CMS: Do I have to contact ePharmacy helpdesk to get details of patients who are registered for CMS but have no PCR?

No.

This is one of the new functionalities in PCR Version 11 (March 2016).

You are now able to see core service registration information from PRS (Patient Registration Service). This includes MAS registration status as well, although this is updated weekly where CMS data is updated daily.

For further information, please refer to the "What's New?" PCR version 11 quick reference guide.
