HIPAA vs GDPR: Health Data Under Both Regimes

US healthcare organisations and EU/UK-facing healthtech often face both HIPAA and GDPR. They protect overlapping data types with different legal architectures — do not assume one programme covers the other.

Minimum necessary (Privacy Rule) — 45 CFR 164.502(b): Covered entities must make reasonable efforts to limit PHI to the minimum necessary to accomplish the intended purpose of the use, disclosure, or request (with listed exceptions e.g. treatment, individual access, HHS investigations).

GDPR note: Health data are a special category under Article 9; processing needs an Article 6 basis plus an Article 9 condition. Breach notification to SAs uses the Article 33 72-hour clock — different from HIPAA’s 60-day individual/HHS structure.

Frequently Asked Questions

If we comply with HIPAA, are we GDPR compliant?

No. GDPR has distinct lawful-basis, special-category, rights, and transfer rules. HIPAA compliance does not automatically satisfy GDPR.

Which breach deadline is stricter?

They measure different events. GDPR Art 33 uses a 72-hour SA clock; HIPAA uses 60-day structures for individuals/HHS under 164.400–414. Dual-scope incidents need both playbooks.

Do we need both a BAA and a DPA?

Often yes when a vendor is a HIPAA BA and a GDPR processor for the same service.
