Employer Size Matters
If the employer has 20 or more employees and coverage is based on active employment, some people may be able to delay Part B.
Medicare Help for People Working Past 65
If you are still working at 65, your Medicare decision may be different. MedigapRx helps you review employer coverage, Part B timing, HSA issues, COBRA, retiree coverage, and what happens when you eventually leave work.

The right decision depends on your employer coverage, company size, HSA status, spouse coverage, and retirement timeline.
Before you enroll, delay, retire, or switch coverage, it is worth reviewing the rules carefully.
Medicare is not always automatic when you keep working. Some people enroll at 65; others may delay certain parts. The details matter.
If the employer has 20 or more employees and coverage is based on active employment, some people may be able to delay Part B.
If the employer has fewer than 20 employees, Medicare may become primary at 65, which can make Medicare enrollment more urgent.
If you contribute to a Health Savings Account, Medicare enrollment can affect whether you can keep making contributions.
If you are covered by active employer group health insurance, you may be able to delay Medicare Part B without a penalty. But that is not true for every kind of coverage.
COBRA, retiree coverage, Marketplace coverage, and small employer coverage may not protect you in the same way as active large-employer coverage. MedigapRx helps you identify which situation you are actually in before you decide.
These are the situations Justin often helps clients sort through before they make a Medicare move.
If the employer has 20 or more employees and you have active group coverage, delaying Part B may be possible.
If the employer has fewer than 20 employees, Medicare may become primary at 65. This should be confirmed before delaying.
If you are covered through a working spouse, the employer size and active-coverage rules still matter.
COBRA is not the same as active employer coverage and may not allow you to delay Medicare safely.
Retiree coverage often expects Medicare to become primary once you are eligible. Plan rules should be reviewed.
Medicare enrollment and HSA contributions do not mix. Retroactive Part A can make timing even more important.
Many people assume they should enroll in premium-free Part A at 65. That may be fine for some people, but it can create HSA issues for others.
Part A is hospital insurance. Many people qualify for premium-free Part A, but enrolling in any part of Medicare can affect HSA eligibility.
Part B is medical insurance. Whether to take Part B at 65 depends heavily on whether Medicare would be primary or secondary.
If you are over 65 and contributing to an HSA, review Medicare timing before enrolling in Medicare or starting Social Security.
If you delayed Part B because you had active employer group coverage, you may be able to use a Special Enrollment Period when that coverage ends.
This is where timing and documentation matter. Some people need Medicare forms such as CMS-40B and CMS-L564 to apply for Part B after employer coverage.
Justin helps connect the Medicare rules to the practical details of your current work coverage and your retirement plans.

Common questions people ask when they are still working at or after age 65.
Not always. The answer depends on active employer group coverage, employer size, HSA status, spouse coverage, and whether Medicare would be primary or secondary.
You may be able to delay Part B if you have qualifying active employer group coverage through your job or your spouse’s job. Confirm before delaying.
Yes. Employer size is one of the biggest factors. Large-employer and small-employer Medicare coordination rules can differ.
No. COBRA is not the same as active employee coverage. If you are Medicare eligible and considering COBRA, review Medicare timing carefully.
Generally, no. Once you are enrolled in Medicare, you generally cannot keep contributing to an HSA. Retroactive Part A can complicate this.
You may qualify for a Special Enrollment Period after active employer group coverage ends. Timing and documentation are important.
Many people use CMS-40B to apply for Part B and CMS-L564 to document employer group coverage after age 65.
