Inpatient Hospital Deductible
10.1 - Inpatient Hospital Deductible
(Rev. 1, 09-11-02)
The patient is responsible for a deductible amount for inpatient hospital services in each benefit period. For each
year after 1991, the Secretary of the Department of Health and Human Services (DHHS) is required to set the
deductible and coinsurance amounts between September 1 and September 15 of the preceding year. The
deductible will be set at an amount equal to the deductible for the preceding year, changed by the same
percentage as applies to PPS payment rates, and adjusted to reflect changes in real case mix. The deductible and
coinsurance amounts are shown in the chart in §10.3 of this chapter.
The coinsurance amount is based on the deductible applicable for the calendar year in which the coinsurance
days occur. The deductible is satisfied only by charges for covered Part A services. Expenses for covered
services count toward the deductible on an incurred, rather than paid, basis. Expenses incurred in one benefit
period cannot be applied toward the deductible in a later benefit period. Expenses incurred in meeting the blood
deductible do not count toward the inpatient hospital deductible.
A reduction in benefit days resulting from confinement in a psychiatric hospital, on and immediately preceding
the date of entitlement, does not affect the amount of the deductible for which the patient is responsible.
If the actual charge is less than the deductible and the customary charge, the customary charge is applied to the
deductible.
A beneficiary is not responsible for payment of the deductible for an inpatient stay if the provider has been
determined to be liable because the care was not medically necessary or because the care provided was custodial.
