Change Healthcare, a major healthcare technology company, experienced a significant ransomware attack on February 21, 2024. This incident led to the exposure of personal data for an estimated 190 million individuals. The Minnesota Attorney General's office is actively investigating this breach.

If you received a notification letter from Change Healthcare, it confirms that your personal information was affected. The specific data categories reported as exposed include Social Security numbers, medical records, insurance information, and billing records. The letter should detail exactly which of your data types were compromised.

The exposure of such sensitive data carries risks, including potential identity theft or fraud. Malicious actors could attempt to use Social Security numbers to open new accounts or misuse medical and insurance information. It is important to review your notification letter carefully to understand the scope of the exposure.

Upon receiving a data breach notification, consider immediate actions like monitoring your credit reports and reviewing explanation of benefits (EOB) statements from your insurer for any unusual activity. If offered, enroll in any free credit monitoring or identity protection services provided by Change Healthcare. This can help detect fraudulent use of your information early.

While an active investigation is underway, understanding your legal options is also important. The notification letter is a critical document in this process. Keeping a copy and noting the date you received it can be useful.

For those affected by the Change Healthcare data breach, reviewing your situation with legal counsel can clarify your rights and potential next steps. We offer a free, no-obligation case review to help you understand what this breach means for you.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Check for medical identity theft

    Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.

Change Healthcare data breach notice and letter questions

Is the Change Healthcare data breach letter legit or a scam?
A notice from Change Healthcare in the mail matches the breach Change Healthcare reported to the MN Attorney General on January 8, 2026, which covers about 190,000,000 people. Check that the company name and dates in your letter match that filing.

Change Healthcare reported that about 190,000,000 people were affected and lists the following information as involved: Social Security numbers, medical records, insurance information, billing records.

Did Change Healthcare offer free credit monitoring?
Look for an enrollment code in your Change Healthcare notice. Companies that offer free credit monitoring after a breach usually include it there, with a deadline to activate. Because Social Security numbers are listed in this filing, identity monitoring and a credit freeze matter more than usual. Signing up doesn't waive any legal rights you may have.

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.
Is there a Change Healthcare 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. This page doesn't confirm that a lawsuit has been filed against Change Healthcare.

Do I need a Change Healthcare data breach lawyer or attorney?
Talking to a data breach attorney costs nothing here. A lawyer can read your notice, explain your rights under your state's law and tell you whether a claim makes sense.
How much could a Change Healthcare data breach settlement or claim be worth?
There is no set amount, and no Change Healthcare settlement is confirmed here. In past data breach settlements, payments depended on what data was exposed and on documented losses — fraud, out-of-pocket costs and time spent dealing with the breach. The filing lists Social Security numbers, medical records, insurance information as involved. Keep receipts and records; they're what damages claims are built on.
Can I sue Change Healthcare over the data breach?
It depends on what was exposed, the law in MN and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.
