Prove Every NJ PIP Underpayment, Line by Line
PIP Engine reads a raw, unsorted packet of New Jersey no-fault medical billing PDFs and returns an audit-ready Excel showing, line by line, how much each provider is still owed under the NJ PIP fee schedule. No sorting. No data entry. Upload the packet; the reconciliation arrives by email.
From raw upload to a delivered Excel in six stages
PIP Engine processes a packet end to end without manual tagging. Each stage hands verified data to the next, and two page-accountability checkpoints reconcile page counts so a dropped page is flagged rather than silently lost.

What is PIP Engine?
PIP Engine is a HIPAA-compliant automation built for New Jersey no-fault (PIP) medical-bill review. It ingests unsorted scanned billing packets, reads every page, reconciles each billed service against the state fee schedule, and outputs an Excel workbook that documents the exact underpayment behind an arbitration demand.
PIP Engine runs unattended from end to end. An attorney or paralegal uploads a mixed set of scanned documents, and the pipeline sorts, classifies, extracts, and prices every billed line without any manual tagging. The workbook it produces is designed to be the evidentiary backbone of a no-fault arbitration demand. It is the first stage of a larger suite: its Excel output feeds a downstream brief generator that drafts the arbitration submission itself.
What problem does PIP Engine solve?
In New Jersey, auto insurance is no-fault: after a crash, your own Personal Injury Protection (PIP) coverage pays your accident-related medical bills regardless of who caused it. Insurers often underpay or deny those bills. PIP Engine proves the shortfall by reconciling every bill against the state fee schedule.
When an insurer underpays a PIP medical bill, the provider or the law firm representing them can take the dispute to New Jersey’s designated PIP dispute-resolution forum instead of filing a lawsuit. To win, they must document that the insurer paid less than the law requires. Today a paralegal does this by hand. They open scanned packets that mix many document types: medical bills (HCFA/CMS-1500 forms and UB-04 hospital bills), insurer Explanation of Benefits (EOB) statements, Assignment of Benefits (AOB) forms, ledgers, appeals, and medical records.
The packets often run to hundreds of pages, poorly scanned and out of order. For every service the reviewer reads the CPT code, the date of service, the amount billed, and the amount paid, then looks up the correct fee-schedule reimbursement and computes the shortfall. One mistyped code or wrong region lookup can sink a claim. It draws on the same disciplined extraction from scanned medical records that powers our Expert Report Engine across our regulated document work.
Why is applying the NJ fee schedule so hard by hand?
The reimbursement for a single procedure depends on several variables at once, and getting any one wrong changes the dollars owed. The New Jersey PIP medical fee schedule (N.J.A.C. 11:3-29) sets the maximum reimbursement per procedure, and that value shifts by region, provider type, procedure code, and modifier.
Every lookup combines the CPT code and its modifiers, the provider’s category (individual doctor, ambulatory surgery center, or hospital), and the region of New Jersey (North or South). That is only the base lookup. A reviewer must then apply crosswalk substitutions when a code maps to another, bilateral pricing at 1.5x for the -50 modifier, a 50 percent reduction on the second identical same-day procedure (with certain add-on codes exempt), and per-date daily caps.
When a procedure has no listed fee-schedule price, the Usual, Customary and Reasonable (UCR) benchmark applies instead. PIP Engine encodes these rules directly, so pricing is consistent across every line and every packet. It runs inside the same single-tenant isolation and signed BAA chain that protects the rest of our regulated systems.
Who is PIP Engine for?
PIP Engine is for New Jersey personal-injury and no-fault law firms and the medical providers they represent in PIP arbitration. It targets the attorneys, paralegals, and billing staff who reconcile bills against the fee schedule by hand today, and the physicians, surgery centers, and hospitals whose underpaid claims those firms pursue.
The people who feel the most relief are the ones doing the mechanical grind today. A paralegal who spends hours keying CPT codes and cross-checking EOBs against bills gets that time back. A managing attorney gets a consistent, auditable reconciliation on every file instead of output that varies by whoever prepared it. PIP Engine removes the data-entry burden while leaving professional judgment where it belongs, with the attorney.
Is PIP Engine secure and HIPAA-compliant?
Yes. All OCR and AI processing runs on HIPAA-eligible AI infrastructure under signed Business Associate Agreements. Patient health information stays inside an isolated per-firm cloud boundary with its own encryption keys, and results are delivered as short-lived download links rather than raw email attachments.
Consumer AI endpoints, which carry no BAA, are never used, and no client data trains any third-party model. The systems are engineered to meet HIPAA standards and run on AWS and Google Cloud infrastructure that holds independent SOC 2 Type II attestation and is GDPR-compliant, with single-tenant isolation, a signed BAA chain, encryption in transit and at rest, and audit trails. The pipeline never invents a fee-schedule value: any line with no fee-schedule match falls back to billed-minus-paid and is highlighted for attorney review rather than guessed.

What do you get back?
You receive an audit-ready Excel workbook, delivered by email inside a secure ZIP. The workbook carries a line-by-line billing breakdown with fee-schedule value, amount paid, and amount outstanding per service, plus a case-summary and checklist sheet. Rows the engine cannot confidently price are highlighted for review.
The ZIP also contains the original pages re-organized into one merged PDF per document type, with all HCFAs together, all EOBs together, and so on, so a reviewer can verify any number against its source in seconds. Every figure traces back to a page the arbitrator can see. To see PIP Engine against your own files, talk to the S2Reason team.
Built for one job: the NJ PIP fee schedule
PIP Engine is not generic medical billing. It encodes the region, provider-category, multiple-procedure, bilateral, daily-cap, and crosswalk rules that actually determine the dollars owed, and wraps its AI extraction in rule-based guardrails.
Whole-packet, zero-sort ingestion
Upload mixed, out-of-order scans. The engine sorts, classifies, and reconciles every page with no manual tagging or pre-organizing.
Built for the NJ fee schedule
It encodes North and South region resolution, provider-category tables, CPT crosswalks, bilateral pricing, the multiple-procedure reduction, and per-date caps.
Reads many carrier EOB layouts
It recognizes dozens of page types, including the major auto insurers' Explanation of Benefits formats, so it reads the paid amount correctly.
Total page accountability
Two enforced checkpoints reconcile every uploaded page against the delivered output, supporting evidentiary completeness in arbitration.
Deterministic guardrails around the AI
Modifiers, CPT codes, dates, and amounts are cleaned and validated by rule-based post-processors after each extraction step.
Resilient extraction
Extraction runs a primary model with automatic fallback to alternates, so a single provider outage does not fail the job.
NJ PIP reconciliation, answered
What is NJ PIP and why do these bills end up in arbitration?
New Jersey is a no-fault auto-insurance state: your own Personal Injury Protection (PIP) coverage pays your accident-related medical bills regardless of fault. Insurers often underpay or deny those bills. Providers dispute the shortfall through PIP arbitration rather than a lawsuit, and to win they must document the exact underpayment against the state fee schedule.
What does PIP Engine actually do?
PIP Engine converts a firm's raw, unsorted PDF packet of bills, EOBs, and forms into an audit-ready Excel showing how much each provider is still owed. It reads every page with no manual data entry, classifies and separates the documents, extracts each billed line item, and applies the NJ PIP fee schedule to compute the shortfall.
Does a human still need to review the output?
Yes, by design. The engine flags anything it cannot confidently price, and any AI-assisted legal content is explicitly marked as needing attorney review. PIP Engine removes the mechanical grind of reconciliation, not the professional judgment that belongs to the attorney.
How does it handle EOBs from different insurance carriers?
PIP Engine recognizes dozens of distinct page types, including the major auto insurers' Explanation of Benefits layouts, so it reads the paid amount correctly across carriers. It then matches each paid line back to the original bill by date of service and procedure code, which is the step manual reviewers most often get wrong.
Why is applying the NJ fee schedule so hard to do by hand?
Because the reimbursement for one procedure depends on the CPT code, its modifiers, the provider category, and the region of New Jersey, all at once. On top of that base lookup, a reviewer applies crosswalk substitutions, bilateral pricing at 1.5x for the -50 modifier, a 50 percent reduction on the second identical same-day procedure with add-on exemptions, and per-day caps. Only then can they subtract what the insurer paid. One wrong variable changes the dollars owed.
Is patient health information kept secure and HIPAA-compliant?
Yes. All OCR and AI processing runs on HIPAA-eligible AI infrastructure under signed Business Associate Agreements. Data stays inside an isolated per-firm cloud boundary with its own encryption keys, and results are delivered through secure, short-lived download links rather than raw attachments.
