As you approach the age of 65, you become one of the most popular people in the world. You receive mail from every insurance carrier and company overnight, and then the phone calls start. There is genuinely a lot of information that you need to learn and understand. Below we’ll discuss what Medigap coverage is used for.

What is Medigap coverage used for?

Medigap is another name for Medicare Supplement plans. These plans help cover your coinsurance, deductibles, copayments, or any other out-of-pocket costs associated with Original Medicare. They are administered by private insurance companies such as Mutual of Omaha, Aetna, and United American.

The federal government standardizes Medicare Supplement plans. Standardization means that, for the most part, the coverage must be the same regardless of where you are or which carrier you choose.

There are a few states that have exceptions to standardization. Those states include Minnesota, Wisconsin, and Massachusetts.

About Medicare Supplement coverage

As mentioned above, Medigap coverage assists with your Medicare costs. There are 10 Medicare Supplement insurance plans from which to choose. Each program has varying levels of coverage.

Since these plans are supplemental coverage to Medicare, you must continue to pay your Medicare Part B premium in addition to any Medigap insurance you choose.

These plans will cover anything that traditional Medicare covers. Some will even provide you with emergency coverage for foreign travel.

Essentially they’ll cover all benefits and services that Medicare covers. We have listed some of those services below.

  • Inpatient Hospital
  • Skilled Nursing Facility
  • Hospice care
  • Outpatient services and procedures
  • Doctor and specialist appointments
  • Drugs administered in the Hospital, or Doctor’s office

Items that aren’t covered by Medicare supplements include:

Enrollment requirements for a Medigap policy

Medicare beneficiaries can enroll in a Medicare Supplement anytime, as long as they can pass medical underwriting.

A few cases allow you to enroll in a Medigap health insurance plan without underwriting. When you first turn 65, you’ll be in your Open Enrollment Period.

The Open Enrollment Period runs for six months. During this time, beneficiaries can enroll in any Medigap plan without underwriting.

Some states, such as New York and Connecticut, have special rules allowing you to enroll year-round or at certain times without underwriting.

There is also something called Guarantee Issue rights. Seven special situations allow you to enroll in specific Medigap plans without underwriting. Most of these revolve around losing creditable coverage at no fault of your own.

Medicare Supplement plan letter coverages

As mentioned above, they’re ten plan options to choose from. Most Beneficiaries select one of the top three plans. The most popular plans are Plans F, G, and N.

Plan F is the most comprehensive plan available. Essentially you pay your monthly premium, and Plan F pays your Medicare health care costs.

Plan G is the most popular plan when it comes to beneficiaries that are new to Medicare. This health plan offers almost the same coverage as Plan F. The only difference is it doesn’t cover the Medicare Part B deductible.

Plan N is a very popular plan for healthy and cost-conscious individuals. This plan offers an outstanding balance of monthly premiums versus good benefits. The main difference between Plans N and G is that Plan N has copays for doctor visits and the emergency room.

Below is a breakdown of all the available plans and what they cover. Plan F and Plan G both have high-deductible options as well.

What impacts the cost of Medigap Plans

With Medicare Supplement benefits being standardized, you need to consider are few things as you settle on your preferred plan—the monthly premium and the quality of the company.
