Medicare Supplement Plan G is a standardized Medigap policy sold by private insurers to cover out-of-pocket costs that Original Medicare (Parts A and B) doesn't pay. The Centers for Medicare & Medicaid Services sets Plan G benefits, so coverage is identical across all insurers. Only premiums differ. Plan G is the most complete Medicare Supplement option for beneficiaries who enrolled in Medicare on or after January 1, 2020, when Plan F closed to new enrollees.

What Is a Plan G Medicare Supplement?
What Does Medicare Supplement Plan G Cover?
Plan G covers eight standardized benefits set by CMS for 2026. These benefits cover the out-of-pocket cost gaps that Original Medicare Parts A and B leave behind, including hospital stays, skilled nursing care and emergency care outside the U.S.
The one gap Plan G doesn't fill is the annual Part B deductible of $283. Once you pay that, Plan G covers approved costs across all eight benefit areas below.
Medicare Part A Co-Insurance and Hospital Costs
Covers all Part A hospital co-insurance costs, including up to 365 extra days of inpatient care after Medicare benefits are used up.
Medicare Part B Co-Insurance or Copay
Pays your 20% share of approved costs for doctor visits, outpatient services and lab tests after Medicare covers its 80%.
Blood: First Three Pints per Year
Covers the cost of the first three pints of blood each calendar year, which Original Medicare doesn't cover.
Part A Hospice Care Co-Insurance or Copay
Covers your share of Medicare-approved hospice services under Part A, including drugs for pain and symptom relief.
Skilled Nursing Facility Co-Insurance
Pays the daily co-insurance of $217 for days 21 to 100 of a Medicare-covered skilled nursing facility stay in 2026, per CMS.gov.
Medicare Part A Deductible
Covers the $1,736 Part A deductible per benefit period in 2026, per CMS.gov, protecting you from repeated hospital billing across benefit periods.
Part B Excess Charges
Pays amounts above the Medicare-approved rate when a provider doesn't accept Medicare assignment. Providers can legally charge up to 15% above the approved rate.
Foreign Travel Emergency Care
Covers 80% of medically necessary emergency care costs outside the U.S. after a $250 deductible, up to a $50,000 lifetime limit.
What Are the Pros and Cons of Medicare Supplement Plan G?
Many people choose Plan G for its wide cost coverage and fewer unexpected out-of-pocket expenses than most other Medigap plans. It costs more per month than lower-tier options and doesn't cover the Part B deductible or prescriptions. How often you use health care and whether your providers accept Medicare assignment should guide your decision on whether the added cost makes sense.
Benefits and Disadvantages of Plan G
- Covers the Part A deductible ($1,736 per benefit period in 2026), protecting you from repeated hospital billing if multiple benefit periods begin in a single year
- Pays Part B excess charges that Plan N skips, valuable if you see specialists who don't accept Medicare assignment
- Accepted by any doctor or hospital nationwide that accepts Medicare with no network restrictions
- No referrals needed to see any specialist
- Covers 80% of emergency medical costs abroad after a $250 deductible, up to a $50,000 lifetime limit
- Doesn't cover the Part B deductible ($283 in 2026), which you pay out of pocket each year
- Monthly premiums rise with age under Attained Age Pricing, the most common pricing method
- Doesn't include prescription drugs and requires a separate Part D plan for medications
- Higher monthly premiums than Plan N for beneficiaries who rarely see out-of-assignment doctors
- Not available to beneficiaries who enrolled in Medicare before January 1, 2020; Plan F may apply to those enrollees
How Much Does Medicare Supplement Plan G Cost?
Premiums for Plan G vary by age, insurer and pricing method. Three pricing structures affect how much you pay now and how costs change over time. MoneyGeek's 2026 rate analysis shows average monthly costs range from $196 to $306 for 65-year-olds and $262 to $327 for 75-year-olds.
Compare multiple insurers during your Medigap Open Enrollment Period to see how Plan G costs compare across all three pricing methods in your state.
65 | $196/month | $239/month | $306/month |
75 | $262/month | $313/month | $327/month |
*Attained Age Pricing starts lowest but rises annually as you age. With Issue Age Pricing, your rate locks in at enrollment and won't increase just because you get older. Community Pricing charges every enrollee in a geographic area the same rate regardless of when they sign up.
How Is Medicare Supplement Plan G Different from Plan F and Plan N?
Three of the most common Medigap options include Plan G, Plan F and Plan N, each covering a different set of cost gaps. Plan F offers the most complete coverage but isn’t available to those who became eligible for Medicare on or after January 1, 2020.
Plan N comes with a lower monthly premium, though it still requires copays for doctor and emergency room visits and doesn't cover Part B excess charges. Plan G fills more gaps than Plan N and remains available to all current Medicare beneficiaries.
Part B deductible covered | Yes | No | No |
Part B excess charges covered | Yes | Yes | No |
Part B co-insurance covered | Yes | Yes | Yes (with copays) |
Office visit copay | None | None | Up to $20 |
Emergency room copay | None | None | Up to $50 |
Skilled nursing facility co-insurance | Yes | Yes | Yes |
Foreign travel emergency care | Yes | Yes | Yes |
Available to 2020+ enrollees | No | Yes | Yes |
Is Medicare Supplement Plan G Right for You?
Plan G suits people who want wide coverage without dealing with network limits or referral requirements. It works well if you visit specialists often, travel outside the country or expect more frequent hospital care.
The higher premium may not make sense if you’re in good health and don’t need that level of coverage. In that case, Plan N offers a lower monthly cost while still covering most of the gaps in Medicare.
New Medicare Enrollees (Eligible January 1, 2020 or Later)
Plan G is the most complete Medigap option available to new enrollees, covering all Original Medicare gaps except the $283 annual Part B deductible.
Frequent Specialist Visitors
One key difference is coverage for Part B excess charges, which Plan N doesn't include, so you avoid extra billing when a specialist doesn’t accept Medicare assignment.
International Travelers
Coverage includes 80% of medically necessary emergency care outside the U.S. after a $250 deductible, up to a $50,000 lifetime limit.
People With Frequent Hospital Stays
Your Part A deductible of $1,736 per benefit period in 2026 is covered under Plan G, per CMS.gov, protecting you if multiple benefit periods begin in a single year.
Beneficiaries Who Want No Network Restrictions
Plan G is accepted by every Medicare-participating provider in the country. No referral or prior authorization is required to see any specialist.
CONSIDER OTHER OPTIONS: PLAN N, HIGH DEDUCTIBLE PLAN G, PLAN F AND MEDICARE ADVANTAGE
Plan G isn't the only way to fill Original Medicare's cost gaps. Depending on your health care use, budget and location, these alternatives may serve you better:
- Plan N costs less per month than Plan G and covers the Part A deductible, skilled nursing facility co-insurance and most Part B co-insurance. It applies copays of up to $20 for office visits and up to $50 for emergency room visits and doesn't cover Part B excess charges. MoneyGeek's best Medicare Supplement plans comparison shows Plan N carries lower average rates than Plan G for both 65- and 75-year-olds.
- High Deductible Plan G carries a lower monthly premium in exchange for paying the first $2,950 of Medicare-approved costs yourself in 2026, per CMS.gov. Once you meet that deductible, coverage works identically to standard Plan G. This option works well for beneficiaries who are in good health and want a lower monthly payment with a predictable annual out-of-pocket cap.
- Medicare Advantage (Part C) replaces Original Medicare with an all-in-one plan that often includes drug, dental and vision coverage. It uses provider networks and may require referrals. Unlike Medigap, Medicare Advantage plans require annual enrollment review. The best Medicare Advantage plans vary widely by state, so compare local options alongside Medigap before deciding.
- Plan F covers everything Plan G covers plus the Part B deductible of $283 in 2026. It's only available to beneficiaries who were eligible for Medicare before January 1, 2020. If you enrolled before that date, Plan F may lower your annual out-of-pocket costs if the premium difference with Plan G is less than $283 per year.
