The Rodenhizer Group

With the increasingly regulated Medicaid Drug Rebate Program (MDRP), the influx of Managed Care Organizations (MCO) and the growing number of State Pharmaceutical Assistance Plans (SPAP), meeting government drug rebate requirements is a formidable challenge to every drug manufacturer.  TRG helps overcome these challenges with a highly automated approach designed to easily handle increased volume and quickly adapt to change.

Our goal at TRG is to provide our clients with a simple and efficient solution to drug rebate management.  TRG has been involved in government rebates since 2000.  Since that time we have developed a system to organize the chaos of quarterly rebate payments, established relationships with invoice providers, and evolved to meet our clients’ needs.  Manufacturers can trust in the experience of TRG to ease the process of accurate, timely rebate payments.  Allowing TRG to manage drug invoice processing can reduce the overhead costs and non-productive hours of rebate analysis and free up internal resources for other purposes.  TRG will tailor a cost-effective strategy to streamline your company’s drug rebate management.
