Do I need Part B if I have insurance through my employer?

What question should I ask human resources?

Ask how many employees the employer has. If the employer has 20 or more employees, the group plan generally pays first and Medicare pays second. If it has fewer than 20, Medicare generally pays first, and the plan may pay little or nothing for services Part B would have covered if you are not enrolled (Medicare.gov, Who pays first). At a small employer, delaying Part B can leave large gaps even though the Special Enrollment Period still protects you from the penalty.

Ask whether the plan is a group health plan based on current employment, whether it is a large-group plan if you have a disability, and whether claims will be denied or reduced if you are Medicare-eligible but not enrolled in Part B. Medicare.gov's working past 65 page tells you to ask the employer that provides the insurance. Get the answer in writing.

When is the answer usually to enroll in Part B now?

Retiree coverage, COBRA, Marketplace coverage, and many small or individual policies are not reasons to delay. Medicare.gov says if you have insurance that is not from a job, rules vary and some private coverage pays less, or does not pay, once you are eligible for Medicare. If you are already retired and on COBRA, sign up for Medicare when you first qualify rather than waiting for COBRA to end.

How does this interact with Part D and Medigap?

Creditable employer drug coverage can delay Part D without a penalty if you do not have a 63-day gap. Keep the annual creditable-coverage notice. Medigap federal Open Enrollment is tied to Part B enrollment at 65 or older, and it is not part of Medicare Annual Enrollment. If you delay Part B for years, you also delay that Medigap window. See Advantage versus Supplement.

What happens to dependents if I enroll in Medicare?

Your Medicare decision can change who remains on the employer plan. Some employers drop the employee from the group plan once Medicare is primary, which can affect a younger spouse. Ask whether dependents can stay and what they pay. That answer belongs in the same written request as the Part B question.

If a spouse will need Marketplace coverage after leaving the group plan, that spouse may have a Special Enrollment Period. See coverage outside Open Enrollment. Do not leave that person uninsured while you complete Medicare paperwork.

Common questions

If my employer plan is expensive, should I drop it and take only Part B?

That is a comparison of two coverage paths, not a default. Confirm networks, drugs, and whether delaying or dropping group coverage affects dependents. There is no single answer for every workplace plan.

Does a Marketplace plan let me delay Part B?

Medicare.gov treats Marketplace coverage as insurance that is not from a job. It is not the current-employment Special Enrollment Period described for group health plans.

Does the size of my employer matter for Part B?

Yes. If your employer has fewer than 20 employees, Medicare generally pays first and the employer plan pays second, so going without Part B can leave you with large bills. With 20 or more employees, the group plan generally pays first.
