GP practices and primary care 

CSAS offer general support/instructions to GPs and Primary Care organisations for submitting a Cease, Defer or Reinstate request.

Submit a Cease or Defer request 

Via the Prior Notification List (PNL) via OpenExeter 

To avoid unwanted invitations being sent, GP practices should submit Cease and Deferral notifications to CSAS via their PNL.  

If the patient is not due on a PNL, practices should submit the relevant cease or defer form.
