Medicare Part A Hospital, B Doctor Visits

or my Employer’s Insurance Coverage Group Health Plan?

What about Special Enrollment Periods SEP  when I’m no longer covered by Employer Group Health Coverage?


Medicare & Employer Health Plans?

If you are covered by an Employer Group Health Plan Health Care Advocates Definition, then when you or your spouse turn 65 and become eligible  for Medicare Part A Hospital and Part B Dr. Visits, there are several things to look into, check out and make decisions on:

  • Does your employer’s health insurance plan have more or less than 20 employees?
    • If fewer than 20, you MUST sign up for Medicare A & B as Medicare is Primary which means Medicare pays any bills first and if they don’t pay in full, then other coverage you might have, like your Employers Group health plan would pay.  This may also mean, if you don’t have Medicare, you don’t get your bills paid!  You must enroll in Medicare when you are supposed to, if not, there are penalties!
  • Medicare
  • Don’t just take  our summary.  Medicare’s rules are very complex and confusing.  The rules are not ours, they are Medicare’s, CA State, Insurance Company etc.
  • Follow the links, official brochures and footnotes below for the exact forms and citations you need.  There are penalties if things are done even just a tiny bit wrong.

If your Employer Group Insurance has
#Fewer than 20 employees


If you work for an employer who has fewer than 20 employees, Medicare will be primary and pays before your other coverage.   You MUST  sign up for Part A and Part B *  when you’re first eligible.

If you don’t enroll in Part B  when you’re first eligible, you may have to pay a Part B late enrollment penalty, and you may have a gap in coverage if you decide you want Part B later.  The  Part B General Enrollment Period is quite confusing and unbelievable on how long you might have to wait.

How you delay your Medicare coverage depends on your situation:

  • If you’ll be getting benefits from Social Security or the Railroad Retirement Board (RRB) at least 4 months before you turn 65, you’ll automatically get Part A and Part B. You’ll get your red, white, and blue Medicare card in the mail 3 months before your 65th birthday.
    •  If you don’t want Part B, follow the instructions that came with the card. If you keep the card, you keep Part B and will pay Part B premiums.
  • If you won’t be getting benefits from Social Security or the Railroad Retirement Board (RRB) at least 4 months before you turn 65, you don’t need to do anything when you turn 65.
  • It’s illegal for an employer to offer any incentives to encourage you to take Medicare and drop the employer plan!  Coremarkins *  The Age Discrimination in Employment Act (ADEA) prohibits employers with 20 or more employees from cancelling group health coverage for current employees due to age, even when such employees become eligible for Medicare.  SHRM *

If you would like to do a Zoom meeting, here’s our calendar to set it up.

Make sure that your employers Rx Prescription coverage is credible – that is at least as good as the Standard Part D Rx Prescription  coverage so that you don’t get a Part D Rx  late enrollment penalty.

So, basically, as long as you have great coverage at work, just sign up for Part A Hospital and then get Part B, supplements and Part D Rx when you retireCOBRA, doesn’t count as Employer Group Health Coverage!

Insurance Companies get a fee from the Federal Government, when you enroll in an MAPD plan.  MAPD Plans must cover all A & B services Medicare.Gov *

That's why the premium is very low or ZERO!

Let your Employer know you’re eligible for Medicare A & B


You must tell your employer if you are enrolled, or eligible to enroll, in Medicare (Part A and/or Part B coverage).  Your boss is mandated to tell Medicare who is working there and is eligible for Medicare.

  • I’ve retired early, I’m not 65 yet  What do I do for Health – Medical Insurance?
  • I retired from North Carolina State University july 2018.   They told me that they would supplement my medicare to the same level of medical insurance I had before, but when I asked them how to enroll for that they were less than helpful.   I have social security and they pay a monthly premium  I don’t know whether I am enrolled or what to do to enroll or what exactly I am covered for or what to do.
  • Are Medigap policies written during the 8-month Special Enrollment Period issued subject to the same terms as terms, with regard to pre-existing conditions, as those written during the Initial Enrollment Period?
  • How do I show Medicare that I had qualifying employer coverage?
  • What Happens If I Don’t Take Part B as Soon as I’m Eligible?
    • ***If you do not enroll in Medicare Part B during your initial enrollment period, you must wait for the general enrollment period (January 1- March 31 of each year) to enroll, and Part B coverage will begin the following July 1 of that year. If you wait 12 months or more, after first becoming eligible, your Part B premium will go up 10 percent for each 12 months that you could have had Part B but didn’t take it. You will pay the extra 10 percent for as long as you have Part B.
    • If you didn’t take Part B at age 65 because you were covered under as an active employee (or you were covered under your spouse’s group health insurance plan and he/she was an active employee), you may sign up for Part B (generally without an increased premium) within 8 months from the time you or your spouse stop working or are no longer covered by the group plan. You also can sign up at any time while you are covered by the group plan.
  • This is a wonderful service you’re providing and I will be sure to refer my friends to you for their insurance needs.
    • ***Thank you
  • I’m disabled and covered under my Dad’s retirement plan. I just qualified for Medicare. Must I enroll in Part B or can that be postponed as I have employer coverage?
  • I turned 65 a few months ago, I’m still working and I’ve stayed on my employers group plan.    1. If I cancel my current medical insurance, with my employer, then I guess I would need to sign up for Medicare part “B”, right?   2. My income probably falls into the first tier so there would be a premium of $134 +/-   3. Then I would need a Medicare Supplemental plan like my High Deductible F so another premium of $75 or so, right?    4. Then another supplemental Prescription Plan Part D with a premium of around $40    5. Also, my Granddaughter, whom I have legal custody of is on my group plan, so I would need to get individual coverage for her, right?   6. I believe that was around $350 for a plan I liked.   7. So I would end up with an estimated monthly expense of:   Part B Medicare $134   Plan Hi F Medi Gap $75  Part D Rx $40   Individual Plan for Grand daughter   $350   For a total of $599   8. On Medicare Part “B” how would she pay that premium?  A. Monthly bank withdrawal?

Guaranteed Issue Rights for Medi-Gap

Qualifying #Employer Coverage


Termination of Employment or Retirement Plan

You have the right to purchase a Medi-gap policy for 6 months if your, your spouse’s or a family member’s current employment or retirement plan coverage terminatesor you lose your eligibility due to divorce or death of a spouse or family member. The 6-month period to apply for a Medigap policy starts on the date you receive notice that your health benefits will end. If you do not receive advance notice, the 6-month period starts the date the benefits end or the date of your first denied claim. This protection of California law applies whether your group health benefits were primary or secondary to Medicare.

Our webpage on the pros & cons of Employer Coverage vs Medicare

Loss of COBRA or Cal Cobra

You are also entitled to this protection when you become eligible for COBRA  (Our webpage on COBRA)  or have used up all your COBRA benefits. It does not apply if you stop paying COBRA premiums before you use all your benefits. COBRA benefits are always secondary to Medicare benefits unless you have ESRD and are in a 30-month coordination period. For more information on COBRA, see Medicare & Other Health Insurance.  CA HealthCare Advocates *

COBRA and Medicare are VERY VERY confusing.  Double check with us [email protected]  on your specific situation!!!

4 comments on “Medicare enrollment, if covered by Employer Plan? Retiring?

  1. I misunderstood and did not file for Medicare part B in time when I retired in June.

    Now Kaiser has terminated my health care retirement benefit. I am enrolling now. [In Part B]

    What options do I have or have I lost retirement health care through Kaiser forever?

  2. Can I keep my group plan with over 20 employees and get an MAPD plan. I want the hearing aid benefits.
