Insurance Claims Document Verification API

Detect altered repair estimates, inflated medical reports, and fabricated receipts before claims are paid. A single API call surfaces forensic evidence of PDF modification — at document intake, before adjuster review.

Insurance document fraud is a $308 billion problem

According to industry estimates, insurance fraud costs US carriers $308 billion annually. An estimated 25–30% of claims now involve documents that have been digitally altered — repair estimates with inflated line items, medical reports with changed diagnoses, receipts with modified amounts.

Claims adjusters process dozens or hundreds of PDF documents per week. Manual review cannot catch structural modifications that are not visible when viewing the document. A fraudster can open a legitimate repair estimate in Adobe Acrobat, change one line item, and re-save the PDF. The resulting document looks identical to the original.

HTPBE analyzes the binary structure of each PDF for evidence of post-issuance modification. The structural traces left by editing tools cannot be removed without invalidating the document entirely.

Most common insurance document fraud patterns

  • Repair estimate: add parts that were not replaced
  • Medical report: change diagnosis code to a more expensive condition
  • Receipt: inflate labor hours or unit prices
  • Expert assessment: change the damage severity rating
  • Police report: alter the accident description or vehicle details
  • Prescription: change quantity or medication to a higher-cost equivalent

Forensic signals analyzed in every claims document

Five layers of analysis — results in under 3 seconds

Multiple xref tables

Authentic documents from repair shops, clinics, or suppliers have one cross-reference table. A second table means content was appended after the original save — the primary structural marker of claims document tampering.

Incremental update chain

Every editing session on a PDF adds an incremental update record. HTPBE counts the update chain length. A repair estimate or medical report with two or more incremental updates was processed by an editing tool after issuance.

Consumer tool producer mismatch

Legitimate repair estimates come from automotive management systems; medical reports from clinical document systems. A producer field showing “iLovePDF”, “PDF24”, or “Adobe Acrobat” indicates post-issuance editing.

Modification date after incident date

The PDF ModDate updates automatically when a file is edited. If the ModDate on a repair estimate is later than the stated repair date, or on a medical report later than the treatment date, the document was modified after issuance.

Signature bypass detection

Adjuster-countersigned claim forms are sometimes stripped of the signature page and re-submitted with altered content. HTPBE detects removed digital signature blocks at “certain” confidence — the highest verdict level.

Multi-session page assembly

Complex fraud involves assembling pages from different documents or sessions into one PDF. HTPBE’s multi-session analysis layer detects pages that originate from different rendering sessions, a strong indicator of document fabrication.

Built for claims operations teams

Integrate at document intake or use the free tool for manual spot-checks

Detect inflated repair estimates where amounts were changed before submission

Flag medical reports where the producer field reveals a consumer PDF editor, not clinical software

Catch receipts edited in Word or online tools to inflate amounts or change vendors

Identify modification dates that post-date the incident, indicating post-creation editing

Integrate into your claims management system at document intake via a single REST call

Free web tool lets claims adjusters verify suspicious documents manually without writing code

Integrate in minutes

Two calls: POST to analyze, GET to retrieve the result.

Step 1 — POST /v1/analyze

bash
curl -X POST https://api.htpbe.tech/v1/analyze \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://your-storage.com/repair-estimate-claim-4821.pdf"}'

Step 2 — GET /v1/result/{id} — edited repair estimate detected

json
{
  "id": "f7e6d5c4-b3a2-1908-7f6e-5d4c3b2a1908",
  "status": "modified",
  "modification_confidence": "high",
  "modification_markers": [
    "Multiple cross-reference tables (incremental updates)",
    "Known PDF editing tool detected"
  ],
  "producer": "iLovePDF",
  "creator": "Microsoft Word",
  "creation_date": 1711929600,
  "modification_date": 1712016000,
  "has_digital_signature": false,
  "xref_count": 2,
  "has_incremental_updates": true
}

producer: “iLovePDF” with creator: “Microsoft Word” means the document was created in Word and then processed by an online PDF editor — not generated by an automotive or medical document system. The xref_count: 2 confirms editing after the original save.

Frequently Asked Questions

Which document types in a claims package can be verified?

Any PDF document submitted as part of a claim: repair estimates, medical reports, prescriptions, invoices from service providers, receipts, adjuster reports, police reports, and expert assessments. The API analyzes the PDF binary structure, not document type — so it works on any PDF regardless of what it claims to be.

Can it detect AI-generated fake medical reports?

Partially. HTPBE detects structural modification markers — xref tables, incremental updates, producer mismatches. An AI-generated PDF created from scratch with a tool like ChatGPT or a PDF library will often return inconclusive because the file was created from scratch and never edited after creation. However, the producer and creator fields will reveal the generation tool, which is itself a risk signal for medical documents that should come from clinical systems.

What does a "modified" verdict mean for a repair estimate?

It means the PDF file contains forensic evidence of post-issuance editing: additional cross-reference tables, incremental update records, a producer field inconsistent with automotive management software, or a modification date later than the repair date. It does not automatically mean fraud — it means the document warrants manual review before payment authorization.

How does it fit into existing claims management systems?

The recommended integration point is at document intake, when the claimant or repair shop uploads PDFs to your claims portal. Send each PDF URL to POST /v1/analyze, retrieve the result from GET /v1/result/{id}, and flag any document with a modified or inconclusive verdict for adjuster review before proceeding. The API adds under 3 seconds to the processing time. Results can be stored alongside the claim record using the returned id.
