Part A to B Rebilling Guidance - JE Part A
Part A to B Rebilling Guidance
When an inpatient admission is found to be not reasonable and necessary, payment is allowed for all hospital services furnished that would have been reasonable and necessary in an outpatient setting.
Hospitals may also be paid for Part B inpatient services if it's determined that a beneficiary should have received hospital outpatient services rather than inpatient services, and the patient has already been discharged from the hospital.
NOTE: Claims that are not affected by this billing are; Recovery Audit Contractor (RAC) pre-payment review claims, Supplemental Medical Review Contractor (SMRC) post-payment review claims denied for Intensive Inpatient Rehabilitation Therapy, and pre-payment denials based on contractor review for Bariatric Surgery.
Submit a Part A provider liable claim with the below information on the UB-04 claim form.
