Medicare eligibility can be liberating for many struggling with today’s health care costs. However, having an employer health plan can make Medicare decisions complicated. When choosing between Medicare and your employer’s health plan, understand your options and the costs involved.

Do You Have to Apply for Medicare if You Have Employer Health Coverage?

Whether you have to apply for Medicare depends on the size of your employer, the status of your employment, and your Medicare eligibility.

Employer Health Coverage vs. Medicare Eligibility
Company size Medicare considers companies with 20 or fewer employees to be small, and those with over 20 employees are considered large. Small companies may make Medicare mandatory when you become eligible. Large companies cannot establish this requirement since they are the primary payers, while small companies pay secondary to Medicare. Read the Medicare pamphlet Your Guide to Who Pays First for more info.
Employment status For Medicare to consider a health plan creditable coverage, the benefits must be as good as Medicare’s. The covered employee must be currently working, and retirement and COBRA coverages are not considered creditable by Original Medicare regulations. If you do not enroll in Medicare when you first become eligible, and you lack creditable employer health coverage, you may begin to accrue late Medicare enrollment penalties and have enrollment delays.
Medicare eligibility One requirement is the number of quarters you or your spouse have worked. If either of you have worked and paid taxes for 40 quarters or more during your lifetime, Medicare Part A is premium-free, and you should be enrolled when first eligible. Be careful enrolling in any part of Medicare if you or your employer will continue funding a Health Savings Account (HSA) on your behalf, as there may be tax consequences.

Part B has a monthly premium of $170.10 in 2022 and escalates as your yearly income passes predetermined thresholds. If you have creditable employer coverage, you will be eligible for a Special Enrollment Period (SEP) once your group coverage terminates. However, enrollment in Part B may still be advantageous.

What Are My Options if I Keep My Employer Health Coverage?

When becoming eligible for Medicare, compare your coverage choices before enrolling in or deferring Part A and/or Part B. There are several options you can consider:
