What Is Medical Identity Theft? Signs, Risks, and Prevention Tips

Medical identity theft is becoming a huge problem and is one of the fastest-growing types of fraud. In 2024 alone, more than 276 million healthcare records were either exposed or stolen in the U.S., according to a report from HIPAA Journal. This means that every day, hundreds of thousands of people are at risk of having their personal information misused.

The effects of stolen medical information can be much worse than credit card theft. A security breach can change your medical history, use up your health insurance benefits, and leave you with bills for treatments you never received. Sometimes, false information in your records can lead to incorrect diagnoses or blocked emergency care. The consequences can affect your finances, health, and future.

This guide will explain medical identity theft, how it happens in our connected world, and the best ways to protect yourself against it.

What Is Medical Identity Theft?

Medical identity theft happens when someone nabs your personal info, like your name or health insurance details, to get medical services or file fake insurance claims. It’s different from regular financial identity theft because it can mess up your health history and is tough to sort out.

For instance, someone could stroll into a hospital using your insurance card and get surgeries, prescriptions, or treatments that are all charged to you or your insurance. The bigger issue? Their medical info could end up in your records. If they have different blood types, allergies, or medical conditions, it could lead to major mistakes when you need care in the future.

There are all sorts of ways medical identity theft can happen. It could be someone you don’t know online or even people close to you, like family members, abusing your insurance. Criminals sometimes focus on healthcare systems, too. Victims are left dealing with financial messes and the worry that they’ll get treatment based on incorrect medical information.

How Can Medical Identity Theft Occur?

Medical identity theft can happen in several different ways. Some involve sophisticated cyberattacks, while others are as simple as someone stealing your mail. Breaking it down makes it easier to see where the risks come from.

1. Data Breaches in Healthcare Systems

Hospitals and insurance companies have a ton of sensitive information stored away. When a healthcare network gets hacked, thieves can grab a gold mine of details, like insurance info, medical histories, and personal ID numbers. These records are valuable for committing fraud, so they’re often sold online for much more than stolen credit card info.

2. Phishing and Social Engineering

Not every attack requires breaking into a system. Many criminals rely on deception. A fake email or text message that looks like it is coming from your doctor’s office or insurance company can be enough to trick someone into handing over their login credentials or personal details. Once that information is shared, it can be used instantly or stored for future fraud.

3. Physical Theft of Personal Information

Criminals can steal your medical identity in very traditional ways. They can take advantage of lost wallets, stolen mail, or even papers thrown in the trash to gather enough information to commit fraud. In some cases, healthcare employees abuse their access to patient records, making insider threats as serious as cyberattacks.

4. Fraud by Friends or Family

Sometimes medical identity theft comes from people you know. A family member might borrow your insurance card to receive treatment or prescriptions, thinking it does not harm. This “friendly fraud” can create the same problems as professional criminals, leaving you with medical bills and inaccurate records.

5. Record Errors and Mismanagement

Even simple mistakes can lead to medical identity misuse. If patient records are not correctly verified or data is entered incorrectly, someone else may be able to exploit that gap. Fraudsters can use these weaknesses to slip through the system and receive services under another person’s name.

How to Know if You’re a Victim of a Medical Malpractice?

Medical identity theft is often difficult to spot because the warning signs can feel like ordinary mistakes or billing errors. Many people only realize something is wrong once the damage has already spread.  

Unexpected Medical Bills

If you start getting bills for medical stuff you didn’t even get, that’s a huge red flag. If you’re being charged for surgeries, prescriptions, or doctor visits that aren’t yours, someone might be messing with your identity.

Errors in Your Medical Records

Medical identity theft can harm your health records by adding incorrect information. If you see allergies you don’t have, the wrong blood type, or treatments you never received in your file, another patient’s medical care may be recorded under your name.

Denial of Care or Prescriptions

Victims sometimes discover the problem when healthcare providers deny them prescriptions or medical services.. Pharmacies and hospitals may refuse treatment because their records show you already received the medication or care, even though you did not.

Collection Calls or Debt Notices

Getting calls from debt collectors about medical bills you’ve never heard of is a red flag. Fake charges can end up in collections quickly, messing up your credit score and putting a lot of unnecessary stress on you.

Strange Account Activity

Keep an eye on letters or emails from healthcare providers that mention logins, password resets, or accounts you never created. Unusual account activity can mean someone is trying to use your information online.

How to Prevent Medical Identity Theft?

Medical identity theft is easier to prevent than to fix. Once your records are compromised, repairing the damage can take years. Taking proactive steps now can lower your chances of becoming a victim and protect your health and finances.

Protect Your Personal Documents

Keep your insurance cards, medical bills, and government IDs stored securely at home. Shred old statements and never leave sensitive paperwork in the trash where it can be recovered. If you carry your insurance card, take it out only when necessary and avoid leaving it in your wallet for everyday use.

Be Selective About Sharing Information

Treat your medical and insurance details with the same caution as your banking information. Do not give your Social Security number, insurance ID, or medical history to anyone unless you are sure they are a trusted healthcare provider. If someone asks for this information, always question why it is needed and how it will be protected.

Monitor Your Medical and Insurance Records

Take some time to review your Explanation of Benefits statements, medical bills, and insurance claims occasionally. Look for any charges or services that don’t make sense to you. It’s also a good idea to occasionally ask your healthcare providers for a copy of your medical records and check for any treatments or mistakes you don’t recognize. Catching these issues early can help you avoid bigger headaches down the line.

Use Digital Security Tools

Medical identity theft often starts online, so keeping your digital life secure is super important. Always use AstrillVPN, when logging into healthcare sites or insurance accounts, especially if you’re on public Wi-Fi. A VPN helps to keep your information safe by encrypting your data, making it harder for hackers to steal your login info or personal details. Plus, using strong, unique passwords and enabling two-factor authentication boosts your security even more.

Stay Alert to Phishing Attempts

Be careful of emails, texts, or calls that look like they are from your hospital or insurance. Scammers create urgency to make people give away personal information. Always log in through the official websites instead of clicking on links. If something seems off, call your provider to check.

Place Fraud Alerts or Credit Freezes if Necessary

If you believe your information may have been exposed, consider placing a fraud alert on your credit file or freezing it altogether. This makes it harder for criminals to open new accounts or make unauthorized claims under your name.

What to Do If You’re a Victim of Medical Identity Theft?

Discovering that someone has stolen your medical identity can feel overwhelming, but taking quick and organized action is the key to minimizing the damage. Here are the steps you should follow if you suspect or confirm that you have become a victim.

1. Contact Your Healthcare Providers Immediately

The first step is to contact your doctors, hospitals, or clinics where you believe the fraudulent activity occurred. Request copies of your medical records and carefully review them for errors, such as treatments you never received or prescriptions you never filled. Ask them to flag your records and note the potential identity theft to prevent future misuse.

2. Report the Fraud to Your Health Insurance Company

Notify your health insurance provider right away. They can freeze suspicious claims, issue you a new insurance ID number, and guide you on protecting your benefits. Be sure to ask for a detailed list of all claims filed under your name, and dispute anything you did not authorize.

3. File a Report with the Federal Trade Commission (FTC)

• Go to the FTC’s official IdentityTheft.gov website and file a complaint.
  
• When you do this, you’ll get an official identity theft report. Think of it as proof you can use when dealing with hospitals, doctors, or insurance companies.
  
• The FTC will also provide a step-by-step recovery plan so you won’t have to figure things out alone.

4. Involve Law Enforcement

File a police report in your local jurisdiction. While not every case may result in immediate investigation, having an official report with insurers, healthcare providers, and credit bureaus strengthens your case.

5. Correct Errors in Your Medical Records

One of the biggest dangers of medical identity theft is incorrect information being added to your health file. These errors could impact future diagnoses or treatments. Work directly with your healthcare providers to fix these mistakes and request written confirmation once corrections are made.

6. Monitor Your Credit and Personal Information

• Request free credit reports from Equifax, Experian, and TransUnion at AnnualCreditReport.com.

• Review them and see if there are accounts or medical loans you don’t recognize.

• Set up fraud alerts or even a credit freeze if you want to be extra careful.

• Keep an eye on your medical bills, insurance statements, and explanation-of-benefit forms to spot anything odd immediately.

7. Strengthen Your Digital Security

Many cases of medical identity theft start with stolen login credentials from online health portals or insurance accounts. Use strong, unique passwords, enable multi-factor authentication where possible, and consider a trusted VPN like AstrillVPN to secure your online activity and prevent data interception.

Recent Medical Identity Theft Cases

Medical identity theft is becoming more common, and several recent cases show just how damaging it can be when health records fall into the wrong hands.

Texas Healthcare Provider Breach in 2025

In May 2025, a healthcare provider in Texas reported that hackers accessed patient medical records through a phishing attack. The attackers stole staff login details, which allowed them to get into the hospital’s electronic records system. Patients started seeing unusual insurance claims and bills they did not approve, prompting a federal investigation.

California Hospital Network Incident in 2025

Earlier in 2025, an extensive hospital network in California revealed a breach that exposed the personal and medical information of more than 150,000 patients. Cybercriminals used this data to set up fake patient accounts and file fraudulent insurance claims. The result was devastating for victims who not only had their sensitive health details stolen but also had legitimate claims denied by their insurers.

Florida Medical Billing Company Breach in 2024

In late 2024, a medical billing company in Florida experienced a serious breach that exposed Social Security numbers, insurance details, and patient treatment histories. Many victims were shocked to receive bills for procedures they never had, while others faced aggressive collection calls for debts that were not even theirs.

Conclusion

Medical identity theft is one of those issues that often goes unnoticed until it directly affects someone’s life. Unlike credit card fraud, where you might catch an unusual charge immediately, medical identity theft can hide in the background, creating long-term problems with your health records, insurance claims, and even the care you receive.

The good news is that being proactive makes a difference. Keeping a close eye on your medical bills, asking for detailed explanations of charges, and protecting your personal information are all steps that help reduce your risk. And if something ever feels off, like a bill you do not recognize or a denial for a claim you never filed, addressing it quickly can save you from bigger problems later on.
