Medicare supplements will fill in these various holes in Medicare to different degrees.

The key concern is the deductibles, co-insurance of 20%, and of course medication (the separate Part D plan).

The various plans are standardized by Medicare so a G plan is a G plan regardless of the carrier.

This means that we're looking at cost and carrier stability (which ultimately affects costs going forward).

We make it easy to compare the major carriers all on one page with our free and instant California Medicare supplement quote engine.

Speaking of the G plan, this has been the most popular plan for a while for the simple reason that it covers all the major holes of Medicare.

It covers both deductibles (Part A and B), the 20% coinsurance, and it's the only option to cover "excess".

It's hard to justify going down the scale from the G plan since you are making a decision that might reverberate for decades especially, if your health changes. Check our Insider's Guide to Medicare Supplements or How to pick the best Medicare Supplement.

Frequently Asked Questions
▸ What is a Medicare Supplement (Medigap) plan in California?
A Medicare Supplement, or Medigap, plan is private insurance that helps cover costs original Medicare doesn't fully pay-such as copays, coinsurance, and deductibles. Medigap benefits are standardized by the federal government, so a Plan G from one California carrier has the exact same benefits as a Plan G from another; premiums and service are where carriers differ.
▸ Can I see any doctor with a Medicare Supplement plan in California?
Most Medigap plans allow you to see any provider nationwide who accepts Medicare, regardless of which carrier issued your plan. This nationwide flexibility is a key difference from Medicare Advantage, which typically uses a regional network. Compare California Medicare Supplement carriers to see how premiums and service vary.
▸ What is California's Birthday Rule for Medigap plans?
California's Birthday Rule gives Medicare Supplement policyholders a 60-day window around their birthday each year to switch to an equal or lesser-benefit Medigap plan from a different carrier-without medical underwriting. This is a California-specific protection not available in most other states, and it's a valuable tool for managing your premium costs over time.
▸ How much does a Medicare Supplement plan cost in California?
Premiums vary by carrier, plan type, age, and other factors, so there's no single price that applies to all Californians. Because rates change regularly, the best approach is to get a current Medicare quote or speak with a licensed California agent who can compare multiple carriers side by side at no cost to you.
▸ What is the difference between Medicare Supplement and Medicare Advantage in California?
Medicare Supplement (Medigap) works alongside original Medicare and generally lets you use any provider that accepts Medicare, while Medicare Advantage replaces original Medicare and typically uses a network of providers in a specific region. Cost structures, flexibility, and coverage details differ significantly between the two approaches, so comparing both options carefully-ideally with a licensed agent-is recommended before enrolling.
