The Diagnosis Related Group (DRG) is the primary component of health care claims reimbursement determination for Medicare and other payers. DRG specifications are produced and maintained by the Centers For Medicare and Medicaid Services (CMS), a division of the U.S. Dept of Health and Human Services. Patient information including age, sex, and discharge status along with detail diagnosis and procedure code data from the patient record are processed through a complex algorithm to calculate the DRG. Associated with each DRG are weighting factors and statistical averages for the length of stay in an inpatient hospital. These data, when combined with hospital-specific cost factors are used to compute Medicare reimbursement for a hospital stay.

Software developers and system integrators! DRGActive DRG DLLs are the easiest way to add complex DRG calculation logic to your systems or applications. By simply referencing the DRGActive™ DRG DLL within your application, setting the input property values, and executing the DRGCalc method you can calculate the DRG and retrieve the DRG Weight, Average Length of Stay and other important DRG data elements. The data returned from DRGActive™ is compliant with CMS DRG specifications. These components allow you to add DRG functionality to your systems and applications built for the Windows client environment.
