Introduction
The Centers for Medicare & Medicaid Services (CMS) and Wisconsin Physicians Service Insurance Corporation (WPS) recently notified nearly 1 million individuals that their personal information may have been compromised in a data breach. This breach involved the MOVEit software, a third-party application used to process Medicare claims and audits. As cybersecurity threats continue to evolve, this breach highlights the ongoing need for heightened vigilance and protective measures in the healthcare sector.
The Data Breach Incident
In July 2024, CMS and WPS disclosed that a security vulnerability in MOVEit, a software developed by Progress Software, had allowed unauthorized access to the personal information of Medicare beneficiaries. MOVEit was used to transfer sensitive files, including protected health information (PHI) and personally identifiable information (PII), between WPS and CMS. The vulnerability was active between May 27 and May 31, 2023, during which time hackers exploited the software to gain unauthorized access to sensitive data.
WPS initially identified the vulnerability in 2023 and applied a software patch to secure its systems. However, it wasn’t until a follow-up investigation in 2024 that they confirmed unauthorized third parties had successfully accessed some files before the patch was applied.
What Information Was Compromised
The data breach potentially exposed sensitive personal information, including:
– Full names
– Social Security Numbers (SSN) or Individual Taxpayer Identification Numbers (ITIN)
– Dates of birth
– Medicare Beneficiary Identifiers (MBI)
– Health Insurance Claim Numbers (HICN)
– Mailing addresses
– Hospital account numbers
– Dates of service
This information is critical for both identity verification and Medicare claims processing, making those affected vulnerable to identity theft and other forms of cyber fraud.
Steps Taken by CMS and WPS
Notification Process
Following the discovery of the breach, CMS and WPS initiated an extensive notification process. Letters were sent to approximately 946,801 Medicare beneficiaries whose data may have been exposed. Additionally, substitute notices were posted for individuals with outdated or insufficient contact information.
Actions Taken to Address the Breach
CMS and WPS are collaborating with law enforcement agencies and cybersecurity experts to investigate the extent of the breach and prevent further incidents. Affected individuals have been offered complimentary identity protection services, including credit monitoring, fraud resolution services, and identity theft insurance. Furthermore, CMS plans to issue new Medicare cards with updated identification numbers to those affected by the breach.
What Affected Individuals Can Do
Enroll in Identity Protection Monitoring Services
WPS is offering free credit monitoring services through Experian for a period of 12 months. This service includes identity theft protection, dark web monitoring, and fraud resolution services. Beneficiaries are urged to take advantage of these services to help mitigate the potential fallout from the breach.
Obtain a Free Credit Report
As part of the effort to protect against identity theft, individuals are encouraged to obtain a free annual credit report from one of the three major credit reporting agencies—Experian, TransUnion, or Equifax. Regularly reviewing credit reports can help detect any suspicious activity, such as accounts opened without authorization or unfamiliar inquiries.
If any suspicious activity is found, individuals should immediately report it to local law enforcement and file a police report, which will be essential for clearing fraudulent transactions.
Continue Using Medicare Card
At this time, there have been no reported cases of identity fraud directly linked to the data breach. However, CMS plans to issue new Medicare cards to affected individuals in the coming weeks. Once the new cards are received, beneficiaries should destroy their old Medicare cards and inform healthcare providers of their new Medicare numbers.
FAQs

Conclusion
The recent data breach affecting nearly 1 million Medicare beneficiaries underscores the vulnerabilities that exist in the digital age, even in sectors as critical as healthcare. CMS and WPS are working diligently to address the breach and mitigate its impact by providing support to affected individuals, enhancing cybersecurity measures, and notifying those at risk. Beneficiaries are encouraged to take advantage of the free identity protection services being offered and remain vigilant about protecting their personal information.
