Q: What exactly is Medicare?
A: Medicare consists of four parts, each with its own benefits and rules. Here’s a breakdown:
- Medicare Part A provides coverage for inpatient care such as hospital stays, skilled nursing facilities, hospice, home health, and other related services. For most beneficiaries there are no premiums as long as they’ve had 40 quarters of Medicare-covered employment.
- Medicare Part B provides coverage for outpatient care such as doctor visits, lab tests, X-rays, and more. Beneficiaries must choose whether to opt in, but those who delay more than three months past their 65th birthday may face financial penalties. There’s a monthly premium based on the beneficiary’s modified adjusted gross income as reported on their federal tax return two years prior to enrollment.
- Medicare Part C (Medicare Advantage) allows health plans such as Kaiser Permanente to offer plans that cover Medicare Parts A and B and, if available, Part D. Kaiser Permanente Senior Advantage is an example of such a plan. Medicare Advantage plans can offer richer benefits and make the transition to Medicare smoother for plan members and administrators.
- Medicare Part D provides outpatient prescription drug coverage. As with Part B, beneficiaries must choose whether to opt in, but those who delay more than three months past their 65th birthday may face financial penalties.

Q: Does it affect my bottom line if my small business’s Medicare-eligible employees opt to enroll?
A: Yes. Many Medicare Advantage plans are less costly than small group health plans for Medicare-age employees. And if eligible employees enroll in a Medicare Advantage plan such as a Kaiser Permanente Senior Advantage individual plan, they can opt out of your group health plan and decrease your administrative burden.
Q: An employee is covered by both my company’s group health plan and Medicare. Who pays their medical costs?
A: If you have fewer than 20 employees, Medicare is generally the primary coverage and will pay first. If there are still outstanding costs, the group plan would be the secondary source of payment.
There are some exceptions: For instance, if you’ve joined with other employers and/or employee organizations (like unions) to sponsor a group health plan (called a multi-employer plan) and any of the other employers have 20 or more employees, Medicare would generally pay second. However, even in this case your particular plan might ask for an exception, so you’ll need to verify which coverage pays first.
If you have 20 or more employees, your group plan generally pays first if:
- the employee is 65 or older
- you cover any of the same services as Medicare
If your group plan doesn’t pay the entire bill, the doctor or provider can submit the bill to Medicare, which will pay eligible remaining costs up to the Medicare-approved amounts. The member will have to pay the costs of any services that neither Medicare nor the group plan will cover.

Q: Is the Working Aged Risk Contract Option (WARCO) available to my employees over 65? Who’s eligible for WARCO and how does it work?
A: WARCO coverage is available to small businesses with 20 to 50 employees. Even when an employee is 65 or older, the employer continues to pay the under-age-65 rate, while the member may have no cost sharing. Kaiser Permanente moves eligible active members into WARCO when they and their covered spouses decide to enroll in Medicare Parts A and B along with a Medicare Advantage plan like the Kaiser Permanente Senior Advantage group plan.
Q: I offer Kaiser Permanente group coverage to the employees of my small business. When one of my employees with Kaiser Permanente coverage turns 65, are they required to enroll in Medicare? What are their options if they decide to keep working?
A: Medicare-age employees can choose to stay on your group coverage if you have 20 or more employees. Employer group health plans with 20 or more employees are required by law to offer workers and their spouses 65 or older the same health benefits provided to younger employees.
Your employee has several options. If they’re eligible for Medicare at age 65, they can decide to enroll in Part A and pay no premiums provided they have 40 quarters of Medicare-covered employment on record. At that point, the employee can:
- Stay on the group plan and defer enrolling in Part B. They may visit their local Social Security office three months before their 65th birthday and tell Social Security that they don’t want to enroll in Part B until they decide to retire.
- Enroll in Part B and pay the Part B premium in addition to their group premium. The member’s group coverage will be primary and Medicare will be secondary. They’ll have the flexibility to go to any doctor who accepts Medicare in addition to Kaiser Permanente doctors. But the member will have to pay for deductibles and coinsurance required by Medicare, and the claims filed by non–Kaiser Permanente doctors will go through the Medicare Secondary Payer claims process.
- Enroll in Part B, pay the Part B premium in addition to their group premium, then assign their Medicare Parts A and B to Kaiser Permanente and move into WARCO coverage. With this option, your employee will face no cost sharing and can remain part of their group’s experience.
- Enroll in Part B, pay the Part B premium, and opt out of their group plan. With their Medicare Parts A and B coverage, your employee can then enroll in a Kaiser Permanente Senior Advantage individual plan. Download the details of those benefits by county at kp.org .
- Note: Under this option, your employee’s dependents will lose group coverage and will need to be on either COBRA or a separate individual direct pay plan.
Q: One of my employees has a dependent spouse who’s a Kaiser Permanente member and is reaching Medicare age. What are the spouse’s options while my employee is still working?
A: Your employee’s spouse has two options.
- Enroll in Medicare Parts A and B, then opt out of their group coverage and enroll in a Kaiser Permanente Senior Advantage individual plan.
- Stay on the group plan as a dependent, defer enrolling in Part B, and continue to pay the age-band rate.
If you have fewer than 20 employees, then Medicare is the primary payer — otherwise, the group plan will pay first. If the spouse chooses not to enroll in Medicare Parts A and B during the period from three months before up to three months after their 65th birthday, they may face a 10 percent penalty for late enrollment in Part B.
Q: A member is already collecting Social Security benefits and will turn 65 soon. Should they enroll in Medicare?
A: People collecting Social Security benefits before 65 will automatically be enrolled in Medicare Parts A and B at 65. If the member continues to work for a small business with 20 or more employees, the member can return their Medicare card and indicate that they’re deferring enrollment in Part B until they decide to retire. If the member continues to work for a business with fewer than 20 employees, they can keep their enrollment in Medicare Parts A and B for primary coverage. Your costs and administrative burden may be reduced if they enroll in a Medicare Advantage plan such as a Kaiser Permanente Senior Advantage individual plan.
Q: My employees are getting calls from Kaiser Permanente telling them they “have to” enroll in Medicare. Why?
A: We mail valuable information to our members starting at age 64, educating them on Medicare and Kaiser Permanente Senior Advantage. We also call these members to help them transition to Medicare and Kaiser Permanente Senior Advantage. The intention isn’t to force members into Medicare, but to help them understand that they may face significant financial penalties if they delay Medicare enrollment more than three months after their 65th birthday.
