Medicare Supplement Plans, also known as Medigap Plans, are essential for providing additional coverage to Medicare beneficiaries. The challenge for many, however, is comparing the various plans available on the market and finding one that meets their specific requirements. 

Read on to find out the essential criteria for comparing Medicare Supplement plans and identifying the best available coverage options. 

The Need for Supplemental Coverage

Medicare is a federal healthcare program that provides essential health coverage to senior citizens who are 65 years and older, besides those with end-stage renal disease or certain disabilities. 

Medicare is divided into several parts that cover different aspects of healthcare coverage, including Part APart B, Part C and Part D, among others. Beneficiaries might still have to pay deductibles, coinsurance, and copayments in some instances, as defined by the rules. 

These various parts, however, do not, cover all healthcare expenses, leaving gaps that can result in significant out-of-pocket expenses for enrollees. Medicare Supplement Plans close these gaps to offer beneficiaries security and financial safety.

Medicare Supplement Plans are standardized and regulated by the government to cover specific costs that original Medicare doesn’t cover. They are a good choice for those looking for comprehensive coverage. 

Understanding Medicare Supplement Plans (Medigap)

Private insurance policies offered under Medicare Supplement or Medigap plans are intended to work in conjunction with Original Medicare. 

These plans are designed to assist beneficiaries by covering out-of-pocket expenses that are not fully covered by Medicare. They include costs related to emergency medical coverage when traveling outside the US, deductibles, coinsurances or copays, and other out-of-pocket expenses. 

Overview of Standardized Plan Options 

 Each Medigap plan is federally standardized, which means they offer the exact same coverage and benefit options regardless of the insurance company that provides it. 

For instance, Medigap Plan F covers Medicare Part A and Part B deductibles and coinsurance entirely. Medigap Plan G offers a similar level of coverage, with Medicare Part B deductibles being the only exception.

Notes: Y = Yes, — = Not Covered

* Plans F and G also offer a high-deductible plan in some states. With this option, you must pay for Medicare-covered costs (coinsurance, copayments, and deductibles) up to the deductible amount of $2,700 in 2023 before your policy pays anything. (Plans C and F aren’t available to people who were newly eligible for Medicare on or after January 1, 2020.)

** For Plans K and L, after you meet your out-of-pocket yearly limit and your yearly Part B deductible, the Medigap plan pays 100% of covered services for the rest of the calendar year.

*** Plan N pays 100% of the Part B coinsurance, except for a copayment of up to $20 for some office visits and up to a $50 copayment for emergency room visits that don’t result in inpatient admission.

Differentiating Medicare Supplement Plans from Medicare Advantage

Medicare Advantage plans and Medicare Supplement Plans are two separate entities. Medigap plans act as a complement to Original Medicare, helping fill some of its gaps. Medicare Advantage (Part C) plans, on the other hand, offer extra benefits like prescription drug coverage, vision, hearing, and dental care, besides certain other health and wellness services.  

You can choose to enroll in a Medicare Advantage Plan or purchase Medigap when you first start receiving benefits from Medicare, but not both.

Key Factors to Consider When Comparing Medicare Supplement Plans

It is important to examine the specific benefits provided by each offering when comparing Medicare Supplement Plans. Advantages can range from basic protection like Part A coinsurance and hospital expenses to more comprehensive protection such as skilled nursing coinsurance and emergency overseas travel.

Premiums and Cost-Sharing Requirements

Medicare Supplement Plans have monthly premiums. Depending on the level of coverage provided, some plans may have higher premiums than others. You must also understand cost-sharing requirements like deductibles or co-payments related to your plan.

Provider Networks and the Freedom to Choose Doctors and Hospitals

Unlike Medicare Advantage plans, there are no provider networks for Medicare Supplement plans. Beneficiaries are free to choose any healthcare facility that accepts Medicare, so they do not have to be concerned about network limitations when choosing a doctor or a hospital.

Additional Benefits and Added Value 

Even though Medicare Supplement plans provide standardized benefits, some of them might have extra features like foreign travel insurance and wellness program coverage. Those who have specific medical requirements or travel plans will find these additional benefits attractive.

Besides these key factors, you must consider the following points before picking a Medicare Supplement plan:

  1. Household discount: You may qualify for a household discount of up to 12%–15% when you enroll in a Medicare Supplement plan. You’ll need to confirm if you’re eligible for the discount.
  2. Guaranteed issue plan: ‘Guaranteed issue’ refers to an insurance company’s guarantee that it will issue you a policy at the best rate without any underwriting for health or preexisting conditions. It applies only during the Medicare Supplement Open Enrollment period

Steps to Compare Medicare Supplement Plans

Here are the steps necessary for an effective comparison of Medicare Supplement plans:

  1. Assess your healthcare needs and priorities: It is vital to accurately assess your healthcare needs, including prescription drug requirements, anticipated medical services, and financial considerations, before comparing plans. 
  2. Research available plans in your area: Make a list of the Medicare Supplement plans offered in your area based on your research. Use online resources to contract providers directly to get a comprehensive picture of each plan.
  3. Compare plan costs and coverage details: Compare the costs, advantages, and specifics of each plan on your list. Keep a close eye on the cost of the premiums, coverage gaps, and potential out-of-pocket costs.
  4. Consider the stability and reputation of insurance companies: Analyze the reputation and stability of the insurance companies providing the plans. Check out ratings and reviews to learn more about their level of customer service and satisfaction. 
  5. Utilize online resources and tools for plan comparison: Leverage online resources and comparison tools to make your choice. Comparison tools are available on official websites like Medicare.gov, and private insurance websites.
