What it detects
What FileSentinel finds
FileSentinel flags medical record numbers, patient identifiers, and insurance member numbers, scoring each by the surrounding clinical and personal context. That context is what separates a true MRN from an ordinary reference number.
Where it hides
- Spreadsheets and CSV exports
- Word and PDF documents
- Scanned forms (via OCR)
- Text and email exports
Why it matters
The risk of leaked MRNs
Medical record numbers tie directly back to a patient, making them PHI under HIPAA. They spread through scheduling exports, referral letters, and billing spreadsheets.
- Scheduling and EHR exports
- Referral and discharge letters
- Billing and claims spreadsheets
- Scanned forms and faxes
How FileSentinel handles it
Built-in detection, scored and local
FileSentinel reads inside your files on your own machine, flags MRNs with a confidence and severity score, and helps you remediate. Built-in detectors cover the common cases, and a custom rule builder lets you add plain-text or regex detectors for anything specific to your work.
Every finding gets a confidence and severity score, so real MRNs rise above coincidental matches.
With OCR on, FileSentinel reads text inside images and scanned PDFs, catching MRNs in screenshots and scans.
Redact values, mark false positives, or export a CSV, HTML, or PDF report, then share with confidence.
Private by design
Your files never leave your PC
Scanning, OCR, and remediation all happen on-device. FileSentinel makes no network connections to do its work, so the very data you are trying to protect never has to leave your machine to be checked. No server, no cloud, no upload step.

Find MRNs FAQ
How do I find medical record numbers (mrns) in my files on Windows?
Install FileSentinel from the Microsoft Store, point it at a folder or drive, and start a scan. FileSentinel reads inside your files, flags medical record numbers (mrns), and scores each finding by confidence and severity so the real risks rise to the top.
Is scanning for medical record numbers (mrns) private?
Yes. FileSentinel runs entirely on your device. Scanning, OCR, and remediation all happen locally with no uploads and no cloud, so the data you are trying to protect never has to leave to be checked.
Can FileSentinel tell an MRN from any reference number?
It scores each candidate against nearby clinical and personal context, so a number that travels with a patient name or health detail ranks above a generic invoice or ticket number.
What file types does FileSentinel check for medical record numbers (mrns)?
FileSentinel reads inside documents, spreadsheets, text, and PDFs, and with OCR enabled it reads text inside images and scanned PDFs too, so medical record numbers (mrns) captured in a screenshot or scan is caught as well.
