What it is

Medigap Plan G is one of the standardized Medicare Supplement plans sold by private insurance companies. It works alongside Original Medicare (Part A and Part B). It is not a stand-alone health plan, and it is not Medicare Advantage.

In general, Plan G helps cover many cost-sharing amounts that Original Medicare does not, such as hospital coinsurance and certain Part B charges. It generally does not include the Part B deductible, which you would typically pay yourself. A high-deductible version of Plan G also exists, with a different cost structure.

Plan G benefits are standardized by letter, so the core coverage is the same from one carrier to the next in most states. Massachusetts, Minnesota and Wisconsin standardize Medigap differently. Plans A, B, D, G, K, L, M and N are sold to people newly eligible for Medicare. Plans C and F are available only to people who became eligible before January 1, 2020. Plans E, H, I and J were discontinued and are not sold today.

How it’s traditionally been approached

People have traditionally chosen Medigap alongside Original Medicare because they want to see any provider nationwide that accepts Medicare, without networks or referrals. Many also value predictable cost-sharing from year to year.

Others have chosen Medicare Advantage instead. Those plans often have lower monthly premiums, an annual out-of-pocket maximum, extra benefits and, in many cases, drug coverage. They may also use provider networks, prior authorization and copays. Both paths are reasonable, and the better fit depends on the person.

Medigap trade-offs are worth knowing. Premiums are generally higher than many Medicare Advantage premiums. Outside open enrollment or guaranteed issue periods, medical underwriting may apply. Medigap does not include drug coverage, so a separate Part D plan is needed, and it does not include routine dental, vision or hearing.

How the right licensed agent may help

A Medigap agent may help you understand how Plan G compares with Plan N, Plans K, L and M, and other letters. They can generally explain what each plan is designed to cover. They may also describe how carriers in your state differ.

A conversation with an agent is usually a chance to talk through your doctors, your travel habits and how comfortable you are with cost-sharing. Helpful questions include: Which carriers sell Plan G in my state? How does my enrollment timing affect my options? Would underwriting apply to me?

An agent may also help you think about Part D drug coverage and how Medigap fits with it. No agent can promise acceptance, savings or a single best plan. Call 1-800-MEDIGAP for more information.

The bigger picture

Choosing a Medicare supplement is about more than numbers. For many people, knowing how their care costs may work brings real peace of mind. Feeling confident in a choice can ease stress, which matters for overall wellbeing.

It can help to take your time and ask questions without pressure. If finding the right doctors or care teams is part of your planning, Providers.plus may be one resource to explore. Always confirm current rules at Medicare.gov, with your State Health Insurance Assistance Program (SHIP), or with a licensed agent.

Keep in mind

  • Plan G is sold to people newly eligible for Medicare; Plans C and F are limited to those eligible before January 1, 2020.
  • Plan H was discontinued and is not sold today, even though people still search for it.
  • Open enrollment, guaranteed issue and underwriting rules vary by state and change over time, so confirm current rules before deciding.
