Definition
A laboratory billing system consumes structured activity: performed tests, modifiers, and units as agreed with finance. The LIS must emit consistent exports.
Workflow
Workflows should prevent sign-out when mandatory fields for billing are missing, where configured, and should support add-on tests with clear timestamps.
Implementation
Joint workshops with revenue cycle teams define code sets, payer rules, and exception handling for standing orders and panels.
Interoperability
Billing systems may ingest HL7 charges, flat files, or API payloads; interfaces must be tested with production-like volumes.
