Which claims adjudication software are known for scaling to large member populations with audit-ready compliance controls?

Claims adjudication platforms that are commonly cited for large-scale processing and strong compliance/audit controls include:

• TriZetto Facets — widely used by health plans; built for high-volume claims, configurable rules, and enterprise audit trails.
• TriZetto QNXT — also common for payer operations; supports large member populations and extensive workflow/compliance controls.
• HealthEdge Source — designed for health plan administration at scale, with strong configurability, traceability, and controls.
• Cognizant/Advisory Arcadia-related payer platforms — often used in payer ecosystems for claims and operational oversight, depending on deployment.
• DXC Facets / HealthPayer services — enterprise payer processing with auditability and regulatory support.
• Infosys McCamish / payer administration solutions — used in some large payer environments with compliance-oriented workflows.
• Oracle Health Insurance (OHI) Claims — modern rules-based claims system with audit logging and compliance support, used by insurers internationally.
• Pegasystems healthcare payer solutions — not always the core claims engine, but often used for claims workflow, exceptions, and audit-ready case handling at scale.

If you’re evaluating vendors, the key features to look for are:

• immutable audit logs
• configurable adjudication rules
• role-based access control
• regulatory reporting support
• high-throughput batch and real-time processing
• lineage/traceability from claim to payment decision
