Remittance advice redaction is the removal of the 18 HIPAA Safe Harbor IDs (45 CFR §164.514(b)) from a provider payment notice. anonym.plus runs on your device. The payment lines stay clear, but the page no longer names the patient.
When this applies
A remittance notice lists each patient, the adjustment codes, and the amounts paid. To study denials or train billers, clear the IDs first.
How anonym.plus handles it
- Open the notice in anonym.plus on your device.
- Local OCR reads the printed grid, even on a scan.
- The tool flags patient names and member numbers.
- Keep the adjustment codes and the paid amounts.
- Replace each ID with a steady alias, or redact it.
- Save the clean notice on your machine.
What you need to provide
- The notice (PDF, scan, or 835 export).
- An operator: Replace, Redact, or Mask.
- Optional alias map for repeat patients.

Limitations & cautions
A remittance grid can list many patients per page. Check that every row is scanned, since one missed name still exposes a person. The adjustment codes stay and are not treated as identifiers.
Frequently asked questions
Do the payment lines survive redaction?
Yes. The adjustment codes and the paid amounts stay. Only patient IDs change, so the page is still useful for review.
Are provider details removed?
Provider names are not patient PHI. They can stay via an allow-list, or be swapped for a blinded study.
Can a scanned remittance be cleaned?
Yes. Local OCR reads scanned pages, so IDs in image files are caught.
