Upon implementation of the ADT Service, hospitals shall provide in real-time (i.e., seconds, not minutes or hours), HL7 ADT messages for all payers to the ADT Service Vendor to the extent allowed by applicable law. ADT messages should be submitted according to the HL7 ADT Specification spreadsheet.
HL7 event types for this service include admissions, discharges, and transfers from acute care and psychiatric hospitals for inpatient services and emergency department visits.
The HL7 specification includes required and expected (nice-to-have) data segments:
The specification includes required and expected fields. Ai will work with hospitals on a best effort basis to receive all TennCare-required fields, understanding this can be limited by hospital IT systems and provider workflows around capturing specific data (or the timing thereof).
Ai will work with facilities on a best effort basis to receive required fields and normalize all reported fields to meet TennCare specifications.
The HL7 ADT Specification spreadsheet includes a Data Quality tab which will be maintained for the ADT Service. It is expected that all hospitals will provide high quality, consistent and complete data. For example, at minimum, it should be possible to determine inpatient and emergency department admissions and discharges from the ADT messages. Further, other key fields such as a free-text admission reason and a codified discharge diagnosis are also expected from all sources (understanding that the codified discharge diagnosis may lag the actual discharge event by a few days).
