Catalyst Physician Group data breach questions
- How many people were affected by the Catalyst Physician Group data breach, and what was exposed?
- The filing does not give a count of affected people and lists the following information as involved: Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, Provider and Treatment Dates. Your own letter is the best guide to what was exposed about you, since notices are usually tailored to each person.
- Is the Catalyst Physician Group data breach letter legit or a scam?
- A notice from Catalyst Physician Group in the mail matches the breach Catalyst Physician Group reported to the Texas Attorney General on September 15, 2026. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact Catalyst Physician Group through a phone number or website you find yourself.
- Did Catalyst Physician Group offer free credit monitoring?
- Any free monitoring Catalyst Physician Group is offering will be described in the notice you received, along with an activation code and a sign-up deadline. Because Social Security numbers are listed in this filing, identity monitoring and a credit freeze matter more than usual. Enrolling does not give up your right to bring a claim.
- Is there a Catalyst Physician Group data breach class action lawsuit?
- Law firms often open an investigation after a breach notice like this one, and a class action lawsuit may follow.

You usually don't have to join a class action to be included — if a settlement is reached, class members are notified and can file a claim.
- What should I do after getting the Catalyst Physician Group data breach notice?
- Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.

- How much could a Catalyst Physician Group data breach settlement or claim be worth?
