Per case reimbursed admissions only

All inpatient days that are reimbursed under a diagnosis-related group (DRG) and/or per-case payment rate are subject to Medical Necessity review, which may include concurrent review and/or retrospective review. Admissions that have been preapproved will not be retrospectively denied for Medical Necessity unless the Preapproval was based on erroneous information or misinformation provided by the hospital. 

Readmissions 

Readmissions are subject to the Inpatient Hospital Readmission policy, which applies to hospitals and health systems paid per case or per admission for inpatient hospital stays. For additional information on readmissions, please refer to our medical policies at www.ibx.com/medpolicy. 

Ungroupable or invalid DRG 

Claims that are ungroupable or group to an invalid DRG will be denied payment. Claims may be resubmitted by the hospital with corrected data.

Version DRG versus rate effective date 

Unless otherwise specified in the contract, the grouper version used will be based on the contracted version in effect on the date of admission. For all hospitals, the CMS Pricer adjustment factor applied to the DRG pricing will be based on the date of admission. 

Per-diem reimbursed admissions only 

All inpatient days that are reimbursed under a per diem payment rate are subject to a concurrent review of Medical Necessity. In the event the hospital fails to provide timely medical information necessary for concurrent review as requested by IBC, inpatient days not reviewed concurrently will be reviewed retrospectively for Medical Necessity. Admissions that have been concurrently reviewed will not be retrospectively denied for Medical Necessity unless the concurrent review was based on erroneous information or misinformation provided by the hospital.
