Data conventions

RuleDetail
FormatAgreed per engagement. If you deliver CSV: UTF-8, comma-delimited, first row is the headers, named exactly as in the tables.
DeliveryArranged per engagement. PHI: encrypted in transit and at rest under the executed BAA.
History (USCDI feed)Date of service on or after January 1, 2016. Send active and historical records; the status columns mark which is which.
Code systemsEvery coded column has a companion _system column holding the code system URI: substance_code with substance_system, vaccine_code with vaccine_system, and so on. Leave it blank to accept the default named in that column's row.

Built on US Core

USCDI lists the data classes and the elements in each. US Core maps every element onto a FHIR element. Payerbox pins US Core 6.1.0, realizing USCDI v3 (Implementation Guides). This feed targets USCDI v3.1.
