Medicare Supplement Plans: Your Complete Medigap Guide

If you're enrolled in Original Medicare (Parts A and B), you've probably noticed that it doesn't cover everything. Deductibles, coinsurance, and copayments can add up quickly. That's where Medicare Supplement Insurance, commonly called Medigap, comes in. These standardized plans help fill the "gaps" in Original Medicare coverage, giving you more predictable healthcare costs and greater peace of mind.

What Is Medigap and How Does It Work?

Medigap policies are sold by private insurance companies to help pay some of the healthcare costs that Original Medicare doesn't cover. When you have a Medigap policy, Medicare pays its share of the approved amount for covered healthcare services, and then your Medigap policy pays its share.

It's important to understand that Medigap only works with Original Medicare—not with Medicare Advantage plans. You'll pay a monthly premium to the private insurance company for your Medigap policy, in addition to your Medicare Part B premium. In return, you get help with out-of-pocket costs like copayments, coinsurance, and deductibles.

Medigap policies generally don't cover long-term care, vision or dental care, hearing aids, eyeglasses, or private-duty nursing. They also don't include prescription drug coverage, so you'll need to enroll in a separate Medicare Part D plan if you want prescription coverage.

Understanding Standardized Medigap Plan Letters

One of the most helpful aspects of Medigap is that plans are standardized. In most states, including New Jersey, Medigap policies are identified by letters: A, B, C, D, F, G, K, L, M, and N. Each letter represents a different set of standardized benefits, so Plan G from one insurance company offers the same basic benefits as Plan G from another company.

Here's what you should know about the different plans:

Plans F and G are among the most comprehensive options. Plan F covers most out-of-pocket costs, but it's only available to those who became eligible for Medicare before January 1, 2020. Plan G has become the most popular choice for new Medicare beneficiaries, covering everything except the Part B deductible.

Plan N offers solid coverage at typically lower premiums, though you'll pay small copayments for some doctor visits and emergency room visits.

Plans K and L cover a percentage of your costs rather than all of them, which results in lower premiums but more out-of-pocket expenses. These plans do include an annual out-of-pocket limit for added protection.

Plans A, B, D, and M offer varying levels of coverage, with Plan A providing the most basic benefits and the others falling somewhere in the middle of the coverage spectrum.

Plan C is no longer available to those newly eligible for Medicare as of 2020, similar to Plan F.

Monthly Premiums and Guaranteed Issue Rights

Medigap premiums vary based on several factors. Insurance companies may price policies using different methods: some charge the same premium regardless of age (community-rated), others increase premiums as you age (attainment-age-rated), and some base premiums on your age when you first buy the policy (issue-age-rated).

Your best opportunity to buy a Medigap policy is during your Medigap Open Enrollment Period—the six-month period that begins when you're 65 or older and enrolled in Medicare Part B. During this time, you have guaranteed issue rights, meaning insurance companies cannot deny you coverage or charge you more due to pre-existing health conditions.

You may also have guaranteed issue rights in certain special situations, such as when you lose other coverage through no fault of your own, when your Medicare Advantage plan leaves the area or stops providing coverage, or in other specific circumstances defined by federal law.

Choosing the Right Medigap Plan for Your Needs

Selecting the right Medigap plan requires balancing your healthcare needs, budget, and personal preferences. Consider how often you visit doctors, whether you have ongoing health conditions, and how much financial predictability you want.

Some people prefer comprehensive coverage with higher premiums for maximum peace of mind. Others choose plans with lower premiums and are comfortable paying some costs out-of-pocket. There's no single "best" plan—only the best plan for your individual situation.

Remember that while all Plan G policies offer the same basic benefits, premiums can vary significantly between insurance companies. Shopping around and comparing rates from multiple carriers is essential.
