Medical Necessity Review Agent

Currently in beta: ensure every imaging procedure meets medical necessity criteria before it reaches a payer or becomes a denial.

proactive revenue protection

Medical necessity needs intelligence, not more labor

Medical necessity denials are expensive, slow, and avoidable.

Healthcare organizations document differently across providers and RIS or EMR systems. Payers continually update coverage criteria. And your staff spend hours reading through lengthy chart notes and payer policies, trying to determine whether a case will actually get paid.

You don’t need more people digging through records or stitching together clinical details. You need something that can understand documentation, apply the correct guidelines, and surface exactly what matters for coverage.

introducing medical necessity ai

Get instant, defensible coverage decisions

The Medical Necessity AI Agent reads clinical and payer documentation like your most experienced specialist, pulls out the clinical details that matter, and reconstructs the story beneath the noise. It knows the payer, applies the right guideline version, and connects symptoms, timelines, and prior treatments. Then it delivers a clear call: Covered or Not Covered, with clinically-accurate reasoning behind the decision.

With the support of AI providers can:

  • Stop denials before they occur
  • Speed authorizations and reimbursement
  • Catch when an ABN should be issued
  • Keep decisions consistent across teams and sites
  • Back every determination with defensible, guideline-aligned logic

Medical Necessity AI gives staff clarity, gives leadership confidence, and gives your healthcare organization or department a scalable way to take control of one of the most unpredictable steps in the revenue cycle.

How IT WoRKS

AI that understands clinical documentation and payer rules together

The Medical Necessity Review Agent mirrors the steps an expert reviewer would take to evaluate coverage criteria. It gathers the right information, interprets the clinical details, applies the correct guideline, and returns a clear determination. Here is how it works:

The agent receives clinical information by entering it directly into our system or through integration-enabled automatic retrieval. For example, CPT/HCPCS codes, diagnosis codes, and payer information would be pulled directly from the imaging order in your EHR or RIS.

It supports single or multiple CPTs, primary and secondary diagnoses, manual uploads, and automated integrations. It works seamlessly across multiple EMR systems and unstructured document formats.

Using advanced vision and language AI models, the agent extracts key findings from unstructured notes, including symptoms, treatments tried, medication relevance, imaging history, and lab results.

It reads documentation the way your most experienced reviewer would, far beyond optical character recognition (OCR) technology or keyword matching.

The agent identifies and applies the correct LCD, NCD, or commercial payer guideline based on payer type, CPT/HCPCS, ICD-10, and date of service. Guidelines are continuously monitored, versioned, and updated automatically so you always apply the correct criteria.

The agent delivers a clear, explainable determination for each case: Covered or Not Covered, with detailed rationale and references to the exact sections of the applicable policy.

When coverage is not supported, the agent identifies missing or incomplete documentation, such as conservative treatment history, duration requirements, or prior exam results. Staff can resolve these issues before submitting an authorization or claim.

Upload additional notes, corrected diagnosis codes, or missing clinical information, and the agent will instantly re-evaluate the case. There is no need to recreate or restart the process.

Coverage decision support where it matters most

Get support at critical points across the revenue cycle where accurate coverage decisions matter most. These are the workflows where you can expect the greatest impact:

Common integration patterns:

confident Prior Auth Submissions

Automatically check payer rules and eliminate back-and-forth with ordering providers.

Proactive Advance Beneficiary Notice

Identify LCD/NCD-based non-covered scenarios early to ensure accurate advance beneficiary notice (ABN) issuance.

Pre-Bill Validation

Catch medical necessity issues before the claim goes out the door, reducing denials and write-offs.

What Sets Our Approach Apart

These capabilities make our approach to medical necessity more accurate, more transparent, and easier to operationalize across your organization:

Clinical reasoning that mirrors specialist review

The Medical Necessity Review Agent serves as an expert on your payer guidelines, including what’s reimbursable and what’s not. It evaluates full clinical context, not just keywords, taking into account longitudinal histories, conservative treatment, therapy failures, medication relevance, and specialty-specific nuances. All this adds up to accurate determinations for simple and complex cases alike.

Always-current guideline intelligence

Medicare and commercial payer policies are automatically sourced, monitored, and versioned. Each case is evaluated against the correct LCD, NCD, or commercial guideline based on payer, code, and date of service.

Transparent, defensible determinations

Result includes clear rationale, criteria met or not met, and referenced guideline excerpts. This supports clean submissions, reduces preventable denials, and strengthens appeals when needed.

Flexible deployment with expert oversight

Start with manual uploads or integrate for full automation. For ambiguous or edge-case scenarios, Infinx clinical specialists provide human review to ensure consistent, reliable outcomes across specialties.

You Asked, We Answered

Medical Necessity AI will meet your needs? Here are the most common questions your peers ask during evaluation.

Currently, our AI Agent provides medical necessity coverage determinations for imaging procedures, but we are working to expand into other specialties.

Yes, with integration, all relevant demographic, clinical, and coding information can flow directly from the EMR.

A direct integration is not required. Many customers use manual entry or a work queue to pull cases from the EMR. Integration is optional and simply streamlines the workflow.

No, it’s far beyond OCR. The system uses OCR plus vision models to read images and a full AI pipeline that reads and understands payer guidelines. It then applies generative reasoning to produce human-understandable explanations.

Typically less than one minute per case.

Guideline updates are continuously monitored. The system automatically checks payer websites and versions guidelines so the correct version is applied based on date of service.

If the guideline requires labs, prior exams, conservative therapy, or clinical notes, the AI can determine whether each required document is present.

If something is missing (e.g., labs), it returns a clear “Not Covered” result and specifies exactly what requirement was missing (e.g., conservative treatment, lab results, x-rays).

Our Patient Access and RCM teams have the clinical knowledge to check for medical necessity manually in the event the AI Agent can’t return a determination. The AI is an efficiency enhancer, not a replacement or dependency for quality outcomes.
