Since FY08, there has been a requirement for a DX code to be present for direct inpatient (INP) and outpatient (APC) visits to be workload-reportable. In the case of direct inpatient, it is specifically the PRIMARY DX code that must be present. Since, by definition, only workload-reportable visits are reported on the workload reports, visits without DX codes are edited out of the APC and INP reports. Beginning in FY12, the DX codes must indicate that some medical service was provided. For more information, please refer to the NPIRS Basic Business Rules [PDF - 557Kb].
