THE PROBLEM
Provider directories go stale the moment they're published.
Provider data lives across 5+ systems. Most plans publish directories that are out of date within hours.
Under No Surprises Act (NSA), CMS, and state requirements, every directory error is a fine waiting to happen. CertifyOS replaces stale, manually-cleaned directory data with continuously validated provider records — 600+ primary sources, real-time updates, full audit trail.
Five capabilities for modern directory management.

Real-time data validation
Provider directory data validated continuously against NPDB, NPPES, CAQH, state license boards, and other primary sources. No quarterly batch updates.

99.8% field-level accuracy
Field-level accuracy with configurable survivorship logic. Choose which source wins for each data element — CAQH for specialty, roster for credentials, attestation for panel status.

CMS / NSA / state-ready outputs
Directory-ready outputs formatted for CMS submissions, NSA compliance, Medicare Advantage standards, and state Medicaid Managed Care requirements.

Cross-validated against 600+ sources
Provider data cross-validated against 600+ primary sources continuously. Errors flagged before they propagate to your public directory.

Audit-ready evidence
Every directory update timestamped. Every source documented. Every change traceable to its origin. Audit-ready evidence for CMS, NSA, and state enforcement.
