Outpatient Claims Grouper
For inpatient services, the MS-DRG system gives hospitals a fairly simple mechanism for grouping patients into meaningful service lines and sub-service lines. However, no MS-DRG-like system exists for outpatient services. Advisory Board has developed a proprietary methodology to help hospital members group and organize their outpatient services. This methodology can be readily integrated into existing hospital information systems.
