HIPAA vs GDPR: What US Companies Need to Know

Last updated: 2026-04-05 — ComplianceStack Editorial Team

Both HIPAA and GDPR protect individuals' personal information — but they take different approaches, cover different data types, and impose different obligations. US healthcare companies that serve EU patients (or accept EU clinical trial data) must comply with both.

Who Needs Both?

Key Differences Summarized

HIPAA is health-data-specific and US-only. GDPR is broader (all personal data) and extraterritorial. GDPR's breach notification window (72 hours) is much shorter than HIPAA's (60 days). GDPR requires a legal basis for every data processing activity; HIPAA allows TPO (Treatment, Payment, Operations) as a general permission.

Frequently Asked Questions

Does GDPR apply to US hospitals?

Only if they process personal data of EU residents — for example, through telehealth visits with EU patients or clinical trials involving EU subjects. Most US-only hospitals don't need GDPR compliance.

If I'm HIPAA compliant, am I GDPR compliant?

No. HIPAA compliance does not equal GDPR compliance. GDPR has stricter consent requirements, shorter breach windows (72 hours vs. 60 days), and covers all personal data, not just health data.

Which has higher penalties?

GDPR penalties can be higher for large companies (4% of global revenue). HIPAA penalties cap at ~$2.19M per violation category per year, but criminal charges are also possible.
