Yes, creditable coverage applies to Medicare Part B and allows individuals to delay enrollment without incurring late penalties. This generally refers to active employer-sponsored group health insurance (from a company with 20 or more employees) covering the individual or their spouse, ensuring the coverage is at least as good as Medicare.
You generally have two options. You can choose to have both employer insurance and Medicare Part B coverage at the same time. Or, you can choose to delay your enrollment in Medicare Part B and continue with just your employer coverage.
Part B late enrollment penalty
Generally, you won't have to pay a Part B penalty if you qualify for a Special Enrollment Period, or you enroll in a Medicare Savings Program. Learn more about Special Enrollment Periods. You'll pay an extra 10% for each year you could have signed up for Part B, but didn't.
Medicare-eligible veterans with only VA coverage are subject to a late enrollment penalty for Part B. That's because enrollment in the VA health care system is not considered creditable coverage.
As an employee, your FEHB coverage is primary. You can save on paying Part B premiums by deferring enrolling in Part B until your retirement.

No one is automatically exempt from Medicare Part B premiums, but many people avoid paying them by having other creditable coverage (like employer plans when still working), qualifying for Medicare Savings Programs (MSPs) through Medicaid due to low income, or having certain disabilities that qualify them for premium assistance. Those automatically enrolled in Medicare who don't need Part B right away (e.g., due to employer coverage) can delay enrollment without penalty.
You can avoid paying Medicare Part B premiums by delaying enrollment if you have creditable employer coverage (your own or spouse's job with 20+ employees) until that coverage ends (within 8 months to avoid penalties), or by qualifying for a Medicare Savings Program (MSP) to have state/federal funds pay for it due to low income. Other ways to save include using HSA funds, appealing high Income-Related Monthly Adjustment Amounts (IRMAA) for life changes, or enrolling on time during your Initial Enrollment Period.
The only time you need to enroll in Medicare Part B if you have other insurance is if you work for a company with fewer than 20 employees. You can face penalties if you don't enroll during your Initial Enrollment Period. If you have both Medicare and other health insurance, you can have more comprehensive coverage.
