Limitations, Dependencies, and Preconditions for Consideration Applicable Security Patterns for Consideration
  • Both the “Medication History Request” and “Medication History Response” transactions need to be implemented for interoperability purposes.
  • Both the prescriber and the specific Prescription Monitoring Drug Program (PDMP) must have their systems configured for the transaction in order to facilitate successful exchange.
  • See NCPDP projects in the Interoperability Proving Ground
  • Secure Communication – create a secure channel for client-to- serve and server-to-server communication.
  • Secure Message Router – securely route and enforce policy on inbound and outbound messages without interruption of delivery.
  • Authentication Enforcer – centralized authentication processes.
  • Authorization Enforcer – specifies access control policies.
  • Credential Tokenizer – encapsulate credentials as a security token for reuse  (e.g.,  – SAML, Kerberos).
  • Assertion Builder – define processing logic for identity, authorization and attribute statements.
  • User Role – identifies the role asserted by the individual initiating the transaction.
  • Purpose of Use - Identifies the purpose for the transaction.



NCPDP SCRIPT v10.6 was piloted by the S&I Framework and shown to effectively allow a prescriber to inquire into a PDMP using NCPDP's SCRIPT RxHistory request transaction and receive a RxHistory response. It is recommended that this standard be named so that prescriber and pharmacy system vendors can enhance systems so that these entities can obtain PDMP patient information within workflow. SCRIPT version 2017071 has recently been named in a CMS NPRM for comment and includes recommended changes as a result of the 10.6 pilots.
