THE 9-STAGE PIPELINE

How It Works.

A transparent, deterministic walkthrough of how clinical documentation is ingested, parsed, cross-referenced against audit rules, and delivered to human reviewers.

STAGE 01 DATA INGESTION

01. DOCUMENT

Unstructured EHR physician notes, discharge summaries, nursing assessments, operative notes, and pre-bill diagnosis/procedure code lists are ingested via standard interfaces.

STAGE 02 NLP PARSING

02. UNDERSTAND

Specialized clinical language models extract anatomical terms, symptoms, acuity indicators, surgical maneuvers, diagnostic test results, and provider MDM statements.

STAGE 03 CONTEXT RESOLUTION

03. CONTEXTUALIZE

Crucial semantic differentiation: classifies every clinical entity as active, historical, familial, uncertain rule-out, or explicitly negated.

STAGE 04 CODE CROSS-CHECK

04. COMPARE

Assigned billing codes (ICD-10-CM, CPT) are aligned against extracted clinical concepts to establish whether documentation evidence exists for every coded item.

STAGE 05 RULE EVALUATION

05. AUDIT

Deterministic audit rules evaluate clinical coding guidelines, LCD/NCD coverage policies, NCCI bundling edits, and provider organization compliance standards.

STAGE 06 EVIDENCE ANCHORING

06. EVIDENCE

For every flagged discrepancy, the engine anchors exact sentence spans in the EHR note, generating bidirectional proof links and statistical confidence metrics.

STAGE 07 RISK SCORING

07. PRIORITIZE

Encounters are placed on a multi-factor risk spectrum (Low, Moderate, High, Critical) based on evidence strength, rule severity, and potential denial impact.

STAGE 08 HUMAN OVERSIGHT

08. REVIEW

High-risk findings are queued in the human reviewer interface. Certified medical coders inspect the highlighted evidence and choose to Accept, Dismiss, or Escalate.

STAGE 09 CLAIM READINESS

09. RESOLVE

All reviewer decisions are logged in an immutable cryptographic audit record. When all blocking findings are resolved, the encounter is marked Claim Ready.
