Turning 65 in California: Medicare Supplement Enrollment Checklist (2026)

---

If you are turning 65 soon, this is the most important time to review your Medicare Supplement (Medigap) options.

During your initial enrollment window, you can choose a Medicare Supplement plan without answering health questions, making this the easiest time to select coverage that fits your long-term needs.

I help Medicare beneficiaries throughout California and Nevada compare Medicare Supplement plans and understand their enrollment choices before coverage begins.

When Should You Start Reviewing Medicare Supplement Options?

Most people should begin reviewing their options about three months before turning 65.

Starting early allows time to:

• Understand how Medicare Parts A and B work
• Compare Medicare Supplement plans
• Review insurance company options
• Coordinate your coverage start date

Planning ahead helps avoid last-minute decisions and ensures your coverage begins smoothly.

What If You Continue Working After Age 65?

If you are still working at age 65 and covered under an employer group health plan, you may be able to delay enrolling in Medicare Part B without penalty.

Many people choose to enroll in a Medicare Supplement plan later when their employer coverage ends.

However, the timing rules depend on:

• The size of your employer
• Whether your coverage is based on active employment
• When your group coverage ends

When employer coverage ends, you typically receive a Special Enrollment Period to enroll in Medicare Part B and apply for a Medicare Supplement plan.

I’m happy to help review your situation and explain the best time to enroll based on your coverage.

Is There a Penalty If You Delay Medicare Part B?

Some people who delay enrolling in Medicare Part B after age 65 may have to pay a late-enrollment penalty.

However, many individuals who continue working and remain covered under an active employer group health plan can delay Part B without penalty.

The penalty usually applies if someone delays Part B after age 65 without qualifying employer coverage.

In many cases, the penalty increases your Part B premium for as long as you have Medicare Part B.

Because enrollment timing depends on your individual situation, it’s helpful to review your coverage before deciding when to start Medicare.

What Is Your Medicare Supplement Open Enrollment Period?

For most people, the Medicare Supplement Open Enrollment Period begins when you are age 65 or older AND you are enrolled in Medicare Part B

This enrollment window lasts six months.

During this time:

• You cannot be denied coverage
• No health questions are required
• All available Medicare Supplement plans are open to you

This is the most flexible enrollment opportunity you will have.

What If You Qualified for Medicare Before Age 65 Due to Disability?

Some individuals become eligible for Medicare before age 65 due to disability.

In California, these beneficiaries may enroll in certain Medicare Supplement plans before age 65 and then receive another Medicare Supplement Open Enrollment Period at age 65, creating a second opportunity to review coverage and compare plans.

If this applies to you, I’m happy to help explain your available options.

Why Many People Choose a Medicare Supplement Plan at Age 65

Medicare Supplement plans help cover expenses that Original Medicare (Part A and Part B) does not pay, including:

• Deductibles
• Copayments
• Coinsurance amounts

Because Medicare Supplement benefits are standardized, the benefits of each plan letter are the same regardless of which insurance company you choose.

Many people select Plan G because it provides the best coverage today with predictable long-term costs.

How to Choose the Right Medicare Supplement Company

Since coverage benefits are standardized, selecting a company usually involves comparing:

• Monthly premium
• Long-term rate stability
• Company experience
• Customer service reputation

I help clients compare multiple companies so they can make an informed decision before coverage begins.

What Happens If You Apply After Your Enrollment Period Ends?

If you apply after your Medicare Supplement Open Enrollment Period ends, you will be required to answer health questions and go through medical underwriting, which could affect your eligibility for coverage.

That’s why reviewing your options before your enrollment window begins is so important.
