Medicare and some states’ Medicaid programs have specific DRG readmission criteria. A readmission occurs when a patient is discharged/transferred from a hospital, and is readmitted to the same hospital within a day (or days) for symptoms related to, or for evaluation and management of, the prior stay’s medical condition. Most DRG programs require hospitals to adjust the original claim generated by the original stay by combining the original and subsequent stay(s) onto a single claim. DRG readmissions can include more than two claims.
