Eligibility verification de-identification is the removal of all 18 HIPAA Safe Harbor IDs (45 CFR §164.514(b)) from a coverage check. anonym.plus runs on your device. The status lines stay clear, but the page no longer names the person.
When this applies
An eligibility check names the subscriber and lists the coverage tier. To reuse it for a denial study or a workflow audit, clear those IDs first.
How anonym.plus handles it
- Open the record in anonym.plus on your device.
- Local OCR reads any scanned printout too.
- The tool flags subscriber names, dates, and member numbers.
- Keep the coverage status and the benefit tier you need.
- Replace each ID with a steady alias, or redact it.
- Save the clean copy on your machine.
What you need to provide
- The record (PDF, scan, or 270/271 export).
- An operator: Replace, Redact, or Mask.
- Optional alias map for repeat subscribers.

Limitations & cautions
Group and plan codes can re-link a person to a small employer. Treat them as IDs. The tool removes the 18 types, but you still weigh whether a rare benefit tier plus a place could narrow identity.
Frequently asked questions
Is a group number an identifier?
Yes. A group or plan code can tie a person to a small employer, so it is a Safe Harbor identifier and is flagged for removal.
Does the coverage status stay?
Yes. The active or inactive status and the benefit tier stay. Only the IDs change.
Can a printed eligibility check be cleaned?
Yes. Local OCR reads scanned printouts, so the IDs are caught.
