Humana sells all 10 standardized Medicare Supplement plans, each covering different benefits at different costs. Plan availability depends on where you live.
- Plan A: Covers basic Medicare Supplement benefits including Part A coinsurance, Part B coinsurance and three pints of blood annually without covering deductibles or foreign travel.
- Plan B: Includes Plan A benefits plus coverage for the Medicare Part A deductible of $1,736 in 2026.
- Plan C: Delivers comprehensive coverage including both Part A and Part B deductibles, skilled nursing facility coinsurance and foreign travel emergency care, but isn't available to people who became eligible for Medicare on or after Jan. 1, 2020.
- Plan D: Covers the Part A deductible, skilled nursing facility coinsurance and foreign travel emergency care without covering the Part B deductible.
- Plan F: Gives the most comprehensive Medicare Supplement coverage, paying all Medicare deductibles and coinsurance, but isn't available to people who became eligible for Medicare on or after Jan. 1, 2020.
- Plan G: Mirrors Plan F coverage except you pay the annual Part B deductible yourself, making it the most comprehensive plan available to all Medicare beneficiaries.
- Plan K: Covers 50% of most benefits until you reach the annual out-of-pocket limit, after which it pays 100% of covered services.
- Plan L: Covers 75% of most benefits until you reach the annual out-of-pocket limit in, offering middle-ground protection between high-deductible and comprehensive coverage.
- Plan M: Covers 50% of the Part A deductible along with full coverage for Part A and Part B coinsurance and foreign travel emergency care.
- Plan N: Requires you to pay the Part B deductible and modest copays of up to $20 for office visits and up to $50 for emergency room visits while covering most other Medicare expenses.
Humana also has high-deductible versions of Plan F and Plan G, which feature the same benefits with lower monthly premiums but require you to pay a $2,950 deductible in 2026 before coverage begins.
