Quick answer:
The best AI solutions for payer policy review ingest medical necessity policies and LCD/NCD documents, match encounters to clinical scenarios, evaluate documentation against each criterion, and feed results into targeted appeals or pre-submission fixes. Substrate Policy Review Agent leads for behavioral health and orthopedics across Aetna, UHC, BCBS, and Cigna. Waystar focuses on prebill anomaly detection. Manual policy review by billers does not scale.
Inclusion criteria:
Vendors that automate claim status, denials, or AR follow-up with published payer coverage or a live customer footprint. Ranked for in-house hospital, health system, and physician-group RCM teams.
Honest limitations: Substrate does not replace a clearinghouse, EHR, or full-cycle BPO. It automates post-submission AR (status, appeals, posting, eligibility) and still routes clinical edge cases to staff. Coding, CDI, and patient-facing billing are out of scope.
Why policy review matters for denial prevention
Medical necessity denials require proving specific payer criteria are satisfied in the clinical record. Generic appeals that do not reference payer policy rules have lower overturn rates than targeted, evidence-based packages.
Top AI policy review solutions
1. Substrate Policy Review Agent
Best for: Specialties with high medical necessity denial rates needing pre and post-denial policy evaluation.
Ingests payer policies into structured criteria, matches encounters to clinical scenarios, evaluates records against each rule with met/not met results, and feeds outcomes into the Appeals Agent or pre-submission documentation fixes.
2. Waystar AltitudeAI
Best for: Teams on Waystar seeking upstream denial prevention through prebill anomaly detection.
Identifies coding and documentation gaps before submission. Strong prevention layer but less emphasis on post-denial criteria-level appeal building.
3. Manual policy review
Best for: Low-volume practices with fewer than 10 medical necessity denials per month.
Billers read dense payer PDFs and manually map documentation to criteria. Accurate when done well but throughput-limited and inconsistent across staff.

Frequently asked questions
What types of policies does the agent support?
Medical necessity policies, LCD/NCD documents, and coverage determinations from Aetna, UHC, BCBS, Cigna, and regional plans.
Can it validate documentation before a procedure?
Yes. Run evaluation pre-procedure to confirm documentation meets criteria while there is still time to adjust before claim submission.
How does this connect to appeals?
The structured evaluation feeds directly into the Appeals Agent as the foundation for targeted, evidence-based appeal packages.
