Navigating the landscape of healthcare coverage after turning 65 can feel overwhelming, and understanding how to bridge the gaps in Original Medicare is often the top priority. AARP Medicare Supplement Insurance, commonly known as Medigap, is specifically designed to help shoulder the cost-sharing that Medicare Parts A and B leave behind, such as copayments, coinsurance, and deductibles. This standardized insurance product is sold by private companies and is guaranteed renewable, meaning your coverage cannot be canceled as long as you pay the premium, regardless of any changes in your health. For many individuals seeking a predictable and straightforward approach to managing healthcare expenses, this option provides a layer of financial security that is difficult to find elsewhere.
Understanding How Medigap Plans Work
These plans work by paying the "gaps" your primary insurance leaves behind. Once you pay your Part A and Part B deductibles, the Medigap policy kicks in to cover the coinsurance or copay amounts. For example, if you are hospitalized and reach the 60-day limit on Medicare coverage, the Medigap plan can cover the additional days in a skilled nursing facility. It is important to note that these supplements do not cover services that Original Medicare does not pay for, such as long-term care, vision or dental care, hearing aids, or private-duty nursing. They strictly exist to minimize the out-of-pocket costs associated with the care that Medicare already approves.
Standardization and Plan Options
One of the most significant advantages of AARP Medigap plans is the standardization of benefits. Each plan type is labeled with a letter—Plan F, Plan G, Plan N, and so on—and every company offering that specific letter must provide the exact same core benefits. While the premiums can vary significantly between providers, the coverage itself is uniform. This structure makes it easier to compare prices without getting confused about differing service levels. Below is a general overview of the most popular standardized options currently available.
F
Covers 100% of Medicare Part A coinsurance and hospital costs.
Covers Part B deductible and 100% of Part B coinsurance.
Covers skilled nursing facility care.
Covers foreign travel emergency.
G
Covers Part A and B coinsurance and hospital costs.
Covers Part B deductible (the main difference from Plan F).

N

Eligibility and Enrollment Periods
Timing is everything when securing the right Medigap coverage, and AARP emphasizes specific windows to ensure you can obtain a policy without facing medical underwriting. The best time to apply is during your Medigap Open Enrollment Period, which begins on the first day of the month you are both 65 or older and enrolled in Medicare Part B. During this six-month window, you have a guaranteed right to buy any Medigap policy sold in your state, regardless of your health status. Missing this window means insurance companies can deny you coverage or charge you more based on pre-existing conditions, making it a critical deadline to remember.
