Level 1 System Capabilities

Systems with Level 1 capabilities provide the minimum requirements for systems to participate in the exchange of an electronic referral request.

L1: Send, Receive, Revoke

To support the electronic exchange of referral information from a system the basic requirements are below.¹

A Source System claiming compliance with Level 1 SHALL have the ability to generate and transmit a valid message to a Target System when:

• A new Service Request is created, assigned to a Performer HCP (or Case Assigner) and submitted
• A message to Revoke the Service Request when it has been incorrectly assigned or submitted in error

A Target System claiming compliance with Level 1 SHALL have the ability to receive and appropriately process a valid message received from a Source System when:

• A new Service Request is created, assigned to a Performer HCP (or Case Assigner) and submitted
• A message to Revoke the Service Request when it has been incorrectly assigned or submitted in error

Note: ¹ Without the ability to participate in the bi-directional exchange of information a system is insufficient for closed loop eReferral or eConsult.

State Machine

In Level 1 integrations, the focus of messages is always on the service request. The exchange of information is triggered as the Requester HCP (or delegate) performs actions that change its state.

Noting that the Requester HCP is driving the states of this diagram and determine referral completion.
