Hello Team - we are looking for identifying the unique enounter business identifier for use in your application. Currently the encounter identifier we see in Encounter Resource are either account Number or Fin Number, we assume both are not unique to the encounter vs they are unique to the account. Do we have any options to get the unique enounter identifier.
Sharing below the encounter resource sample from cerner sandbox,
