Medigap is a type of supplemental insurance that helps fill the gaps in Original Medicare coverage. It's designed to cover some of the out-of-pocket costs that Medicare doesn't cover, such as copayments, coinsurance, and deductibles.

Medigap plans are standardized, meaning they offer the same benefits regardless of the insurance company selling them. There are 10 different Medigap plans, labeled A through N, each offering varying levels of coverage.

You can purchase a Medigap plan from a private insurance company, but you must have Original Medicare first. This is a requirement, and it's essential to understand that Medigap doesn't cover prescription drugs, which is why you may also need a separate Part D plan.

Medigap insurance is sold by private insurance companies and pays medical costs not covered by Medicare.

Around 20% of Medicare beneficiaries get Medigap, and these policies are designed to help cover all or a portion of extra charges associated with an illness.

You pay monthly Medigap premiums to a private insurance company, in addition to the monthly premium for Medicare Part B.

These premiums can change yearly and rise with age, and you pay them directly to your Medigap coverage provider.

There are 10 standardized Medigap plans, from Plan A to Plan N, with Supplemet plan F only available to those eligible for Medicare before Jan 1, 2020.

History

Medigap insurance has a rich history that's shaped the way it works today. Federal standards were implemented in 1990, including standardized plans and guaranteed plan renewal.

This change brought much-needed consistency to the market. Insurers were required to offer standardized plans, such as Plan A, starting in 2008.

One key restriction was put in place in 2003, when Medigap plans were barred from offering drug coverage to new beneficiaries. This had a significant impact on how plans were structured.

In 2015, the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) prohibited the sale of first-dollar coverage Medigap plans to newly eligible Medicare beneficiaries, which includes plans C and F.

Insurance Works

Medigap insurance is designed to help cover extra charges not covered by Original Medicare, such as copayments, coinsurance, and deductibles.

Around 20% of Medicare beneficiaries get Medigap, according to research from the Kaiser Family Foundation (KFF).

You pay monthly Medigap premiums to a private insurance company licensed to sell policies in your state, in addition to the monthly premium for Medicare Part B.

Monthly premiums can change yearly and rise with age, so it's essential to review your policy regularly.

Medigap policies are standardized, meaning that for each plan, policies from different companies provide comparable coverage, making it easier to shop for the lowest-cost provider.

There are 10 standardized Medigap plans, from Plan A to Plan N, each with its own set of benefits and costs.

Medigap plans sold since 2020 cannot cover the cost of the annual Part B deductible, which is a significant change for those who had plans like C and F before 2020.

You pay monthly premiums directly to your Medigap coverage provider, which do not replace the premiums paid for Medicare Parts B and D.

Medigap policyholders must be enrolled in Medicare Parts A and B to apply for Medigap coverage, and the Medigap open enrollment period is six months from the first month of coverage under Medicare Part B, for those 65 and older.

Part D

Medicare Part D provides prescription drug benefits, which can be a relief for those with ongoing medical needs.

The cost of Part D coverage varies depending on several factors, including the type of plan you choose, the medications you take, and the pharmacy you select.

Most Medigap plans no longer offer prescription drug coverage to new participants, but those who already have it can keep it.

If you have Medigap prescription benefits and switch to a Medicare Part D plan, your Medigap insurer will remove the prescription drug coverage and lower your premium accordingly.

Medicare updates the maximum annual deductible for Medicare D plans each year, and for 2024, it's $545.

The average basic monthly premium for standard Medicare Part D coverage is $55.50 in 2024.

Choosing Healthcare Providers

You can see any doctor in the US that offers Medicare with Medigap insurance.

Medicare Advantage Plans have a network of providers, but you can choose a provider outside the network if you select a Preferred Provider Organization (PPO).

It can cost more to see a provider outside the network with a PPO.

This flexibility can be a big plus, especially if you have a favorite doctor or specialist.

Medigap Requirements

To be eligible for Medigap, you must be at least 65 years old and enrolled in both Part A and Part B of Medicare. You also can't be part of a Medicare Advantage plan.

If you wait until after this period, you may find buying a policy more expensive or impossible due to any history of health issues.

Companies may also choose to sell Medigap policies to Medicare recipients under age 65, but this is not guaranteed.

Cover Preexisting Conditions?

Medigap will cover your costs for preexisting conditions after a six-month waiting period.

If you had six months of continuous creditable coverage before buying Medigap insurance, the plan is required to cover your preexisting conditions right away.

Other circumstances may trigger guaranteed issue rights requiring Medigap providers to offer coverage.

  • Long-term Care
  • Vision Care/Eyeglasses
  • Dental Care
  • Hearing Aids
  • Private Duty Nursing

To qualify for Medigap coverage, you must have Medicare Part A (Hospital Insurance) and B (Medical Insurance), also known as Original Medicare. This is a non-negotiable requirement.

Medicare Advantage Plans and Medigap plans are mutually exclusive. In fact, it's not possible to have both plans at the same time. You must choose one or the other.

You'll need to pay a premium to both Medicare and Medigap separately, as Medicare doesn't cover the costs of a Medigap plan. This means you'll have two separate bills to pay each month.

Medigap plans only cover one person, so if multiple people in your household want Medigap coverage, they'll need to apply individually. This can be a bit of a hassle, but it's worth it for the extra protection.

Here are the key takeaways about Medigap policies:

  • You must have Medicare Part A and B to qualify for Medigap coverage.
  • Medigap and Medicare Advantage Plans are mutually exclusive.
  • Medicare doesn't cover Medigap plan costs, you pay a premium to both separately.
  • Medigap only covers one person, apply individually for household members.
