Understanding the 10 Standard Medigap Plans

Medigap plans are available for private healthcare insurers in all 50 states. Not all providers operate in all states, and there are limitations on the availability of high-deductible plans in some states as well.

There are ten Medigap plans, and the Federal government regulates the benefits provided by each plan sold by insurers. As a result, there’s consistency in the plans available for all providers across the country.

Plan F & G have “high-deductible” options, giving you the opportunity to benefit from the comprehensive coverage they offer, but at a lower premium cost each month. Plans K, L, M, and N have cost-sharing components like copayments and coinsurance responsibilities.

Every insurer must offer Plan A, but it has the most basic level of coverage.

Basic Medigap Benefits Across All Plans

All Medigap plans provide some level of coverage for the following out-of-pocket medical expenses incurred by beneficiaries.


Medicare Part A – Hospitalization

Medigap covers the copayments required for hospitalization in inpatient care services from day 61 onwards until the end of the Medicare benefits period. It covers the Medicare Part A copayments for any hospital stay over the 90th day in the benefit period, up to an extra 60 days during your lifetime, otherwise known as your “inpatient reserve days.”

Part A Hospitalization Medigap Offers...

Beneficiaries can use these reserve days when they must spend more than 90 days in the hospital during any benefit period. When using a reserve day, it’s subtracted from the lifetime total.

Medigap pays your Medicare Part A coinsurance and offers coverage for 365 days after your Medicare benefits end. Medigap also covers coinsurance costs for care at skilled nursing facilities.


Medicare Part A – Hospice Care

Medigap pays copayments for outpatient medications for pain control and inpatient respite care costs. Plan K & L contribute to these costs at different rates.

However, you must acquire a certificate of terminal illness from your doctor to meet the Medicare requirements for this coverage.


Medigap Pays the 20% for Part B coinsurance Part B – Medical Expenses

After meeting the Part B deductible of $226 for 2023, Medigap pays the 20% Part B coinsurance for your doctor consultations, home or hospital care, and other eligible expenses.

Plans K, L, & N require copayments for these services.



Medicare only plays for the fourth pint of blood onwards in procedures.

Medigap covers you for the first three pints under Parts A & B.


Part A and B Deductibles

Part A & B Deductibles

Plans B, C, D, F, G, & N pay the Part A deductible of $1,600 for 2023. Plans K, L, & M pay a portion of the Part A deductible.

K & L have out-of-pocket limits, while the rest of the plans have unlimited coverage for out-of-pocket expenses.

Plan N requires you to make a $20 copayment when visiting the doctor and a $50 copayment on trips to the emergency room that don’t result in hospitalization. Plans C & F are the only options for paying the $226 Part B deductible.

Plans C, D, F, G, M, & N pay for care at skilled nursing facilities with copayments from the 21st to the 100th day in your benefit period under Medicare Part A. This doesn’t qualify as custodial care.

Plans K & L pay portions of the cost until you meet your out-of-pocket limits. The plan then pays 100% of these costs.


Emergency Care During Foreign Travel

Medigap plans C, D, F, G, M & N pay for 80% of emergency care costs when traveling outside the US.

There’s a $250 deductible and a lifetime benefit maximum of $50,000.
