Medicare Supplement Plan L offers a unique way to manage healthcare costs: it pays 75 % of most cost‑sharing requirements for hospital and medical services and includes a built‑in out‑of‑pocket limit. In 2025, that limit is $3,610. Once a beneficiary’s cost‑sharing for Medicare‑approved services reaches this amount, Plan L pays 100 % of covered expenses for the rest of the year.
Plan L covers 75 % of the Part A coinsurance and hospital costs for an additional 365 days after Medicare benefits are exhausted; 75 % of the Part A deductible; 75 % of hospice care coinsurance; 75 % of the first three pints of blood; and 75 % of skilled nursing facility coinsurance. It does not cover the Part B deductible, Part B excess charges or foreign travel emergencies. After the out‑of‑pocket limit is reached, the plan covers 100 % of Medicare‑approved costs for the remainder of the year. This structure protects beneficiaries from catastrophic costs while keeping monthly premiums lower than more comprehensive plans.
Because it pays only three‑quarters of most cost‑sharing, Plan L is best suited for individuals who want to cap their financial exposure but are willing to pay a portion of costs up to the annual limit. The plan’s premiums are generally lower than those of Plan G or Plan D but higher than those of high‑deductible Plan G. As with other Medigap plans, premiums vary based on rating methods (community rated, issue‑age rated or attained‑age rated), and insurer choice can significantly influence long‑term affordability.
Plan L does not include ancillary benefits such as dental or vision coverage, and it does not pay for prescription drugs. Beneficiaries who need these services must purchase separate plans or pay out of pocket. The plan is often compared with high‑deductible Plan G: both have lower premiums and higher potential out‑of‑pocket costs than standard Plan G but differ in how those costs are incurred. Plan L spreads the cost gradually through 25 % coinsurance, while high‑deductible Plan G requires beneficiaries to pay all costs until the deductible is met. Choosing between them depends on personal cash‑flow preferences and risk tolerance.
