Healthcare Data Breach Statistics

 

The HIPAA Journal has compiled healthcare data breach statistics from October 2009, when the Department of Health and Human Services (HHS) Office for Civil Rights (OCR) started publishing summaries of healthcare data breaches on its website.

This page is regularly updated to reflect the latest healthcare data breach statistics. These statistics and graphs were last updated on September 20, 2025, and are based on data obtained from OCR up to and including September 19, 2025.  Check back regularly to get the latest healthcare data breach statistics and healthcare data breach trends. You can view our 2024 healthcare data breach report here. You can also receive a free copy of our HIPAA Compliance Checklist to understand your organization’s responsibilities under HIPAA.

Trends In Healthcare Data Breach Statistics

Our healthcare data breach statistics clearly show there has been an upward trend in data breaches over the past 14 years, with 2021 seeing more data breaches reported than any other year since records first started being published by OCR.

Data breaches increased once again in 2022, with OCR receiving reports of 720 data breaches of 500 or more records. There was no letup in cyberattacks on healthcare organizations in 2023, which set two new records: The most reported data breaches and the most breached records. In 2023, 725 data breaches were reported to OCR, and across those breaches, more than 133 million records were exposed or impermissibly disclosed.

The healthcare data breach statistics below only include data breaches of 500 or more records that have been reported to OCR, as while HIPAA requires all data breaches to be reported regardless of size, OCR does not publish details of smaller data breaches. The breaches included in the statistics and graphs below include closed cases and breaches that are still being investigated by OCR for potential HIPAA violations.
