About The Change HealthCare Data Breach

On February 21, 2024, a cybercriminal group known as Blackcat broke into Change Healthcare’s systems and stole sensitive personal data, including:  

  • Social Security numbers
  • Medical and insurance records

The hackers demanded a $22 million ransom, according to NPR. The attack led Change Healthcare to shut down systems used by doctors, hospitals, pharmacies, and insurers.  

Understanding Change HealthCare Cyberattacks Impact

The Change Healthcare data breach is the “most serious incident of its kind leveled against a U.S. healthcare organization.

Change Healthcare, a division of UnitedHealth Group, is the largest healthcare payment processor in North America, handling about 15 billion transactions each year and one in three patient records. The attack affected patients, hospital systems, physicians, clinical social workers, and private and government-owned pharmacies.  

Medical providers said they were:  

  • Unable to pay employees or bills  
  • Unable to check patient eligibility for treatment or verify insurance coverage 
  • Unable to receive reimbursement for services provided  
  • Facing major cash flow issues and revenue loss  

A March 15, 2024 survey by the American Hospital Association found that  94% of hospitals experienced financial impact following the attack, with 60% losing $1 million or more per day.

It’s been one of the most stressful things we’ve gone through as a practice, and that’s saying something given that we survived COVID […] To find ourselves suddenly, you know, looking at our home and its value, and can we afford to put it up to pay our employees, is a terrible feeling.

Dr. Purvi Parikh, an allergist and immunologist in New York City, told CNBC that her practice hadn’t been able to receive reimbursement from insurers for patient visits, which  made it difficult to pay for operational expenses, calling the situation a “mess,” and “big stressor.”
