You will not be alerted if a client revokes a Coordinated Care Consent, as that would defeat the purpose of keeping information separate. However, you will no longer be able to see information outside of your CDAG.
If the client revokes a standard Release of Information/Authorization to Disclose Confidential Information (ROI/ADCI), you can create a flag to notify other treatment team members that the client no longer allows sharing with that entity. They will only be able to see information in their CDAG, which may not include your flag or the ROI/ADCI.
