Medicare Supplement

What Is a Medicare Supplement?

A Medicare Supplement plan, also called Medigap insurance, is private health insurance designed to help pay the costs that Original Medicare does not fully cover.

Original Medicare generally pays about 80% of approved medical expenses. A Medicare Supplement plan helps cover many of the remaining out-of-pocket costs such as:

Deductibles
Coinsurance
Copayments
Excess charges
Certain emergency foreign travel expenses

These plans work alongside Original Medicare to help reduce unexpected medical bills and provide more predictable healthcare costs.

How Does a Medicare Supplement Work?

When you receive medical care:

Medicare pays its share first
Your Medicare Supplement plan then pays according to the benefits of your specific plan

Because Medicare Supplement plans work with Original Medicare, you can generally see any doctor or hospital in the United States that accepts Medicare patients.

Unlike many Medicare Advantage plans, Medicare Supplements typically do not use provider networks or require referrals to specialists.

What Does a Medicare Supplement Cover?

Coverage depends on the specific Medigap plan you choose.

Some of the most common benefits include:

Medicare Part A hospital deductible coverage
Medicare Part B coinsurance
Skilled nursing facility coinsurance
Blood transfusion coverage
Hospice coinsurance
Foreign travel emergency coverage
Medicare Part B excess charges (certain plans)

Popular plans such as Plan G and Plan N offer strong protection against major medical expenses.

What Medicare Supplement Plans Do NOT Cover

Medicare Supplement plans do not cover:

Prescription drug coverage (Part D)
Routine dental care
Vision care
Hearing aids
Long-term custodial care

Separate plans are usually needed for these services.

Medicare Supplement vs Medicare Advantage

Many people compare Medicare Supplement plans to Medicare Advantage plans.

The biggest differences are usually:

Medicare Supplement	Medicare Advantage
Works with Original Medicare	Replaces Original Medicare administration
No networks in most cases	Often uses HMO or PPO networks
Predictable costs	Pay-as-you-go copays
Higher monthly premium	Lower premiums
Easier nationwide access	Regional provider restrictions may apply

What Are the Most Popular Medicare Supplement Plans?

The two most popular Medigap plans today are:

Medicare Supplement Plan G

Plan G provides very comprehensive coverage and is often considered the gold standard of Medicare Supplements.

Medicare Supplement Plan N

Plan N can offer lower monthly premiums in exchange for small copays and limited exposure to Part B excess charges.

When Can You Enroll in a Medicare Supplement Plan?

The best time to enroll is during your Medicare Supplement Open Enrollment Period.

This is a 6-month window that begins when:

You are age 65 or older
AND enrolled in Medicare Part B

During this time, you generally cannot be denied coverage due to health conditions.

After this enrollment window, medical underwriting may be required in many states.

Are Medicare Supplement Plans Standardized?

Yes.

Medicare Supplement plans are standardized by the federal government. That means a Plan G from one insurance company provides the same basic medical benefits as a Plan G from another company.

However, premiums, customer service, and rate history can vary significantly between carriers.

Is a Medicare Supplement Worth It?

For many retirees, a Medicare Supplement plan offers peace of mind by helping limit unpredictable healthcare costs and providing broad access to doctors and hospitals nationwide.

The right plan depends on:

Your budget
Travel habits
Doctor preferences
Health conditions
Risk tolerance
