Choosing a Medicare Supplement plan can be confusing, especially when you want to know which medical expenses you will still have to pay yourself. Medicare Supplement Plan G helps cover many out-of-pocket costs left by Original Medicare, but it does not pay for every healthcare expense. Understanding these benefits and limitations can help you make a more informed decision.
If you are researching AARP Medicare Supplement Plan G, it is important to look beyond the plan’s name and understand precisely which costs it covers, which expenses remain your responsibility, and how its benefits work in real-life situations.
What Is Medicare Supplement Plan G?
Medicare Supplement Plan G, also called Medigap Plan G, is a type of private insurance designed to work alongside Original Medicare, which consists of Medicare Part A (hospital insurance) and Part B (medical insurance).
Original Medicare pays its share of Medicare-covered healthcare services, and you may be responsible for deductibles, coinsurance, or other cost-sharing amounts. Plan G helps pay many of these eligible expenses according to its standardized benefits.
Plan G benefits are standardized in most states, meaning the basic medical benefits are the same regardless of which insurance company sells the policy. However, premiums, pricing methods, discounts, and customer service can differ between insurers.
Plan G is not the same as Medicare Advantage. It supplements Original Medicare rather than replacing it, and it generally does not restrict you to a plan-specific network of doctors when you receive Medicare-covered services from providers who accept Medicare.
What Does Medicare Supplement Plan G Cover?
Plan G provides several important benefits that can reduce your exposure to Medicare cost-sharing expenses.
1. Medicare Part A Hospital Deductible
Plan G covers 100% of the Medicare Part A deductible for eligible covered services.
For 2026, the Part A inpatient hospital deductible is $1,736 per benefit period. Without supplemental coverage for this expense, you could be responsible for that amount when the deductible applies.
For example, if you have a qualifying inpatient hospital admission and owe the $1,736 Part A deductible, Plan G generally covers that deductible, subject to the policy’s terms.
An inpatient hospital admission is different from receiving care in a hospital emergency department or being classified as an outpatient under observation status. The way the hospital classifies your care can affect which Medicare benefits and cost-sharing rules apply.
2. Medicare Part A Hospital Coinsurance and Additional Hospital Benefits
Plan G covers Medicare Part A hospital coinsurance and provides coverage for up to an additional 365 days of hospital costs after Original Medicare hospital benefits are exhausted, subject to the policy’s terms.
This benefit can be valuable for people who experience extended hospital stays. It does not mean every expense associated with a hospital stay is covered; the service must qualify under applicable Medicare and Medigap rules.
3. Medicare Part B Coinsurance or Copayments
Medicare Part B covers eligible outpatient medical services, including many physician visits, diagnostic tests, outpatient procedures, and medically necessary services.
After you meet the applicable Part B deductible, Original Medicare generally pays 80% of the Medicare-approved amount for covered Part B services, leaving you responsible for the remaining 20% coinsurance.
Plan G covers 100% of eligible Medicare Part B coinsurance or copayments after you meet the Part B deductible.
For example, suppose Medicare approves a covered outpatient service for $500. After you have met your Part B deductible, Original Medicare generally pays $400, leaving $100 in coinsurance. Plan G generally pays that eligible $100 balance.
4. Medicare Part B Excess Charges
Some healthcare providers who do not accept Medicare assignment may be permitted to charge more than the Medicare-approved amount for certain Part B services. The additional amount is known as a Part B excess charge, subject to applicable federal and state rules.
Plan G covers 100% of eligible Part B excess charges.
For example, if a provider is legally permitted to bill $120 above Medicare’s approved amount for a covered service, Plan G generally covers that $120 excess charge. Not every provider can charge excess amounts, and some states restrict or prohibit them. You can ask whether a provider accepts Medicare assignment before receiving care.
5. Skilled Nursing Facility Care Coinsurance
Medicare Part A may cover qualifying skilled nursing facility care when specific eligibility and coverage requirements are met. For covered skilled nursing facility care, Medicare generally requires coinsurance for days 21 through 100 of a benefit period. Plan G covers 100% of the applicable Medicare Part A skilled nursing facility care coinsurance.
This benefit does not mean Plan G pays for unlimited nursing home care. Medicare’s qualifying conditions, covered-service rules, and time limits still apply. Long-term custodial care—such as ongoing help with bathing, dressing, or eating when skilled care is not required—is generally not covered by Medicare or Medigap.
6. Medicare Part A Hospice Care Coinsurance or Copayments
For people receiving eligible hospice care under Medicare Part A, Plan G covers the applicable Part A hospice care coinsurance or copayments. The benefit applies to Medicare’s defined hospice cost-sharing, not every expense that a patient or family might incur while arranging end-of-life care.
7. The First Three Pints of Blood
Plan G covers the cost-sharing for the first three pints of blood for a covered medical service, as specified by the standardized benefit. This benefit may be relevant during surgery, treatment for certain conditions, or other medical situations involving a blood transfusion.
8. Emergency Medical Care During Foreign Travel
Original Medicare generally provides very limited coverage for healthcare received outside the United States. Plan G includes a limited foreign-travel emergency medical benefit.
Under the standardized benefit, eligible emergency medical care received outside the United States is covered at 80% after a $250 annual deductible, subject to a $50,000 lifetime maximum and the plan’s other conditions.
Important limitations apply:
- The emergency must meet the policy’s definition of a covered medical emergency.
- The benefit generally applies during the first 60 days of a trip outside the United States.
- You are responsible for the applicable deductible and the remaining 20% of covered expenses.
- The $50,000 lifetime limit applies to the foreign-travel emergency benefit. Routine medical care abroad and every possible travel-related expense are not automatically covered.
If you travel internationally, check your policy’s full terms and consider whether separate travel medical insurance is appropriate for your trip.
What Does Medicare Supplement Plan G Not Cover?
Although Plan G provides substantial protection against Medicare cost-sharing, several important expenses remain outside its standard benefits.
1. The Medicare Part B Annual Deductible
Plan G does not cover the Medicare Part B deductible. You must pay eligible Part B expenses yourself until you have met the annual deductible.
For 2026, the Medicare Part B deductible is $283.
For example, if you have not met your Part B deductible and receive a covered service with a Medicare-approved amount of $200, you may need to pay that $200 toward the deductible. If you later receive another eligible service costing $183, you may pay the remaining $83 to meet the deductible. Once the deductible is met, Plan G generally covers eligible Part B coinsurance for the remainder of the applicable coverage period.
The exact amount you owe depends on the services received and how Medicare applies the deductible.
2. Prescription Drug Coverage
Medicare Supplement Plan G does not include outpatient prescription drug coverage.
If you need coverage for medications obtained from a pharmacy, you can consider enrolling in a separate Medicare Part D prescription drug plan, subject to enrollment rules. Without appropriate drug coverage, you may have to pay the full cost of your outpatient prescriptions, depending on the medication and any other coverage you have.
Before selecting a Part D plan, compare the drugs on your medication list, pharmacy options, premiums, deductibles, and cost-sharing requirements.
3. Routine Dental, Vision, and Hearing Services
Standard Medigap Plan G benefits do not cover routine dental care, routine vision services, eyeglasses, or hearing aids.
For example, you should not assume the policy will pay for:
- Routine dental cleanings, fillings, or dentures.
- Routine eye examinations or prescription glasses.
- Hearing tests or hearing aids when not covered by another applicable benefit.
Some AARP-branded Medicare Supplement offerings may advertise additional wellness services or discounts. These extras are distinct from the standardized Plan G medical benefits, and their availability and terms depend on the particular offering. A discount is not the same as insurance coverage that pays the bill.
If these services are important to you, investigate separate coverage options and review what each policy actually pays.
4. Long-Term Custodial Care
Plan G is not long-term care insurance.
It does not pay for ongoing custodial care simply because a person needs assistance with everyday activities such as dressing, bathing, eating, or moving around. Medicare may cover qualifying skilled nursing facility care under specific conditions, but that is different from paying for a long-term nursing home stay or ongoing personal care at home.
People planning for future care needs should evaluate these potential expenses separately rather than assuming a Medigap policy will cover them.
5. Healthcare Services That Original Medicare Does Not Cover
Medigap generally supplements Original Medicare; it does not transform an excluded service into a covered Medicare benefit. If Original Medicare does not cover a service, Plan G generally will not pay for it simply because you have the supplement.
For example, routine dental care, most routine eye care, and most hearing aids are not covered under Original Medicare. There may be exceptions where Medicare covers a particular service under specific medical circumstances, so check the rules for the exact treatment you need.
6. Your Plan G Premium
Your monthly insurance premium is separate from the medical expenses that Plan G covers. You must continue paying the policy premium to maintain coverage, even in months when you do not visit a doctor or use medical services.
Your premium can vary based on factors such as location, insurer pricing method, age-related pricing rules, and available discounts. Premiums can also increase over time.
When comparing plans, evaluate both the monthly premium and the out-of-pocket costs you may still incur. A policy with a lower premium is not necessarily the most economical choice for every person.
How Plan G and Original Medicare Work Together: A Practical Example
Consider a beneficiary who has Original Medicare and a standard Plan G policy in 2026. The beneficiary receives a Medicare-covered outpatient service with an approved cost of $1,000 and has already met the annual Part B deductible.
- Original Medicare Part B pays: generally $800, or 80% of the approved amount.
- The remaining Part B coinsurance: $200.
- Plan G pays: generally the eligible $200 coinsurance.
- The beneficiary pays for that service: $0 in Part B coinsurance, assuming the service is covered, the deductible has already been met, and no other exclusions or special circumstances apply.
Now consider a different situation: the beneficiary has not yet met the $283 Part B deductible. The deductible may apply first, and the beneficiary remains responsible for meeting it. Plan G does not pay that deductible.
These examples illustrate why it is important to distinguish between the annual deductible and the coinsurance that may apply afterward. They also demonstrate why Plan G should not be described as completely free healthcare. The beneficiary still pays the monthly premium, the Part B deductible, and expenses that fall outside the policy’s benefits.
Is Medicare Supplement Plan G Right for You?
Plan G may be worth considering if you want predictable cost-sharing for many Medicare-covered services and are comfortable paying the monthly premium and annual Part B deductible.
It may be particularly useful for people who:
- Want coverage for many eligible hospital and outpatient cost-sharing expenses.
- Prefer Original Medicare’s access to providers who accept Medicare, without a Medigap-specific network restriction.
- Want coverage for eligible Part B excess charges.
- Are comfortable arranging separate prescription drug coverage when needed.
- Understand that dental, vision, hearing, and long-term custodial care may require separate financial planning.
However, Plan G is not automatically the best choice for everyone. Compare its premiums with other available Medigap plans, such as Plan N, and consider your healthcare needs, financial situation, and tolerance for potential out-of-pocket expenses.
Before switching from another Medigap policy, check whether medical underwriting may apply and whether you qualify for guaranteed-issue protections. Do not cancel an existing policy until you understand the eligibility rules and have confirmed the arrangements for replacement coverage.
Questions to Ask Before Enrolling in Plan G
Before purchasing a policy, ask the insurer or a licensed insurance professional:
- What is my monthly premium, and how might it change over time?
- Which pricing method does the insurer use in my state?
- Does the policy cover the standardized Plan G benefits, and are any additional benefits included?
- How does the policy handle foreign-travel emergency claims and exclusions?
- Are any pre-existing-condition waiting periods applicable to my situation?
- What enrollment rules or medical underwriting requirements apply?
- What separate arrangements will I need for prescription drugs, dental care, vision care, and hearing aids?
Review the policy’s Outline of Coverage and other required documents before enrolling. These materials can help you understand the actual terms rather than relying only on a summary or advertisement.
