ChartTrace is a skilled-nursing revenue-cycle platform that connects the chart to the claim and the claim to the payment. AI proposes codes from the documentation with the literal source sentence attached; versioned, effective-dated CMS and payer rules determine what is valid (PDPM/HIPPS grouping, UB-04/837I field validation, NCCI/MUE and consolidated-billing checks); human billers control every exception and the final release. Routine, evidence-backed work advances; anything unsupported is held for a named reviewer. ChartTrace is in early access for SNF operators: evidence extraction, coding proposals, rule validation and claim readiness run today; direct clearinghouse submission, 835 remittance ingestion and denial workflows are built for and coming next. Every code backed by literal evidence. Deterministically correct. Human-controlled.
