MyChart Privacy Policy

Epic Systems | Last reviewed: January 2026

Privacy Summary

MyChart is governed by HIPAA, but that doesn't prevent extensive data sharing within Epic's Care Everywhere network. Your records may be accessed by any health system in the Epic network for treatment purposes, and de-identified data feeds research and analytics. The scale of Epic's network makes this one of the largest health data sharing arrangements in existence.

Data Collection Overview

Data Type Collected Shared Sold
Medical Records Yes (complete) Epic Network No (HIPAA protected)
Diagnoses & Conditions Yes Care Everywhere De-identified to research
Prescription History Yes Pharmacies, Insurers De-identified to pharma
Lab Results Yes Treating Providers De-identified to research
Portal Usage Yes Health System Analytics No

Key Privacy Concerns

Care Everywhere Network Scale

Epic's Care Everywhere connects over 250 million patient records across thousands of health systems. Your data can be accessed by any provider in this network, creating one of the largest de facto health information exchanges.

De-identification Limitations

HIPAA's de-identification standard allows significant data sharing for research. Medical records are notoriously difficult to truly anonymize—conditions, demographics, and treatment patterns can identify individuals.

Research Data Flows

Health systems regularly contribute de-identified MyChart data to research databases, clinical studies, and Epic's own research initiatives. Consent is typically buried in health system terms.

Third-Party App Connections

MyChart allows connections to third-party health apps via Apple Health and other integrations. Once data leaves MyChart, it may no longer have HIPAA protection.

Positive Aspects

HIPAA Baseline Protection

Unlike consumer health apps, MyChart data is protected by HIPAA, which restricts certain commercial uses and requires security safeguards.

Patient Access Rights

HIPAA gives you strong rights to access and download your own records. MyChart generally makes this easier than paper-based systems.
