Document Fraud in Insurance Claims: Invoices, Receipts and Medical Records

Claims run on documents: repair invoices, purchase receipts, medical records, police reports and bills. A small share are edited or fabricated — and they are expensive, both directly and in the time adjusters spend on them. The goal isn't to slow every claim down; it's to send the right ones for a closer look.

Common document fraud in claims

• Inflated invoices — a real repair invoice with a higher total, or extra line items.
• Fabricated receipts — proof of purchase for items never owned, increasingly generated with templates or AI.
• Altered medical documents — changed dates of service, extended treatment periods, edited test values or added procedures.
• Reused documents — the same invoice or record submitted on different claims, by different claimants or to different insurers.
• Backdated documents — a policy-period problem solved by changing a date.

Quick checks for adjusters

1. Arithmetic and tax — line items, labor, parts and tax reconcile with the total.
2. Dates — service and purchase dates fit the claim timeline and the policy period.
3. Provider and merchant details — real businesses, licensed where required, contactable independently.
4. Visual consistency — edited fields often differ in font, alignment or compression from the rest of the document.
5. File origin — documents generated by billing systems look different, under the hood, from those made in editors or design apps.
6. Duplicates — fingerprints catch the same file across claims, even when renamed or slightly cropped.
7. Story fit — the documents should match the loss description, photos and police or incident reports.

Medical records need extra care

Medical documents carry privacy obligations. Check only what the claim requires — authenticity, dates and the services billed — and handle the information under the privacy rules that apply to you. When something looks altered, confirm with the provider through official channels.

Fitting automation into the workflow

Automated review scores every document as it arrives, so adjusters spend time on the suspicious few. A good setup:

• Runs on intake, before a human opens the file.
• Returns findings with their location on the page and a plain-language explanation.
• Routes high-risk documents to special investigation and lets low-risk ones flow.
• Keeps a record of every check for audit and regulatory review.

Keep a person in the loop

An automated flag is a signal, not a finding of fraud. Decisions on claims — especially denials — need human review, documented reasons and the fair-claims practices that apply in your state.

ThisVerify offers a dashboard and an API that return findings with their location on the page — a decision-support signal, with the decision staying with the adjuster.
