Among the ten standardized Medigap policies sold to people on Original Medicare, Plan N occupies a middle lane: it covers most of what the richer plans cover, then hands part of the savings back to the enrollee in the form of small copayments. A Plan N holder pays up to $20 for many doctor visits and up to $50 for an emergency room trip that does not end in a hospital admission. In exchange, the monthly premium typically runs below what a fuller plan such as Plan G charges. That structure rewards retirees who see a doctor only occasionally and penalizes almost no one who stays healthy.
How Plan N handles the Part B copayments
Medigap plans are standardized by federal and state law, so the benefits inside Plan N are identical no matter which insurer sells it; only the price and service differ. Plan N pays 100 percent of the Part B coinsurance — the 20 percent of the Medicare-approved amount a beneficiary would otherwise owe after meeting the deductible — with two carved-out exceptions. CMS set those exceptions at the lesser of $20 or the coinsurance for each covered office visit, and the lesser of $50 or the coinsurance for each covered emergency room visit.
The emergency room copayment disappears when the visit leads to an inpatient admission, because the care then shifts to Medicare Part A rather than Part B. A stop at an urgent care clinic carries no Plan N copayment at all, since those visits are billed under a separate code that is neither an office visit nor an emergency room visit. The copay also applies only to the office-visit charge itself, not to the lab work, X-rays, or equipment a doctor orders during the same appointment.
Beyond the two copayments, Plan N still carries the core Medigap protections that make supplemental coverage worth buying. It pays the Part A hospital coinsurance and an extra 365 days of hospital costs after Medicare’s benefits run out, the Part A deductible, skilled nursing facility coinsurance, the first three pints of blood, and hospice coinsurance. It also covers 80 percent of emergency care during foreign travel up to the plan’s limits. The copayments apply narrowly to routine outpatient and emergency visits, not to the large hospital bills that supplemental coverage exists to blunt.

The bills Plan N does not pick up
Two gaps separate Plan N from the most complete Medigap coverage, and both matter when a retiree compares plans. Plan N does not pay the annual Part B deductible, which Medicare set at $283 for 2026; the enrollee covers that amount out of pocket before the plan’s coinsurance help begins. The older Plan F and Plan G treat that first slice of spending differently, so the comparison often turns on how each plan handles the deductible rather than on the headline premium.
Plan N also leaves Part B excess charges to the patient. An excess charge arises when a doctor does not accept Medicare’s approved amount as full payment and bills up to 15 percent more, a practice allowed for providers who do not accept assignment. Plan G and Plan F absorb those excess charges; Plan N does not. In states that prohibit excess charges outright the gap is moot, but elsewhere a retiree who relies on non-participating specialists could face bills a costlier plan would have covered.
Plan N’s place in the market is partly a matter of federal timing. The Medicare Access and CHIP Reauthorization Act of 2015 barred newly eligible beneficiaries from buying any Medigap policy that pays the Part B deductible, which closed Plan F and Plan C to anyone who reached Medicare eligibility on or after January 1, 2020. Plan N, because it leaves that deductible to the enrollee, was untouched and stays open to new enrollees, so it and Plan G are the fuller supplements a retiree turning 65 today can actually buy.
The plan’s protections also carry fixed federal limits worth reading before enrolling. Its foreign-travel emergency benefit pays 80 percent of billed charges for qualifying care abroad only after a separate $250 annual deductible, and it stops at a $50,000 lifetime maximum. Like every Medigap policy, Plan N pays nothing toward prescription drugs, so an enrollee still needs a stand-alone Part D plan, and it sets no annual out-of-pocket ceiling of the kind built into the leaner Plan K and Plan L. Those boundaries define what the lower premium does and does not buy.
Who the premium tradeoff tends to favor
The case for Plan N rests on arithmetic that varies by household. A lower monthly premium compounds over a full year, and for a retiree who visits a physician a handful of times, the accumulated copayments rarely erase that saving. Someone managing a chronic condition with frequent specialist visits, by contrast, can watch the $20 charges add up until a plan with no copays looks cheaper overall.
Because every insurer sells the same standardized Plan N, the shopping decision reduces to premium, pricing method, and company stability rather than the benefit chart. Medicare notes that insurers price Medigap policies by one of three methods — community-rated, issue-age-rated, or attained-age-rated — and the method determines how steeply the premium climbs as the policyholder ages. A quote that looks low at 65 can rise faster under attained-age pricing than a slightly higher community-rated premium.
Timing also shapes the tradeoff. During the six-month Medigap open enrollment period that begins when someone is 65 and enrolled in Part B, an insurer cannot deny coverage or charge more for health history. Outside that window, medical underwriting can apply, so a retiree who chooses Plan N to save on premiums and later wants to switch to fuller coverage may find the door harder to open. The copay-for-premium bargain, in other words, is easiest to enter and hardest to reverse at exactly the moment it is first offered.
