What Medicare Plan G Covers in 2026

For millions of Americans enrolled in Original Medicare, the gap between what the federal program pays and what providers charge can leave large bills. Medicare Supplement Plan G, also known as Medigap Plan G, addresses many of these gaps by covering specific out-of-pocket expenses. However, the plan does not cover every medical cost. It leaves certain expenses, such as the annual Part B deductible and prescription drugs, to the individual or separate insurance policies.

The structure of Medicare coverage has evolved over time. Original Medicare consists of Part A for hospital insurance and Part B for medical insurance. These parts pay a set share of covered services, leaving beneficiaries responsible for deductibles, coinsurance, or copayments. Plan G was designed to supplement these parts rather than replace them. It is distinct from Medicare Advantage, which often involves network restrictions and different cost structures. With Plan G, beneficiaries generally can see any doctor who accepts Medicare without navigating a specific provider network.

The benefits of Plan G are standardized in most states. This means the core medical coverage is identical regardless of which private insurance company sells the policy. While the underlying benefits remain constant, the premiums, pricing methods, and customer service levels vary by insurer. For the 2026 coverage year, the plan addresses specific financial liabilities that arise during medical treatment.

One of the primary features of Plan G is the coverage of the Medicare Part A hospital deductible. In 2026, this deductible is set at $1,736 per benefit period. If a beneficiary requires an inpatient hospital admission, Plan G generally covers this full amount. The plan also covers 100% of the Part A hospital coinsurance. Additionally, it provides coverage for up to 365 extra days of hospital care after the original Medicare benefit period is exhausted. This protection is relevant for extended stays that would otherwise result in high daily costs for the patient.

For outpatient services under Part B, the plan covers 100% of eligible coinsurance and copayments. Once the annual Part B deductible is met, Original Medicare typically pays 80% of the approved amount for covered services. Plan G pays the remaining 20%. It also covers Part B excess charges, which are amounts some providers may charge above the Medicare-approved rate. This benefit applies if the provider is legally permitted to bill such excess amounts under federal and state rules.

The plan includes specific protections for skilled nursing facility care and hospice services. It covers 100% of the applicable coinsurance for days 21 through 100 of a skilled nursing facility stay. It also pays the coinsurance or copayments associated with eligible hospice care under Part A. For blood transfusions, Plan G covers the cost-sharing for the first three pints of blood used in a covered medical service. These benefits apply to acute medical needs rather than long-term custodial care.

For those who travel abroad, Plan G offers a limited emergency medical benefit. It covers 80% of eligible emergency expenses incurred outside the United States after a $250 annual deductible is met. This benefit is subject to a $50,000 lifetime maximum and generally applies only during the first 60 days of a trip. The policy defines what constitutes a covered medical emergency, and routine care abroad is not included in this calculation.

Several expenses remain the responsibility of the beneficiary. Plan G does not cover the Medicare Part B annual deductible, which is $283 for 2026. Beneficiaries must pay this amount out of pocket before the plan begins covering Part B coinsurance. The plan also does not include outpatient prescription drug coverage. Individuals who need medication must enroll in a separate Medicare Part D plan or pay for drugs privately. Routine dental, vision, and hearing services are also excluded from standard Plan G benefits.

Long-term custodial care is not covered by Plan G. The plan is not a substitute for long-term care insurance. It does not pay for ongoing assistance with daily activities such as bathing, dressing, or eating when skilled medical care is not required. If Original Medicare does not cover a specific service, Plan G generally will not pay for it. Beneficiaries must continue to pay their monthly premiums to maintain coverage, even in months when they do not use medical services.
