A. The Division of Medicaid considers a patient an inpatient if formally admitted as an inpatient
with the expectation that he/she will remain at least overnight and occupy a bed even though
it later develops that he/she can be discharged or is transferred to another hospital and does
not actually use a hospital bed overnight.
B. Inpatient services are services that are ordinarily furnished by the hospital for the care and
treatments of the beneficiary, solely during his/her stay in the hospital.
C. The three (3) day payment window rule refers to the requirement that all outpatient services
provided to a beneficiary by the admitting hospital, or by an entity wholly owned or operated
by the admitting hospital, within the three (3) days prior to an inpatient hospital admission
that are related to the reason for the inpatient hospital stay must be included in the All Patient
Refined Diagnosis Related Group (APR-DRG) payment for the inpatient stay.
