Original Medicare’s Part B deductible is a yearly threshold, not a monthly premium and not a hospital deductible. For 2026, Medicare lists the deductible at $283 and says it is paid once each year before Original Medicare begins to pay. The rule affects covered medical services and items under Part B, then gives way to the program’s separate coinsurance rules.
The $283 Is a Once-a-Year Part B Amount
On its 2026 cost page, Medicare places the $283 figure in the Part B table and describes it as a deductible paid once each year. Part B is medical insurance, which commonly includes physician services, outpatient care and certain medical equipment. The deductible is therefore distinct from the Part A deductible for inpatient hospital benefit periods.
Calling both amounts “the Medicare deductible” can obscure the difference. Part A’s published $1,736 deductible attaches to an inpatient benefit period, while Part B’s $283 amount is annual. A person can encounter either, both, or neither depending on the service and coverage arrangement.

Coinsurance Usually Follows the Deductible
Medicare.gov says the general Part B cost for a covered service or item is usually 20% after the deductible has been paid, when the doctor or other provider accepts the Medicare-approved amount as full payment. The deductible does not replace coinsurance; it is the first step in the cost-sharing sequence.
The word “usually” is material. Some services have different cost rules, and coverage can vary by the kind of service, provider setting and supplemental insurance. The 20% general rule should not be used as a quote for every procedure, but it explains why meeting the annual deductible does not mean subsequent covered Part B care is cost-free.
Premiums Are a Third Part of the Cost Picture
In 2026, the standard Part B premium is $202.90 a month, with higher amounts for some people based on income. The premium continues even during months when no Part B service is used. It is separate from the $283 deductible and separate again from the coinsurance after the deductible.
Those three terms describe different timing. The premium is recurring coverage cost, the deductible is the annual amount paid before Original Medicare starts to pay for Part B covered services, and coinsurance is the share that can remain after the deductible. A bill or Medicare Summary Notice should be read with the service date and the beneficiary’s year-to-date deductible status in mind.
Original Medicare Is the Source of the Figure
The headline’s amount applies to Original Medicare. Medicare Advantage plans set plan-specific cost sharing and have their own annual out-of-pocket limits for covered services. A Medigap policy may pay some Original Medicare deductibles or coinsurance, depending on the plan. Those arrangements can change what a person ultimately pays without changing Medicare’s published Part B deductible.
Provider assignment can matter, too. The official table links the 20% general rule to providers that accept Medicare-approved payment as full payment. A charge should therefore be evaluated against the provider’s Medicare participation, the service description and the insurance held alongside Part B.
Cost sharing is also separate from the question of whether Medicare covers a service at all. The annual deductible is a rule for covered Part B services and items; it does not make a noncovered charge payable by Medicare. The agency’s cost table is therefore best read with the underlying benefit description, because the service category determines whether the general Part B sequence applies in the first place.
The Annual Reset Does Not Apply to Every Medicare Charge
January brings a new Part B deductible year, but it does not erase every other Medicare cost rule. Part A has benefit periods, Part D plans have their own premiums and pharmacy terms, and Medicare Advantage or Medigap coverage has separate documents. The annual nature of the $283 figure is specific to the Part B deductible.
Preventive services can also have rules that differ from the general deductible-and-coinsurance sequence. A reader comparing an estimate with a Medicare notice should identify the exact service before assuming the $283 threshold applies in the same way. The official cost page supplies the general rule, while the benefit description controls the service-specific exception.
For 2026, Medicare’s sequence is explicit: the Part B deductible is $283 once per year, then covered services and items usually carry 20% coinsurance after it has been paid. That framing identifies what the number means without treating it as the full cost of receiving medical care.
The Programs That Can Address Part B Costs
Medicare Savings Programs can pay Part B premiums and may help with deductibles, coinsurance and copayments depending on the program. They are state-run and require a separate application rather than an automatic credit on a Part B bill.
