What Is HL7 v2 PV1-9? Consulting Doctor, Explained for Testers
A patient can easily have three or four consulting physicians on a single complex inpatient stay, and PV1-9 is built to carry all of them — but plenty of care-team displays were coded against single-doctor test data and simply show the first name repeated in the field.
PV1-9 is the ninth field of the PV1 segment — a repeatable composite (XCN data type) listing one or more consulting physicians involved in the visit, separated by a ~.
What this field contains
Example
The 9th field (889900^LEE^DAVID^R^^MD) lists Dr. David R. Lee as a single consulting physician; a multi-consult stay would repeat this with a ~. Synthetic patient — not a real person.
Where this trips people up
Because most test messages only ever include one consulting doctor, care-team widgets and clinical dashboards are frequently built to read just the first repetition of PV1-9 and never parse the ~-delimited repeats. On a real multi-specialty inpatient stay, that means cardiology, nephrology, and infectious disease consults can all be sent correctly in the message and still only the first one ever appears on screen.
