AUTONOMOUS MEDICAL BILLING SENTINEL • AWS STRANDS & BEDROCK

The Sentinel that
excises the Unbundled

Hospital revenue-cycle software automatically injects billions in duplicate CPT codes. UNBUNDLE is the autonomous counter-battery—auditing EOB claims against federal CMS NCCI rules in 0.3 seconds.

01 // DETERMINISTIC AUDIT MATRIX

Four Mathematical Truth Gates.
Zero Probabilistic Hallucinations.

Hospital revenue-cycle software relies on patient exhaustion. UNBUNDLE deploys four deterministic legal and cryptographic gates where LLMs are physically barred from touching claim dollar amounts.

CMS NCCI ENGINE

Surgical Procedure Code Decoupling

SQLite-backed Procedure-to-Procedure (PTP) validator intercepts mutually inclusive unbundled line items in 0.3 seconds.

SILENCE LEDGER

Silent Background Auditing

Routine wellness exams and clean claims are checked against CMS NCCI tables and archived. No notifications. No alert fatigue.

AWS CEDAR GATE Cedar Padlock

Physical Policy Hard-Lock

The agent is physically forbidden by compiled Cedar policy from dispatching legal appeals or signing documents without the patient's explicit key.

ERISA § 503 REGULATORY CLOCK

Post-Dispatch Federal Clock

Under 29 CFR § 2560.503-1, payors have exactly 30 calendar days to adjudicate. If they stall, remedies are deemed exhausted by operation of law.

02 // ARCHITECTURAL TOPOLOGY

From S3 Event to Certified Dispute:
The 5-Node Circuit

Every stage in the UNBUNDLE pipeline adheres to an immutable verb pipeline: a hard cryptographic separation between cognitive observation and physical execution authority.

UNBUNDLE 3D Circuit Architecture
01 / INGEST (EOB)

Headless Event Ingestion

Amazon Bedrock AgentCore daemon intercepts incoming EOBs via S3 ObjectCreated events or email wire monitors.

02 / AUDIT (CMS NCCI PTP)

Deterministic Database Crosswalk

Local SQLite tables query Column 1/Column 2 edits. Zero LLM hallucinations touching clinical codes.

03 / NET (0-BLOCK DELTA)

Continuous Net Settlement

Deduplicates collisions across line items, preventing double-counting and recalculating lawful patient liability.

04 / ATTENUATE (AWS CEDAR)

Least-Privilege Policy Guardrail

Cedar asserts that `context.human_approval_token_valid == true` before any external dispute can be dispatched.

05 / 1-TAP APPEAL

Certified ERISA Legal Dossier

Patient signs with 1 tap. Cedar unseals. Statutory dispute packet citing 29 U.S.C. § 1133 is emitted.

04 // RADICAL HONESTY

The Bug Story:
What Broke on Real Payor Data.

Deltr tested against real Binance order books with real latency. UNBUNDLE tested against messy real-world hospital EOB exports. Here is where the LLM failed, and how we bound it.

What Generic AI Does (The Slop)

When an EOB writes MISC SURGICAL SUPPLIES TRAY 3 or GLOBAL FACILITY OVERHEAD without a 5-digit CPT code, generic LLMs guess random codes and invent hallucinated dispute arguments.

How UNBUNDLE Binds It (The Quarantine)

UNBUNDLE implements a mathematical Clinical Confidence Gate. Descriptions with confidence < 0.90 are automatically quarantined. They are physically barred from the SQLite NCCI tables, preventing false-positive legal claims.

REAL OCR TEST LOG // tests/fixtures/real_unstructured_eob.txt
Line 05: 'MISC SURGICAL SUPPLIES TRAY 3' → Confidence 0.25 < 0.90 → QUARANTINED (Refused to Hallucinate CPT)
Line 06: 'GLOBAL FACILITY OVERHEAD CHG' → Confidence 0.25 < 0.90 → QUARANTINED (Requires Itemized Operating Room Log)
05 // THE AUTONOMOUS COUNTER-BATTERY

Real-Time Interception Matrix:
Targeting Unbundled Codes Before Settlement.

Hospital revenue-cycle engines generate millions in phantom claims by unbundling panel codes. UNBUNDLE operates as an autonomous electronic counter-battery—intercepting illegal CPT splits in 0.3 seconds before patient liability registers.
