Find my Medicare path

Start with the eligibility path

How might you qualify for Medicare before 65?

Choose the situation that sounds closest to yours. This educational guide does not determine eligibility; Social Security and Medicare make the official decision.

Typical timing

After 24 months of Social Security disability benefits

Medicare generally begins after you have received Social Security disability benefits for 24 months. Your Medicare card is usually mailed before coverage starts.

Typical timing

The same month Social Security disability benefits begin

People approved for Social Security disability benefits because of ALS do not have the 24-month Medicare waiting period.

Typical timing

A separate dialysis or transplant timeline

Coverage usually starts in the fourth month of dialysis, but it may start earlier with qualifying home-dialysis training or a kidney transplant. ESRD enrollment may require an application.

Use the effective dates on your official Medicare card or notice before enrolling in additional coverage. Review Medicare’s official eligibility paths

Your Medicare coverage choices

Compare the way you receive Medicare.

After Part A and Part B begin, compare provider access, prescriptions, premiums, cost sharing, and travel needs—not benefits alone.

Option 1

Original Medicare + Part D

Use Part A and Part B directly with Medicare and add a standalone Part D drug plan. You can generally see any provider that accepts Medicare. Explore Part D coverage

Option 2

Medicare Advantage

Join a private Medicare-approved plan that provides Part A and Part B coverage. Most include Part D; networks and benefits vary by ZIP code. Explore Medicare Advantage

Option 3

Original Medicare + Medigap + Part D

A Medicare Supplement may help with Original Medicare cost sharing. California availability and premiums before age 65 require a closer look. Understand Medicare Supplements

California Medigap before 65

Some policies are available—but choices and prices can differ.

California lists insurers that offer Medicare Supplement policies to people under 65 who have Medicare because of disability. The available plan letters, eligibility rules, and premiums vary by insurer.

See the California Department of Insurance carrier list

When you turn 65

A new Medigap window can open.

When you are at least 65 and enrolled in Part B, a new six-month federal Medigap Open Enrollment Period begins—even if you already had Medicare before 65. Review the broader choices before that window ends.

Other coverage matters

Confirm who pays first before changing coverage.

Do not cancel employer, Medi-Cal, VA, or other insurance until you understand how it works with Medicare.

Employer plan

Employer size can change the payment order.

For Medicare based on disability, a group plan generally pays first when the employer has 100 or more employees; Medicare generally pays first for a smaller employer. Confirm the exact plan.

Medi-Cal

Medicare generally pays first.

Medi-Cal generally pays last and may help with premiums and cost sharing depending on your eligibility. Keep both cards and follow each program’s rules.

VA coverage

VA and Medicare are separate systems.

VA coverage generally applies in VA facilities. Medicare can cover eligible care outside the VA system, so review the Part B decision carefully.

Family or retiree plan

Get the coordination rules in writing.

Ask the plan administrator whether coverage is based on current employment, which coverage pays first, and what changes after Medicare begins.

Check Medicare’s official who-pays-first guidance

Help with Medicare costs

Check every program you may qualify for.

Income and resource rules differ by program. Apply through an official channel even if you are unsure whether you qualify.

Medicare Savings ProgramsMay help with Part A or Part B premiums and, in some categories, deductibles and cost sharing. Extra HelpMay lower Part D premiums, deductibles, and prescription costs. Medicare + Medi-CalFull-benefit Medi-Cal may provide additional help, and a Dual Eligible Special Needs Plan may be available in your area.

Once you qualify

Keep the next steps simple.

Confirm your Medicare effective dates.Use the dates on your official Medicare card or notice before choosing additional coverage.
Confirm every other source of coverage.Ask who pays first and what would change if you enroll in or leave a plan.
Compare coverage around your actual care.Review doctors, treatments, prescriptions, pharmacies, premiums, and estimated yearly costs.
