## OperationDefinition: Unalignment Request

Official URL: https://globalalliantinc.com/access/OperationDefinition/Unalign | Version: 0.9.0
Active as of 2026-03-06 | Computable Name: Unalign

The $unalign operation supports the ability to manually unalign a patient from the participant in a specific ACCESS track. There are a specific set of reasons a patient can be unaligned such as the patient has moved outside of the care radius of the participant or despite good faith efforts, communication with the patient has ceased. When unalignment is successful, the system automatically sends notifications to the participant confirming the unalignment, then all FHIR subscriptions created during the original alignment are cancelled to prevent future erroneous notifications.
