What Is Medigap? Understanding Medicare Supplement Plans

Original Medicare (Parts A and B) helps cover many health care costs—but not everything.
That’s where Medigap, also called Medicare Supplement Insurance, comes in.

If you’re turning 65 or planning your retirement, understanding how Medigap works can help you avoid unexpected out-of-pocket expenses.


🛡️ What Is Medigap?

Medigap plans are private insurance policies that help pay some of the health care costs that Original Medicare doesn’t cover, such as:

  • Deductibles
  • Copayments
  • Coinsurance

In short, Medigap helps fill the gaps in Original Medicare.

You must have both Part A and Part B to buy a Medigap policy.


📋 What Does Medigap Cover?

Depending on the plan you choose, Medigap may help pay for:

  • Hospital coinsurance and costs
  • Skilled nursing facility coinsurance
  • Part A and B deductibles
  • Part B excess charges
  • Emergency health care when traveling outside the U.S.

👉 Important:
Medigap does not cover prescription drugs, dental, vision, hearing aids, or long-term care.

For prescription drug coverage, you’ll need a separate Medicare Part D plan.


🔹 Common Medigap Plans: Plan G and Plan N

Two of the most popular Medicare Supplement plans are:

  • Plan G: Covers nearly all Medicare-approved costs except for the Part B deductible, which is $257 in 2025.
  • Plan N: Covers almost everything except:
  • The $257 Part B deductible
  • Up to a $20 copay for doctor visits
  • Up to a $50 copay for emergency room visits if not admitted

See the full standardized Medigap plan chart on Medicare.gov


🔹 High Deductible Medigap Option: HDG (High Deductible Plan G)

For those looking for lower monthly premiums, High Deductible Plan G (HDG) is available.

  • In 2025, the annual deductible is $2,870.
  • After meeting the deductible, the plan covers all Medicare-approved costs just like regular Plan G.
  • Important:
    Even though it’s called a “high deductible,” the $2,870 limit is often lower than the maximum out-of-pocket costs seen in many Medicare Advantage plans, which can exceed $5,000 to $8,000 per year.

🛠️ How Do You Enroll in a Medigap Plan?

  • You must have both Medicare Part A and Part B.
  • The best time to enroll is during your Medigap Open Enrollment Period (first 6 months after you turn 65 and enroll in Part B).
  • During this time, you can buy any Medigap plan available in your area without medical underwriting.

🤝 Choosing the Right Medicare Supplement Plan

Medigap plans are standardized, which means a Plan G is the same no matter which company you buy it from.
However, prices can vary, and not every company offers every plan.

I spoke with Linda about auto and home insurance. I appreciated her explanations and follow up communications. After 40 plus years with State Farm, I'm looking forward to the change. Thank you Linda .

Linda is an auto insurance goddess! I have been trying to obtain lower rates for a while and no one has been able to help. Called Linda and within a few minutes she was able to cut my rate in half with all of the same coverages!!
