Regulatory Compliance Requirements

Healthcare is one of the most heavily regulated industries. Non-compliance can result in massive fines, legal liability, and loss of trust.

HIPAA Compliance (United States)

The Health Insurance Portability and Accountability Act sets the standard for protecting sensitive patient data:

Key HIPAA Requirements

• Privacy Rule - Controls how Protected Health Information (PHI) can be used and disclosed
• Security Rule - Technical, administrative, and physical safeguards for electronic PHI
• Breach Notification Rule - Requirements for reporting data breaches
• Business Associate Agreements - Contracts required with third-party vendors handling PHI

Technical Safeguards Required

• Access controls and unique user identification
• Automatic logoff and encryption
• Audit controls and activity logging
• Integrity controls to prevent unauthorized alteration
• Transmission security for data in transit

International Regulations

• GDPR (Europe) - Comprehensive data protection for EU citizens, including health data
• PIPEDA (Canada) - Personal Information Protection and Electronic Documents Act
• HITECH (US) - Health Information Technology for Economic and Clinical Health Act
• MDR (Europe) - Medical Device Regulation for software as a medical device (SaMD)

FDA Regulations for Medical Software

If your app qualifies as a medical device, FDA regulations apply:

• Class I - Low risk, general controls (wellness apps)
• Class II - Moderate risk, special controls (most clinical apps)
• Class III - High risk, premarket approval (diagnostic algorithms)

Understanding whether your app is a regulated medical device is crucial early in development. Our security experts can help assess your regulatory requirements.
