Beginning October 1, 2016, practitioners must be registered with the PDMP prior to obtaining a new or renewal Maryland State Controlled Dangerous Substances (CDS) Registration (issued by the Office of Controlled Substances Administration – formerly the Division of Drug Control.)  Click here for more details.  Beginning July 1, 2018 PDMP use by CDS prescribers will be mandatory.

MedChi has prepared a useful timeline of PDMP registration, as well as PDMP query requirements for prescribing opioids and benzodiazepines.
