What it is
Medicare Plan G is a Medigap policy. Medigap plans are sold by private insurers to people who have Original Medicare (Part A and Part B). Each lettered plan has a standardized set of benefits, so Plan G generally offers the same core benefits no matter which company sells it, though the companies themselves can differ in how they price and service it.
Plan G is generally understood to cover many of the cost-sharing gaps in Original Medicare, such as Part A hospital coinsurance and Part B coinsurance. It typically does not cover the Part B deductible, which the enrollee usually pays. It does not include prescription drug coverage, so people often add a separate Medicare Part D drug plan. Plan G also does not typically cover things like routine dental, vision or hearing, so those are worth checking.
Medigap plans work only alongside Original Medicare. They are not the same as Medicare Advantage (Part C), and you generally cannot use both at once. Because plan rules, availability and benefits can change, check Medicare.gov or speak with a licensed agent for current details.

How it’s traditionally been approached
Many people who want predictable cost-sharing and the freedom to see any doctor or hospital that accepts Medicare have looked at Medigap plans, including Plan G. Because Medigap works with Original Medicare, there is generally no provider network to stay within, which some people value when they travel or see specialists in different places.
The trade-offs are also worth weighing. Medigap premiums are generally higher than the premiums for many Medicare Advantage plans, and outside of open enrollment or certain guaranteed-issue periods, insurers in many states may use medical underwriting, which could affect whether you are accepted. Medigap also requires a separate Part D plan for drug coverage.
Others have traditionally preferred Medicare Advantage, which bundles hospital and medical coverage and often includes drug coverage and extra benefits such as dental, vision or hearing. Its trade-offs can include provider networks, prior authorization requirements, and cost-sharing that varies by plan. Neither path is right for everyone, and the better fit depends on a person's health needs, budget, doctors and preferences.
How the right agent may help
A licensed independent agent may help you understand how Plan G fits alongside Original Medicare, and how it compares with other Medigap letters and with Medicare Advantage. Since Medigap plan letters are standardized, an agent may help you focus on differences between carriers, such as service, rate-setting practices and how premiums may change over time, without promising any particular result.
A conversation with an agent is generally a chance to talk through your doctors, prescriptions, travel habits and budget comfort. Helpful questions to ask include: Which carriers are you appointed with? Do you represent more than one company? How does underwriting work for me right now? Does my enrollment timing matter? What would I need for drug coverage? How might premiums change in the future?
Insurance agents must be licensed in each state where they sell, and Medicare plans are sold by agents appointed with each carrier. Confirm any agent's license with your state insurance department. Ask for quotes in writing and compare terms directly with the carrier before deciding. A good agent may help you ask questions, but cannot guarantee acceptance, savings or that any plan is the best choice.
The bigger picture
Choosing Medicare coverage is about more than paperwork. Many people feel stress about unexpected medical bills or about whether their doctors will be covered. For some, the appeal of a plan like Plan G is the peace of mind that comes from knowing what to expect, while others prefer a different balance of premium and benefits. How you feel about uncertainty and cost matters as much as the plan details.
Taking time to understand your options may help you feel more at ease and make it easier to focus on your health and daily life. If you are also looking for care, directories such as Providers.plus may help you find providers. Whatever you choose, coverage is open to everyone regardless of background or views, and you are free to compare approaches at your own pace.
Keep in mind
- Plan G is a Medigap plan; it only works with Original Medicare and does not include drug coverage.
- Medigap premiums, underwriting rules and availability vary by carrier, state and enrollment timing, so confirm current details with a licensed agent or Medicare.gov.
- Plans C and F are available only to people who were eligible for Medicare before 1 January 2020, so they are not options for most new enrollees.
- 2A Benefit is an independent directory, not an insurer, and does not sell policies; licensed agents provide quotes, and nothing here is advice.

Frequently asked questions
What is Medicare Plan G?
Medicare Plan G is a standardized Medicare Supplement (Medigap) plan sold by private insurers. It is designed to help pay certain costs Original Medicare leaves, such as many coinsurance amounts. It does not include prescription drug coverage.
Does Medicare Plan G cover the Part B deductible?
Plan G generally does not cover the Medicare Part B deductible, so the enrollee typically pays it. Other cost-sharing gaps are generally covered, but details can change. Confirm current benefits with Medicare.gov or a licensed agent.
Is Medicare Plan G the same from every company?
The core benefits of Plan G are standardized, so they are generally the same across companies. Carriers can differ in how they price the plan, how premiums change over time, and in customer service. Compare terms directly with each carrier.
Can I get Medicare Plan G with a Medicare Advantage plan?
No, Medigap generally cannot be used together with a Medicare Advantage plan. Medigap works with Original Medicare only. A licensed agent can explain what switching between them may involve.
Do I need a separate drug plan with Medicare Plan G?
Yes, most people with Plan G add a separate Medicare Part D prescription drug plan, since Medigap plans sold today do not include drug coverage. An agent can help you understand how the two fit together.
Can I be turned down for Medicare Plan G?
It is possible. Outside of open enrollment or certain guaranteed-issue periods, insurers in many states may use medical underwriting and could decline an application. Rules vary by state, so check with a licensed agent or your state insurance department.
