What the Part B deductible applies to
The Medicare Part B deductible of $240 applies to the range of medical services that Part B insures. Part B does not cover everything Medicare covers; it specifically handles physicians' services, outpatient hospital care, certain home health visits, durable medical equipment, and other medical services that fall outside Part A's scope. Before Part B begins paying its share of these services in a given year, the beneficiary must first pay out of pocket up to the $240 annual deductible. Once that threshold is met, Part B coinsurance rules apply to additional covered services for the remainder of the calendar year. The deductible is reset each year, and both the deductible amount and the standard monthly premium of $174.70 are set annually under the Social Security Act. Because the deductible applies to the broad set of Part B services - including doctor visits, lab tests, and outpatient procedures - most beneficiaries who use medical care during the year will encounter this cost-sharing requirement before their insurance begins to pay.

Part A has its own separate deductible
Medicare Part A and Medicare Part B each have their own deductible, and the two are entirely separate. Medicare Part A covers inpatient hospitals, skilled nursing facilities, hospice, inpatient rehabilitation, and some home health care services. The Part A deductible applies when a beneficiary is admitted to a hospital and covers the beneficiary's share of costs for inpatient hospital care within a benefit period. The Part B deductible of $240, by contrast, applies to outpatient services such as physician visits, outpatient hospital care, and durable medical equipment. A beneficiary who is hospitalized under Part A and also sees a physician as an outpatient under Part B would face both deductibles independently. The standard monthly premium for Medicare Part B enrollees is $174.70 for 2024, but Part A operates under a different premium structure altogether: most enrollees pay no Part A premium at all because they qualify based on their work history. The two parts of Medicare are designed to cover different types of care, and their cost-sharing rules - including deductibles, coinsurance, and benefit periods - are set separately each year under the Social Security Act.

Why most people pay no Part A premium
Most Medicare beneficiaries never pay a monthly premium for Part A. About 99 percent of Medicare beneficiaries do not have a Part A premium since they have at least 40 quarters of Medicare-covered employment, as determined by the Social Security Administration. Forty quarters roughly equals ten years of work during which payroll taxes were paid toward Medicare. The Social Security Administration evaluates each person's work record to confirm they meet this threshold. Beneficiaries who do not have enough quarters of Medicare-covered employment may still enroll in Part A but must pay a monthly premium for it. For those who qualify, the premium-free Part A enrollment happens automatically in most cases. This work-history rule means that Part A cost-sharing focuses on the deductible and coinsurance rather than on a recurring premium. The annual deductible for Part B is a separate cost: it is $240 in 2024, while the standard monthly Part B premium is $174.70. Thus, a typical beneficiary who qualifies for premium-free Part A still pays the Part B premium and must meet the Part B deductible before outpatient benefits begin.

The Part A deductible is per benefit period, not per year
The Part A inpatient hospital deductible does not reset on a calendar-year basis. Instead, it applies per benefit period, which is a distinct unit of time tied to a hospital stay. The Part A inpatient hospital deductible covers beneficiaries' share of costs for the first 60 days of Medicare-covered inpatient hospital care in a benefit period. A new benefit period begins when a beneficiary is admitted to a hospital after having been discharged without a hospital stay for at least 60 consecutive days. This means a beneficiary who is hospitalized, discharged, and then readmitted more than 60 days later starts a new benefit period and must pay a new Part A deductible. By contrast, the Part B deductible of $240 applies on a calendar-year basis, resetting every January 1 regardless of how many times a beneficiary is hospitalized. The standard monthly premium for Medicare Part B enrollees is $174.70 for 2024. Because the Part A deductible is tied to benefit periods rather than the calendar year, a beneficiary with multiple separate hospital admissions in one year could owe the Part A deductible more than once, making the total hospital cost-sharing significantly higher than a single annual deductible would produce.

Married, living together, filing separately: the income surcharge jumps
Most Medicare beneficiaries pay the standard Part B premium of $174.70 per month, but higher-income enrollees pay an additional Income-Related Monthly Adjustment Amount (IRMAA) on top of that standard premium. The surcharge rules are especially harsh for beneficiaries who are married, lived with their spouse at any time during the taxable year, and file a separate tax return. For this filing status, the income thresholds are far lower than for other filers, resulting in a sharp surcharge jump. If modified adjusted gross income is less than or equal to $103,000, no IRMAA is added and the total monthly premium remains $174.70. However, once income exceeds $103,000 and is less than $397,000, the IRMAA surcharge rises to $384.30, bringing the total monthly premium to $559.00. For income of $397,000 or more, the surcharge reaches $419.30, making the total monthly premium $594.00. These compressed brackets mean that a married beneficiary living with a spouse who files separately can face the maximum surcharge at income levels that would trigger little or no surcharge for a single filer or a married couple filing jointly. The annual Part B deductible of $240 is the same regardless of income, so the IRMAA surcharge is the key factor that distinguishes costs for high-income enrollees in this filing category.
Premiums for high-income beneficiaries with full Part B coverage who are married and lived with their spouse at any time during the taxable year but file a separate return, are as follows: Table - Full Part B Coverage Beneficiaries who are married and lived with their spouses at any time during the year, but who file separate tax returns from their spouses with modified adjusted gross income: Income-Related Monthly Adjustment Amount Total Monthly Premium Amount Less than or equal to $103,000 $0.00 $174.70 Greater than $103,000 and less than $397,000 $384.30 $559.00 Greater than or equal to $397,000 $419.30 $594.00
