If you’re looking to fill in the gaps left by Original Medicare, a Medigap plan might be the answer. Before you sign on the dotted line, however, it’s important to have a thorough understanding of the concept of medical underwriting.

It’s an elaborate and complex process that determines your eligibility, coverage options, and the premiums you pay. But if you plan right, you may even bypass it and make some significant savings on your health insurance costs! 

What is Medicare Supplement?

Medicare Supplement, also known as Medigap, is additional insurance you can buy from private companies to help pay for your share of costs in Original Medicare (Part A and Part B). 

These costs include copayments, coinsurance, and deductibles for services like hospital stays, doctor visits, and medical tests.

There are several standardized Medigap plans available, each labeled with a letter (A, B, C, D, F, G, K, L, M, and N). Each plan offers different benefits, so you need to compare them to find the one that best suits your needs and budget.

Understanding Medigap Underwriting: Why It Matters

Medical underwriting is how insurance companies assess your health status and determine the risk they are taking by insuring you. 

It involves reviewing your medical history to decide whether to offer you coverage, what premium to charge, and whether to impose any waiting periods.

Understanding Medigap underwriting is essential because it can significantly impact your access to Medicare Supplement plans and premiums.

If you have pre-existing health conditions that are too costly, you might be denied coverage, restricted coverage, or face higher premiums if you apply outside guaranteed issue periods.

How Does Medicare Supplement Underwriting Work?

The underwriting process typically involves the following steps:

  1. Application: You complete an application with questions about your health history, medications, and lifestyle. This is often followed by a phone interview. The process can take a couple of days to a month, so you should submit your applications early.
  1. Medical Record Review: The insurance company may request access to your medical records to verify the information on your application.
  1. Decision: Based on your health history and the insurance company’s underwriting guidelines, it will decide whether to offer you coverage, what plans you qualify for, and what premium to charge.

Special Enrollment Periods

There are specific times when you can enroll in a Medicare Supplement plan without undergoing medical underwriting. These are called guaranteed issue periods.

Initial Enrollment Period

The best time to enroll in a Medicare Supplement plan is during the Medicare Supplement Open Enrollment Period. This six-month period begins on the first day of the month a beneficiary turns 65, provided he or she is already enrolled in Medicare Part B. 

During this period, you are guaranteed the right to purchase any Medigap plan available in your state, regardless of your health history.

State Variations

In addition to these federal guaranteed issue periods, some states offer additional open enrollment periods or specific rules for Medigap policies. 

For example, some states allow you to switch Medigap plans during a specific period around your birthday.

For example, Medigap plans can be changed annually in California due to the state’s unique regulation policies. Other states, however, may not offer as much flexibility.

Guaranteed Issue Rights

You may have a guaranteed issue right to buy a Medicare Supplement plan outside the standard enrollment period in certain scenarios. In such situations, insurers must cover pre-existing health conditions and cannot charge you more for them.

You may be eligible for guaranteed issue rights if:

  • After joining Medicare Advantage at 65, you decided to switch back to Original Medicare within a year.
  • Your Medicare Advantage plan shuts down, or you move out of its service area.
  • You lose your employer or union coverage.
  • Your Medigap plan shuts down.
