The ACCESS Model provides automatic email notifications for important events during the patient ACCESS Model lifecycle.
Upon successful patient alignment, participants are automatically enrolled to receive email notifications about upcoming deadlines and events that require action or awareness. These email notifications are automatically stopped when a patient is unaligned, either manually or through the ACCESS Model system.
The following event types trigger email notifications to ACCESS participants:
| Event Name | Event Code | Description | When Triggered |

| Provider Lock-In Period Ending | provider-lock-ending |
The 90-day provider lock-in period is ending soon, allowing the patient to switch to a different provider if desired | Before the lock-in period ends |
| Control Group Period Ending | control-group-ending |
The 12-month control group assignment period is ending soon, allowing the patient to be reconsidered for alignment in the ACCESS Model | Before control group period ends |
| Alignment Renewal Due | alignment-renewal |
The initial alignment period is ending and renewal action is required to continue services under the ACCESS Model | Before initial alignment period expires |
