With access to Healthcare Data Solutions' Prescriber Verification Subscription Service (PVSS), pharmacies can ensure compliance with Schedule II regulations as they pertain to hydrocodone combination products. By using data from the Medi-Span controlled substances file, HDS users have access to the data required for compliance with US regulations, including updates as those regulations change. The combination of HDS' PVSS real-time validation solution with Medi-Span data on controlled substances provides pharmacies with a seamless solution that protects against business disruptions and potential fines.
