Healthcare Claims Intelligence

Claim documents become structured evidence, then a governed decision to process, request information, or send for review.

Overview

Healthcare claims mix structured data with clinical notes, authorizations, invoices, and policy documents. This platform turns those artifacts into traceable evidence, reasons across them, and applies rules and policy before any workflow action. Understanding, decisioning, and execution stay separate. A language model does not become the authority for a consequential claim decision.

The challenge

Claims operations depend on forms, clinical notes, provider documentation, authorizations, invoices, eligibility, and benefit rules. Those sources are often separate systems.

  • Claims that need more documentation move through several manual queues.
  • Evidence sits in PDFs, scans, and clinical narrative, not only in fields.
  • Rules, policy, document evidence, and reviewer decisions are fragmented.
  • Field extraction does not by itself show how documents, clinical evidence, and policy relate.
  • A healthcare decision needs a defensible trail of what was considered and why the claim was routed.

The approach

The pipeline runs from ingestion and document intelligence through claim context, evidence retrieval, decisioning, governance, workflow, human review, and audit.

  1. 1. Document intelligence

    OCR, layout understanding, classification, entity and table extraction, terminology normalization, and relationship detection produce evidence with a source location, confidence, and time. The question is what the document proves for this claim, not only what text it contains.

  2. 2. Claim context

    Member eligibility, provider, procedure, diagnosis, date of service, billing, authorization, clinical evidence, policy, and supporting documents are normalized into one claim context for downstream services.

  3. 3. Assisted reasoning

    The model can flag incomplete evidence, cross-document inconsistency, an authorization mismatch, or a possible duplicate. It returns findings with confidence, evidence references, and a recommended next step. It does not finalize an irreversible decision.

  4. 4. Rules plus findings

    Eligibility, required data, policy, deterministic rules, and AI findings are evaluated together. The outcome is auto-process, request information, specialized review, or human decision.

  5. 5. Governance and PHI controls

    Before a recommendation changes a workflow, the platform can check model version, policy configuration, data class, confidence, claim risk, required approval, allowed actions, and PHI or PII handling.

  6. 6. Governed retrieval and workflow

    Benefit policies, procedures, and compliance documents are retrieved in a way that is contextual, permission-aware, source-grounded, and auditable. Workflow state moves from validating and evidence review through decision-ready, auto-process, request information, human review, or specialized review.

Key features

  • Traceable evidence

    Each extracted element can point back to the claim, the document, the source location, and a confidence score.

  • One claim context

    Structured claim data and document evidence are assembled once, instead of reinterpreted by every queue.

  • Findings, not verdicts

    The model reports missing information, conflicts, and recommended next actions with evidence attached.

  • Hybrid decisioning

    Deterministic policy and AI findings are both required before a claim moves.

  • Reviewer work items

    Escalated claims arrive with the summary, exceptions, rules, findings, confidence, and source documents.

  • PHI-aware governance

    Identity, data class, model version, approval, and audit sit on the path before execution.

Tech stack

The architecture can run on AWS, Microsoft Azure, or Google Cloud, using the client's existing ecosystem. High volume can process documents asynchronously so ingestion, extraction, and decisioning scale separately.

Outcomes

  • Document review

    Reduce the amount of manual reconstruction required to understand a claim's evidence.

  • Cycle consistency

    Apply policy and evidence checks more consistently, and surface missing information earlier.

  • Reviewer focus

    Send ambiguous or high-risk claims to a person with the context already assembled.

  • Traceability

    Record the path, evidence, model version, policy evaluation, decision, and any human intervention.

  • Scale

    Process higher document volume by scaling ingestion, extraction, and decision services independently.

Principles

  1. Separate understanding, decisioning, and execution.
  2. Do not let a language model make an uncontrolled production claim decision.
  3. Keep retrieval contextual, permission-aware, source-grounded, and auditable.
  4. Escalate when evidence is incomplete, rules fail, confidence is low, or policy requires a person.
  5. Build the intelligence layer around existing claims systems rather than replacing them with a chatbot.

A claim with supporting documents

A claim arrives with attachments. The platform classifies the documents, extracts fields and evidence, and builds one claim context.

  1. 1. Analyze evidence

    AI findings call out missing information, inconsistencies, and the supporting evidence that is present.

  2. 2. Evaluate policy

    Business rules and benefit requirements are applied to that context, with a risk and confidence assessment.

  3. 3. Govern the action

    The proposed next step is checked against allowed actions and PHI handling before any workflow change.

  4. 4. Process or escalate

    A low-risk, high-confidence claim can proceed when policy allows. An ambiguous or high-risk claim goes to the right reviewer with the reasoning attached. The path is audited.
