Lumexa Imaging is a network of radiology and imaging centers. In 2026 it told the U.S. Department of Health and Human Services (HHS) that a breach had hit patient records, and the number it reported grew a lot over time. The first filing listed 2,994 people. The updated filing lists 5,830,949, which made it the largest healthcare data breach reported in the first half of 2026.
What happened
The breach did not start inside Lumexa's own network. It happened at a vendor that provided non-clinical support for the administrative work of Lumexa's affiliated radiology practices. An unauthorized person used the connection between Lumexa and that vendor to view or copy documents. The investigation placed the vendor breach between March 31 and April 9, 2026.
The vendor flagged suspicious activity on April 9, 2026. Lumexa learned on April 15 that documents containing patient information may have been viewed or taken. Lumexa reported it to HHS and notified the people affected, as the HIPAA rules require.
What was exposed
What leaked depends on the document and the person. The records included names, dates of birth and addresses. Phone numbers too. They also included patient account numbers and health insurance details. Visit dates and diagnoses were in there too. A small group of patients had their Social Security numbers exposed too.
If you had a scan at a Lumexa center, the visit date and type of scan can be as sensitive as an ID number. Together with your name and address, they tell a scammer enough to sound like your provider.
What criminals can do with it
A name and an insurance plan make a convincing call. Expect messages that claim to be from a radiology office or your insurer and ask you to confirm details or pay a balance. People answer when a message sounds like it's about their health.
Where a Social Security number and date of birth are exposed together, the risk is identity theft: loans or tax returns filed in your name. Insurance details can feed medical identity theft. That is when someone else gets care on your coverage.
Lumexa's response
Lumexa says it is unaware of any misuse of the exposed data. It is offering free credit monitoring to people whose Social Security numbers were affected. People with questions can call the number on their notice letter.
What the number means
The 5,830,949 figure is the total reported to HHS. It counts people across the practices connected to Lumexa, not only one clinic. If you have been a patient of an imaging center that partners with Lumexa, check whether a letter arrived, including in the mail you set aside.
What to do if you were in it
- 1
Read the notice letter and use the credit monitoring
If a letter says your Social Security number was involved, sign up for the free monitoring it offers before the enrollment deadline.
- 2
Freeze your credit at all three bureaus
If your Social Security number is on the notice, freeze your credit at Equifax, Experian and TransUnion. A freeze is free and takes a few minutes online. It stops new credit being opened in your name. Lift it whenever you apply for something yourself.
- 3
Expect calls and texts that mention your care
Treat any message about a scan or a bill as suspect. Hang up and call the number on your insurance card or on the practice's own website.
- 4
Read your insurance statements
Check each explanation of benefits for visits or prescriptions you don't recognize. If you find one, tell your insurer's fraud team.
