Medicare’s standard Part B deductible rises to $283 in 2026, an increase of $26 from $257 the year before. It is the amount a beneficiary must cover out of pocket before Original Medicare begins paying its share of doctor visits, outpatient care, lab work, and durable medical equipment. Unlike the Part A hospital deductible, which can recur several times a year, the Part B deductible is charged only once per calendar year, making it a smaller but far more predictable line in a retiree’s health budget.
What the $283 deductible covers before Medicare pays
Part B is the outpatient side of Original Medicare, covering physician services, preventive screenings, outpatient hospital care, and equipment such as wheelchairs and walkers. According to Medicare’s summary of what Part B covers, those services run through a single annual deductible before the program pays anything toward them. The $283 threshold applies uniformly to standard enrollees regardless of which covered services they use first.
Once the deductible is met, cost-sharing does not stop. Medicare then pays its portion and the beneficiary typically owes 20 percent of the Medicare-approved amount for each covered service, an open-ended coinsurance with no annual cap under Original Medicare. That means the $283 is the entry point rather than the ceiling: a year of frequent specialist visits or outpatient procedures can generate coinsurance many times the size of the deductible itself.
The once-a-year structure is what sets Part B apart from Part A. Medicare’s official cost breakdown states that the $283 is paid a single time each calendar year, after which the deductible resets only on January 1. For most retirees the deductible is cleared early in the year through routine care, and the coinsurance that follows becomes the more meaningful cost.

How the deductible fits with the $202.90 monthly premium
The deductible is separate from the monthly premium that every Part B enrollee pays. For 2026 the standard premium is $202.90, an increase of $17.90 from $185.00, according to the CMS 2026 premiums and deductibles fact sheet. Together, the higher premium and the higher deductible mean a standard beneficiary who uses Part B services will pay more up front in 2026 than in 2025 on both counts.
Higher earners pay more than the standard premium through the income-related monthly adjustment amount, which affects roughly 8 percent of Part B enrollees. Those surcharges begin above modified adjusted gross income of $109,000 for an individual and $218,000 for a couple, pushing the total monthly premium as high as $689.90 at the top income tier. The $283 deductible, by contrast, does not vary by income; it is the same for every standard enrollee.
The surcharge climbs in five income steps rather than all at once. The first tier adds $81.20 a month for an individual just above $109,000, lifting the total premium to $284.10, and each higher bracket adds more until the top tier, individuals at or above $500,000 or couples at or above $750,000, pays a $487.00 surcharge for a $689.90 monthly premium. Because those brackets rest on modified adjusted gross income reported two years earlier, a one-time jump in income, such as a large Roth conversion or the sale of a home, can push a retiree into a higher premium tier well after the money was received, an effect that surprises many first-time enrollees.
That distinction matters for planning. The premium is a fixed monthly cost that can scale with income, while the deductible is a one-time annual hurdle that is identical across the board. A retiree comparing years should track both, because a rising premium and a rising deductible together raise the floor of Part B spending even before any coinsurance is added.
Why the annual deductible rose $26 for 2026
CMS attributes the 2026 increase in both the premium and the deductible mainly to projected price changes and assumed increases in the use of medical services, consistent with historical patterns. The agency also noted that action to curb spending on skin substitutes held the premium increase roughly $11 a month lower than it would otherwise have been, an unusual case of a policy change directly restraining a Medicare cost figure.
That skin-substitutes adjustment is more consequential than it first appears. CMS said spending on the wound-care products had surged and is now expected to fall about 90 percent under the 2026 Physician Fee Schedule without affecting patient care, which is why a single line of policy shows up in the premium math. A separate statutory shield, the hold-harmless provision, keeps most enrollees whose premiums are deducted from Social Security from seeing that deduction rise by more than their dollar cost-of-living raise, though the highest earners subject to the income surcharge and beneficiaries new to Part B are not protected by it and absorb the full increase.
The $26 rise continues a steady upward march in the Part B deductible, which reflects the broader cost of outpatient medicine rather than any single program change. Because the deductible is recalculated each year under a formula set in the Social Security Act, it moves with projected Part B spending rather than with the consumer inflation measure that governs Social Security’s cost-of-living adjustment.
For the standard enrollee, the practical result is a modest but real increase in the cost of entering Part B coverage for the year. The $283 is small next to a serious medical event, yet it is the first dollar figure every beneficiary encounters, and its annual climb is a reliable signal of where outpatient costs are heading across the Medicare program.
