Should You Get Medicare Part B?

The following information can help you decide if you want to sign up for Medicare Part B. Click on your situation below:



I have Employer or Union Coverage

If you or your spouse (or family member if you’re disabled) is still working and you have health coverage through that employer (including the Federal Employee Health Benefits Program) or union, contact your employer or union benefits administrator to find out how your coverage works with Medicare. It may be to your advantage to delay Part B enrollment.

You can sign up for Part B any time you have current employer health coverage. COBRA and retiree health coverage don’t count as current employer coverage.

Once the employment ends, three things happen:


1. You have 8 months to sign up for Part B without a penalty. This period will run whether or not you choose COBRA. If you choose COBRA, don’t wait until your COBRA ends to enroll in Part B. If you don’t enroll in Part B during the 8 months, you may have to pay a late enrollment penalty. You won’t be able to enroll until the next General Enrollment Period and you will have to wait before your coverage begins. See When Can You Sign Up for Medicare Part A and Part B?

2. You may be able to get COBRA coverage, which continues your health insurance through the employer’s plan (in most cases for only 18 months) and probably at a higher cost to you.
  • If you already have COBRA coverage when you enroll in Medicare, your COBRA will probably end.
  • If you become eligible for COBRA coverage after you’re already enrolled in Medicare, you must be allowed to take the COBRA coverage. It will always be secondary to Medicare.

3. When you sign up for Part B, your Medigap Open Enrollment Period begins. See Medicare Supplement Insurance (Medigap)





I have TRICARE

If you have Part A and TRICARE (insurance for active-duty military or retirees and their families), you must have Part B to keep your TRICARE coverage. However, if ou’re an active-duty service member, or the spouse or dependent child of an active-duty service member, the following applies to you:
  • You don’t have to enroll in Part B to keep your TRICARE coverage while the service member is on active duty.
  • Before the active-duty service member retires, you must enroll in Part B to keep TRICARE without a break in coverage.
  • You can get Part B during a special enrollment period if you have Medicare because you’re 65 or older, or you’re disabled.
  • You don’t need to re-enroll in TRICARE each year. Your coverage will continue as long as you have Part B.

  • Medicare evaluates plans based on a 5-Star rating system. Star Ratings are calculated each year and may change from one year to the next.
  • A Medicare Advantage Private Fee-for-Service plan (PFFS) is not a Medicare supplement plan. Providers who do not contract with the plan are not required to see you except in an emergency.
  • Disclaimer for Institutional Special Needs Plan (SNP): This plan is available to anyone with Medicare who meets the Skilled Nursing Facility (SNF) level of care and resides in a nursing home.
  • Disclaimer for Dual Eligible (Medicare/Medicaid) Special Needs Plan (SNP): This plan is available to anyone who has both Medical Assistance from the State and Medicare.

  • Disclaimer for Chronic Condition Special Needs Plan (SNP): This plan is available to anyone with Medicare who has been diagnosed with the plan specific Chronic Condition.
  • Medicare MSA Plans combine a high deductible Medicare Advantage Plan and a trust or custodial savings account (as defined and/or approved by the IRS). The plan deposits money from Medicare into the account. You can use this money to pay for your health care costs, but only Medicare-covered expenses count toward your deductible. The amount deposited is usually less than your deductible amount, so you generally have to pay out-of-pocket before your coverage begins.
  • Medicare MSA Plans do not cover prescription drugs. If you join a Medicare MSA Plan, you can also join any separate (stand-alone) Medicare Part D prescription drug plan
  • There are additional restrictions to join an MSA plan, and enrollment is generally for a full calendar year unless you meet certain exceptions. Those who disenroll during the calendar year will owe a portion of the account deposit back to the plan. Contact the plan provider for additional information.
  • Medicare beneficiaries may enroll through the CMS Medicare Online Enrollment Center located at www.medicare.gov.
  • Medicare beneficiaries can file a complaint with the Centers for Medicare & Medicaid Services by calling 1-800-MEDICARE 24 hours a day/7 days or using the medicare.gov site. Beneficiaries can appoint a representative by submitting CMS Form-1696.
