Medicare for Employees

Pay close attention to how many employees the company you work for has so you know whether you need to apply for Medicare or not. If you work for a firm that has less than 20 employees, Medicare will become primary and your group coverage secondary. If your company has over 20 employees, you have the option of deferring and taking your primary group coverage up until you retire. It is important to apply within eight months of no longer working for that employer to be eligible for Medicare. To avoid high premiums, make sure to apply within three months after you turn 65.

Medicare Part A

Medicare Part A covers any services you can receive through a hospital. This would include in-patient care, skilled nursing, and hospice care. If you have paid into social security for a certain number of quarters and are age 65, you can receive Part A with no premium.

Medicare Part B

Medicare Part B covers any out-patient services. This would include X-rays, minor surgeries, routine physicals, and more. Part B premiums are frequently more expensive than Part A and have risen significantly in the last year. These premiums are commonly based on income.

Medicare Part D

Medicare Part D covers prescription drugs. If you use Part D, it is important to reevaluate it each year because they often switch out the prescriptions that are covered.

Advantage Plans

The advantage plan can be considered a one size fits all plan. It is in-network, the least expensive, and in some cases includes vision and dental coverage. If you travel a lot or have certain specialists, another plan may work better for you because it does not cover out of network coverages.

Medigap Options

If you choose the Medicare A,B, and D plan, it is important to have a Medigap policy. There are many Medigap options to choose from that will get you full coverage, the most popular being Medigap G. Without Medigap, there will be a 20% co-insurance gap to fill in, which could be detrimental if there is a medical emergency.

Is it possible to switch from Advantage to Medicare A,B,D, and Medigap?

It is possible to switch from Advantage to Medicare A,B,D, and Medigap. However, you have to be careful because there is a certain time period in which you are eligible for Medigap policies. If you miss that time period, Medigap coverage is not guaranteed. This could cause a 20% co-insurance gap.

Renew Your Plan Annually

If you select the Medicare A,B,D plan, it is important to evaluate Part D because the prescriptions that are covered change annually. This is why you should renew your plan and keep an eye out for changes.
