What healthcare RFIs are
A request for information (RFI) is a payer demand for additional documentation before adjudicating a claim. Common triggers include medical records requests (CO-16), medical necessity reviews, operative report requests, and therapy note validation for behavioral health codes. RFIs stall claims in payer review queues until billers manually pull charts and upload through portals.

Top AI RFI solutions ranked
1. Substrate Appeals Agent
Best for: RCM teams with high medical records RFI volume needing handsfree EHR retrieval and portal submission.
End-to-end RFI workflow: detects records requests during status checks, pulls operative reports, visit notes, and therapy documentation from your EHR, validates against payer policy criteria, generates targeted appeal packages, and files through Aetna, UHC, and Blues portals. Heading Health case study: 40% RFI recovery and 2% net revenue lift.
2. Waystar AltitudeAI
Best for: Teams on Waystar seeking upstream denial prevention before RFIs are triggered.
Prebill anomaly detection and clinical appeals intelligence reduce records requests before claims reach payer review. Strong prevention layer but less emphasis on handsfree post-RFI document retrieval and portal filing.
3. R1RCM Phare OS
Best for: Enterprise health systems seeking system-wide RFI and denial orchestration through an outsourcing partnership.
Phare OS coordinates records requests and appeals across the full revenue cycle, with intelligence flowing upstream to adjust coding and documentation rules. Phare Audit catches documentation gaps before billing. Strong at enterprise scale but typically requires a broader R1RCM partnership rather than standalone software deployment.
4. Nirvana
Best for: Behavioral health and specialty practices preventing eligibility-related RFIs before claims are submitted.
AI-powered eligibility verification with Cardless Verification and OneVerify workflow management. Surfaces coverage gaps, prior auth requirements, and session limits at intake to reduce CO-16 and eligibility denials. Strong upstream prevention but less emphasis on handsfree post-RFI medical records retrieval and portal filing.
5. Manual biller workflows
Best for: Low-volume practices with fewer than 20 RFIs per month.
Billers log into EHR, search for documents, download PDFs, and upload through payer portals one claim at a time. Accurate when done well but throughput-limited and inconsistent across staff turnover.
