If you’re a Medicare beneficiary in Washington, D.C., you may want to consider signing up for a Medicare Supplement (or Medigap) plan. Medigap plans in Washington, D.C., may help cover health-care costs associated with Original Medicare, Part A and Part B, such as copayments, coinsurance, deductibles, and other out-pocket expenses. Since there may be a variety of Medigap plans available in your area, it may be a good idea to familiarize yourself with what each plan covers, and get help selecting one that works for your health and budget needs.

How Medicare Supplement plans work in Washington, D.C.

There are 10 standardized Medigap plans in D.C. (and in most states), and they’re identified by one of 10 letters (A, B, C, D, F, G, K, L, M, and N). All plans of the same letter offer the same benefits, and the same 10 plans are generally available in 47 states, plus Washington, D.C.. Three states – Massachusetts, Minnesota, and Wisconsin – offer different Medigap plans. Also note that some companies may offer additional innovative benefits.

In order to join a Medicare Supplement (Medigap) plan in Washington, D.C., you must already be enrolled in Original Medicare, Part A and Part B. You may want to sign up for a Medigap plan during your Medigap Open Enrollment Period, which starts the first day you are both age 65 or older and enrolled in Medicare Part B. This enrollment period lasts for six months. During this time frame, you can sign up for any Medicare Supplement plan available in your area, with the insurance company of your choosing, and not be subject to medical underwriting or any restrictions for pre-existing conditions (although waiting periods may apply). This means that an insurance company can neither deny nor charge you more for a Medigap plan in Washington, D.C.. If you decide to apply for a Medigap policy outside of this time, you may be denied coverage or charged more for the insurance policy.

It’s very important for you to know that even if you sign up for a Medicare Supplement plan, you must remain enrolled in Original Medicare, Part A and Part B, and go on paying your Medicare Part B premium, in order to keep your health insurance coverage. Since Medigap plans are meant to supplement and not replace Original Medicare, failure to pay your Medicare Part B premium may result in your being disenrolled from Medicare and losing your health coverage.

Also be aware that Medigap plans currently sold in Washington, D.C., do not offer prescription drug coverage. The same is true in all states, so you may want to enroll in a stand-alone Medicare Part D Prescription Drug Plan if you want to receive coverage for drug expenses. Medicare Part D Prescription Drug Plans in Washington, D.C., and the rest of the United States are available through private, Medicare-approved insurance companies.

  • Once you reach the out-of-pocket limits indicated in the table above, Medicare Supplement plans K and L pay 100% of covered services for the calendar year.

Choosing a suitable Medicare Supplement plan in Washington, D.C.

As stated earlier, Medicare Supplement plans in Washington, D.C., with the same letter designation don’t vary in coverage or benefits. However, each independent insurance company offering Medicare Supplement plans can determine its own monthly premium structure. This means that if you live in Georgetown, in Ward 2, you may pay more or less than a resident of Capitol Hill, in Ward 6, for an identical Medicare Supplement plan. It may be a good idea to compare all Medicare Supplement plans available in your area, and then choose a Medigap plan in Washington, D.C., based on your personal health and budget needs.
