Hello Vishwa,
Thanks for the question. Patient/Practitioner relationships automatically expire after 90 days and must be re-attested by the Practitioner. If the provider wants to continue to receive data on a patient after the 90 days, they can do so by re-attributing the Patient to the Practitioner’s Group. For more information on this topic, please follow this link: https://dpc.cms.gov/docsV1#groups-attribution
