EOB redaction is the removal of the 18 HIPAA Safe Harbor IDs (45 CFR §164.514(b)) from a benefits statement. anonym.plus runs on your device. The cost lines stay clear, but the page no longer names the person.
When this applies
A benefits statement lists the patient, the subscriber, and the amounts paid. To use it in a dispute file or a teaching set, clear those IDs first.
How anonym.plus handles it
- Open the statement in anonym.plus on your workstation.
- Local OCR reads the printed grid, even on a scan.
- The tool flags the patient, the subscriber, and ID numbers.
- Confirm the flags and keep the charge and payment columns.
- Replace each ID with a steady alias, or redact it.
- Save the clean page. Nothing is sent off the device.
What you need to provide
- The statement (PDF, scan, or payer export).
- An operator: Replace for readable copies, Redact for audit trails.
- Optional alias map to keep one person steady across pages.

Limitations & cautions
Safe Harbor also needs you to have no reason to think the rest could re-identify the person. The tool removes the 18 ID types. You still judge rare free-text clues. For those, use Expert Determination instead.
Frequently asked questions
What is a Safe Harbor identifier on an EOB?
Names, the address, all dates tied to the person, the member or subscriber number, the account number, and the reference code. The tool flags each as a Safe Harbor item.
Will the cost breakdown survive redaction?
Yes. The charge, allowed, and paid amounts stay. Only the IDs change, so the page is still useful for review.
Can a scanned statement be cleaned?
Yes. Local OCR reads scanned pages, so IDs in image files are caught.
