Medicare Supplement: The Basics
This article was updated on: 09/16/2018
What is Medicare Supplement insurance?
Medicare Supplement plans are offered by private insurance companies and can help cover out-of-pocket costs not covered by Original Medicare (Part A and Part B), such as coinsurance, copayments and deductibles. Keep in mind that with Original Medicare there are no out-of-pocket maximums – that is, no limit to what you might have to spend. A Medicare Supplement plan could save you from accumulating big medical bills (that is, many Medicare copayments or coinsurance amounts) if you need extensive medical care. In 47 states, there are up to ten standardized Medicare Supplement plans with lettered names (Plans A, B, C, D, F, G, K, L, M, and N) but not all plans are available in all areas. Minnesota, Wisconsin, and Massachusetts have their own standardized Medicare Supplement plans.
Who can get a Medicare Supplement plan?
To enroll in a Medicare Supplement plan, you must have Medicare Part A and Part B. You generally must also be age 65 or older. While Medicare Part A and Part B might be available to those under 65 with Social Security disability benefits and certain health conditions, the federal government doesn’t require that private insurance companies sell Medicare Supplement policies to people under 65. However, some states do require private insurance companies to sell Medicare Supplement to people under 65.

When can I enroll in a Medicare Supplement plan?
The best time to enroll in a Medicare Supplement policy is during your Medicare Supplement Open Enrollment Period. This is a six-month period that begins on the first day of the month in which you’re both 65 or older and enrolled in Medicare Part B. During this period you can purchase any plan that’s available in your area and private insurance companies can’t refuse to cover you based on a pre-existing health condition. After this period is over you can still apply for Medicare Supplement coverage, but you might be turned down or charged more if you have a health condition.
What does Medicare Supplement not cover?
Medicare Supplement plans typically do not cover:
- Prescription drugs
- Routine dental care
- Routine vision care
- Nursing home care
- Private-duty nursing
What other Medicare plans can I combine Medicare Supplement with?
You can combine Medicare Supplement with
- Original Medicare (Part A and Part B)
- A stand-alone prescription drug plan (Medicare Part D)
You cannot combine Medicare supplement with
- A Medicare Advantage plan
How much do Medicare Supplement plans cost?
Medicare Supplement policies usually charge a monthly premium. The amount of this premium will depend on:
- The plan you choose
- The company you buy the plan from
- The type of pricing the company uses
There are three types of pricing:
- Community-rated (Your age does not affect the price.)
- Issue-age-rated (The premium is based on your age when you sign up for the plan.)
- Attained-age-rated (The premium is based on you current age, and increases over time.)
Be sure to ask about the pricing type as you are shopping for Medicare Supplement plans. You must pay your Part B premium along with your monthly Medicare Supplement premium.
