Electronic prescribing (e-Prescribing or eRx) is not mandated in Maryland, but widely used.  Some other states and major pharmacies now require use of eRx for all prescriptions.  It is also required for eligible clinicians who meet the low volume threshold under the CMS Merit Based Incentive Payment System (MIPS).

The APA has useful resources, including an implementation toolset, on its e-Prescribing webpage.
