NASCO Evolve

Automate + Clarify

Health plans have spent decades optimizing core administration systems for fee-for-service claims processing. But today’s value-based and alternative payment models operate outside those core administration systems, creating complexity, fragmentation, and limited visibility and making it increasingly difficult to manage payments consistently and transparently.

Arrangements like shared savings, quality incentives, and capitation are often the most strategically significant payments a plan makes, yet most plans still administrate them manually. Settlement takes months, there is no single source of truth for contract terms, and no easy way to understand how payments are calculated and paid. You can’t scale programs that run on institutional knowledge and spreadsheets, and you can’t defend a payment you can’t trace.

NASCO Evolve is the first system of record for administering Alternate Payment Model (APM) programs. This cloud-native, AI powered platform is designed explicitly for the complexity and variability of performance-based provider arrangements, taking plans from contract ingestion through settlement with the operational control and confidence you need.

A modern APM administration platform must do more than just analyze contracts or calculate payments. It must operationalize the entire lifecycle from contract ingestion and modeling through settlement, payment execution, governance, and auditability – at scale.

Ingest

Contract ingestion & repository

AI-assisted extraction of APM contract terms – shared savings thresholds, quality metrics, capitation rates, incentive structures – into structured, arrangement-specific schemas. Contracts are stored in a centralized repository with version history, approval workflows, and linked payment data.

Model

Contract modeling & financial controls

Models how contract terms behave financially before and during execution, including what-if scenario analysis, overlap detection, and stacking exposure identification. Built-in logic controls help prevent downstream calculation errors and reduce operational risk.

Execute

APM settlement & payment execution

Purpose-built settlement engine that calculates and executes accurate payments across shared savings, capitation, fee-for-service with quality incentives, and risk-based arrangements. Settlement outputs flow directly into payment distribution without manual reconciliation.

Analyze

Performance analytics & reporting

Provides financial visibility into provider and program performance against contract terms. Provides the portfolio intelligence teams need to identify savings opportunities, performance risks, and areas for investment optimization.

Trace

Audit trail & settlement traceability

Every payment calculation is traceable back to source contract terms and input data. Native auditability supports provider dispute resolution, regulatory compliance, and audit readiness without manual reconstruction.

Govern

System of record governance

Enterprise-grade governance with role role-based access controls, approval routing workflows, audit logging, and multi-environment management designed for high-volume, high comlexity payment administration at scale.

Scale

Sustainable program expansion

Enables APM program expansion without corresponding growth in headcount or consulting spend.
