How to Choose a Medicare Plan in California: A Step-by-Step Guide
Most people turning 65 think choosing Medicare is like picking a health insurance plan at work. It’s not. There are more options, stricter deadlines, and mistakes that can cost you money and stress for years. Here’s how to think through it.
Original Medicare or Medicare Advantage: The First Decision
The first and primary decision you’ll need to make about Medicare is whether you want to go with Original Medicare or choose a Medicare Advantage plan.
Path #1: Original Medicare
With Original Medicare, you create your own plan types.
- Original Medicare (Parts A & B): These parts of Medicare cover your routine hospital and doctor costs at 80%. You can see any Medicare-accepting provider.
- Medicare Supplement (Medigap): These are plans you pay for to help cover the remaining 20% that Original Medicare didn’t cover.
- Part D drug plan: Parts A and B don’t cover your medications, so you’ll buy a Part D drug plan to cover your prescribed medications.
- Dental and vision: Parts A and B also don’t cover glasses or contacts, dental cleanings, fillings, or other dental needs. You can choose to pay out of pocket for these coverages or buy a standalone plan providing coverage.
Many people prefer Original Medicare for the flexibility, but the downsides include more complicated layers of research and purchasing.
Path #2: Medicare Advantage (Part C)
Medicare Advantage takes more of the guesswork out of creating a plan, but also sets limits.
- Bundled: This plan replaces Original Medicare and typically bundles in Part D drug coverage, dental and vision — and sometimes extras like gym memberships. Hundreds of Medicare Advantage plans are available in California.
- Networks: The plans usually operate as HMOs, and so require you to choose a primary care doctor who provides referrals. You can see doctors and specialists within the network.
- Costs: Medicare Advantage (MA) plans can be very low-cost, with $0 premiums, and can limit your out-of-pocket costs for the year.
Many people choose Path #2 for the plan’s simplicity and cost containment, but it’s not a great fit for everyone, particularly if you travel or don’t want any restrictions on who you can see.
Everything below helps you decide which path fits your life.
Ask These Questions Before Choosing Any Medicare Plan
Do you have doctors or specialists you want to keep?
If you have doctors you want to keep today, you need to ensure your plan allows you to see them without the charges that come with seeing an out-of-network doctor.
If your doctor accepts Medicare assignment and you have an Original Medicare plan, that plan should cover your office visits — although you’ll still be responsible for 20% of any charges (unless you have a Medicare Supplement).
Otherwise, make sure your doctor is in-network with the Medicare Advantage plan you choose. Seeing a doctor outside your Medicare Advantage network could lead to expensive medical bills.
Do you travel outside California regularly, or are you a snowbird?
Medicare Advantage plans often require you to see doctors and specialists within the network, typically restricted to a regional area. This means if you spend winters in California and summers in New York, doctors won’t be in-network in both states.
Original Medicare covers any doctor nationwide who accepts a Medicare assignment, but it does not cover international care, even in emergencies.
However, Original Medicare never covers international medical bills, even for emergency visits. A Medigap plan (for an additional premium) can help cover a large percentage of International emergency medical costs, up to a specific amount.
How predictable do you need your costs to be?
If you choose Original Medicare, Medicare supplement plans can help reduce the risk of surprise bills but tend to have higher premiums. The plan’s point is to cover the “gap” between Original Medicare and your wallet.
Medicare Advantage plans typically feature lower, predictable premiums, but come with the risk of big, surprise medical bills if you see a physician out of network. On the other hand, MA plans do have annual out-of-pocket maximums to keep costs down — as long as you stay in-network.
What prescriptions do you take?
Each carrier (and plan) has a unique Part D list of covered drugs, or formulary. These formularies can vary significantly by carrier, so if you take must-have medications or a specialty medication, you’ll need to ensure that the drug is on the list.
Are you healthy now but worried about future costs?
While California offers many consumer-friendly Medicare rights, underwriting rules make it difficult to switch from Medicare Advantage to a Medigap plan.
In most cases, you may have to undergo a health exam and underwriting to get a Medigap plan. Based on the results, the insurer could deny you Medigap coverage or charge you a higher monthly premium.
In a few cases, you may be able to switch without underwriting (for example, if your insurer terminated or changed at least one of their payment amounts).
Medicare Supplement vs. Medicare Advantage: The Core Tradeoff
| Medicare Supplement + Part D | Medicare Advantage | |
|---|---|---|
| Monthly premium | Higher | Often $0 or low |
| Network restrictions | None (any Medicare provider) | Usually, an HMO or a PPO |
| Out-of-pocket exposure | Very low | Has an annual maximum |
| Dental/vision/hearing | Not included | Often included |
| Travel coverage | Nationwide, some international | Regional only |
| Switching later | Medigap requires underwriting | Can switch MA plans annually |
Neither is universally better. The right choice depends on your health, budget, and how you use healthcare.
When To Enroll and When It’s Too Late to Switch Without Penalties
There are several key windows for enrollment:
- Initial Enrollment Period (turning 65)
- Annual Enrollment Period (Oct 15 – Dec 7)
- Medicare Advantage Open Enrollment (Jan 1 – Mar 31)
- Special Enrollment Periods
Your Initial Enrollment Period is the most important window for buying a Medigap plan, which gives you guaranteed issue rights, so you won’t have to undergo a medical exam and/or pay extra for coverage.
If you miss these windows, you may need to pay a Medicare penalty for certain Medicare Parts or undergo tests to qualify for a Medigap plan.
Not Sure Which Medicare Path Is Right for You?
That’s understandable, because choosing between plans is confusing. It’s like walking into a giant, new store and looking for an unusual product specific to a recipe.

Common Mistakes When Choosing
I often see Medicare beneficiaries make similar mistakes before seeking out expert input.
- Choosing a Medicare Advantage plan based on the premium alone without checking if your California doctors are in-network.
- Not reviewing your Medicare Advantage plan during Annual Enrollment and getting surprised by changes, whether in the drug formulary or the plan’s other costs.
- Waiting too long to enroll in a Medicare Advantage Supplement and losing your guaranteed issue rights.
- Assuming a $0 premium plan is “free”.
Why It Matters That I’m Independent
I represent more than a dozen carriers, and I’m not a captive insurance agent to any one company. My service is free because carriers pay the commission, not the client.
I understand the local San Fernando Valley market and the broader Los Angeles area. This includes which Medicare plans have the best networks for which neighborhoods, or the best plans for your medical needs. I also know which Medicare Advantage carriers have been reliable locally for my clients.
