Capitation report anonymization is the removal of the 18 HIPAA Safe Harbor IDs (45 CFR §164.514(b)) from a per-head payment roster. anonym.plus runs on your device. The payment math stays clear, but the report no longer names anyone.
When this applies
A capitation roster lists each enrollee and the monthly amount paid to a group. To study payment trends or train staff, clear those IDs first.
How anonym.plus handles it
- Open the file in anonym.plus on your device.
- It scans the member column and the contact fields.
- Names and member numbers get flagged per row.
- Keep the per-head amounts and the rate band.
- Replace each ID with a steady alias, or redact it.
- Save the clean report on your machine.
What you need to provide
- The roster (CSV, PDF, or payer export).
- A column map for the member ID fields.
- An operator: Replace, Redact, or Mask.

Limitations & cautions
A roster can list thousands of rows. Check that the member column is mapped so no name slips past. The per-head amounts stay and are not treated as identifiers, though a tiny rate band tied to a region can add to risk.
Frequently asked questions
Does the payment math survive the swap?
Yes. The per-head amounts and the rate band stay, so the roster is still useful for trend study.
Are enrollee numbers identifiers?
Yes. A member or enrollee number ties a row to one person, so it is a Safe Harbor identifier and is flagged.
Can a large roster be cleaned in one run?
Yes. Point anonym.plus at the file and it works through each row on your device.
