What this means for ad tracking

Online fax carries referrals, records and prior authorizations, so the fax service holds PHI and needs a BAA. eFax's HIPAA page lists BAA coverage for eFax Business, eFax Corporate and eFax Unite (eFax). Our guide to HIPAA compliant fax services compares which fax services sign a BAA.

Fax rarely touches your ads, but the web pages where patients request records, send referrals or book visits often carry ad pixels. A BAA binds only the vendor that signs it, and this directory lists Meta and Google Ads as not signing one, so conversions from those pages need to leave PHI behind.

Curve Compliance helps with that part: it sends the conversion itself server-side under a BAA it signs on every plan, sends each platform only a fixed list of fields, and detects PHI-like patterns before data reaches an ad platform. Book a call to see it on your own funnel.

A business associate agreement binds only the vendor that signs it, so each vendor that handles patient information for you needs its own.

How Curve helps

  • Curve carries the conversion signal to your ad platforms separately, under its own BAA, so you can keep eFax for what it does well.
  • Curve replaces browser ad pixels with one script and sends conversions server-side to Meta, Google Ads, TikTok, Microsoft Advertising and LinkedIn from Curve's servers.
  • Curve detects PHI-like patterns, such as condition names, form answers and emails in URLs, before data reaches an ad platform, and flags them so they can be stopped at the source.
  • Each platform receives only a fixed list of fields. Contact identifiers are off by default on Meta, Google Ads and TikTok, and events can use neutral names.
  • Event Logs show what Curve sent to each platform and what the platform accepted.
  • Curve signs a BAA on every plan, and Curve's team does the setup for you, typically live in about a week.
