Choosing the Right Medigap Plan: A Comprehensive Guide

Navigating the complex world of Medicare can be a daunting task, especially when it comes to choosing the right Medigap plan. Medigap, also known as Medicare Supplement Insurance, is designed to cover the gaps in Original Medicare (Part A and Part B) and provide beneficiaries with additional healthcare benefits and financial security. With several Medigap plans available, it’s crucial to understand the options and make an informed decision. In this comprehensive guide, we will walk you through the process of selecting the right Medigap plan to suit your individual needs.

Understanding Medigap

Medigap plans are offered by private insurance companies and work alongside Original Medicare. These plans help cover expenses such as copayments, coinsurance, and deductibles that Medicare does not pay for. It’s important to note that Medigap plans do not cover prescription drugs, so if you require prescription drug coverage, you’ll need to enroll in a separate Medicare Part D plan.

Medigap Plan Options

There are ten standardized Medigap plans available, labeled with the letters A, B, C, D, F, G, K, L, M, and N. Each plan offers a different combination of benefits, and it’s essential to carefully evaluate each option before making a decision. While Medigap Plan F and Plan G have been popular choices in the past, Plan F is no longer available to new Medicare beneficiaries starting in 2020. Let’s take a closer look at some of the key Medigap plans:

  1. Medigap Plan A: This plan provides basic coverage, including Medicare Part A coinsurance and hospital costs up to an additional 365 days after Medicare benefits are exhausted.
  2. Medigap Plan C: Similar to Plan A, Plan C offers coverage for basic benefits but also covers Part B excess charges and skilled nursing facility care coinsurance.
  3. Medigap Plan G: Plan G has gained popularity among Medicare beneficiaries as it offers extensive coverage, including Part A and Part B deductibles, Part B excess charges, and skilled nursing facility care coinsurance.
  4. Medigap Plan N: Plan N is a cost-sharing plan that requires beneficiaries to pay a small copayment for office visits and emergency room visits. It provides coverage for Part A and B coinsurance, but not for the Part B deductible or excess charges.

Evaluating Your Needs

To choose the right Medigap plan, it’s crucial to evaluate your individual healthcare needs and financial situation. Here are some factors to consider:

  1. Health Status: Assess your current health status and anticipate any potential future medical needs. If you have chronic conditions or expect to need frequent medical services, a comprehensive plan like Plan G may be more suitable.
  2. Budget: Consider your monthly budget and how much you can afford in terms of premiums and out-of-pocket expenses. Remember that Medigap plans with more extensive coverage often come with higher premiums.
  3. Travel Plans: If you frequently travel within the United States, consider a Medigap plan that offers coverage for emergency care during your trips. Plans C, D, F, G, M, and N provide coverage for emergency care when traveling outside the country.
  4. Doctor and Hospital Preferences: Ensure that the Medigap plan you choose allows you to visit the doctors, specialists, and hospitals you prefer. Medigap plans do not have network restrictions, so you have the flexibility to choose any healthcare provider that accepts Medicare.

Comparing Costs

Once you have determined your needs, it’s essential to compare costs among different insurance providers offering the same Medigap plan in your area. While the coverage for each plan is standardized, premiums can vary significantly between companies. Here are some cost-related considerations:

  1. Premiums: Compare the monthly premiums charged by different insurance companies for the Medigap plan you are interested in. Keep in mind that premiums can increase over time, so consider long-term affordability.
  2. Rate Structure: Understand how the insurance company calculates premiums, as this can affect future costs. Some insurers use attained-age rating (premiums increase as you age), while others use issue-age rating (premiums are based on your age when you initially enroll) or community-rated (premiums are the same regardless of age).
  3. Discounts and Benefits: Inquire about any discounts or additional benefits offered by the insurance companies. For example, some insurers may offer household discounts or wellness programs that can help you save money in the long run.

Enrollment Periods

To secure the best coverage and avoid potential penalties, it’s crucial to understand the enrollment periods for Medigap plans:

  1. Initial Enrollment Period (IEP): This is a six-month period that begins on the first day of the month in which you turn 65 and are enrolled in Medicare Part B. During this time, you have guaranteed issue rights, meaning insurance companies cannot deny you coverage or charge higher premiums due to pre-existing conditions.
  2. Special Enrollment Period (SEP): In certain situations, you may be eligible for a SEP, which allows you to enroll in a Medigap plan without penalty. Common examples include losing employer coverage, moving out of your plan’s service area, or qualifying for Medicaid.
  3. Annual Open Enrollment Period: Unlike Medicare Advantage plans, Medigap plans do not have an annual open enrollment period. However, you can apply for a Medigap plan at any time throughout the year, but the insurance company may subject you to medical underwriting, which could result in higher premiums or denial of coverage based on pre-existing conditions.


Choosing the right Medigap plan is a critical decision that can significantly impact your healthcare costs and coverage. By evaluating your healthcare needs, comparing plan options and costs, and understanding enrollment periods, you can make an informed choice that provides you with the financial security and peace of mind you deserve. Remember, it’s always a good idea to seek guidance from a Medicare specialist or independent insurance broker who can provide personalized advice based on your unique circumstances.
