The phone is ringing. Do you answer it? It might be an old friend you’d enjoy catching up with. On the other hand, it might be the latest scam artist.
Whatever the case, everyone — particularly older individuals — tend to be on guard when answering calls from unknown numbers. If you’re caught unaware, you could find yourself sharing personal information and putting yourself at risk.
When it comes to your personal information, always be on guard. Share only what is absolutely necessary.
Erin Reese, cyber security incident response manager, Wellmark Blue Cross and Blue Shield
According to the American Journal of Public Health External Site, 1 in 18 older Americans fall victim to financial fraud or scams annually. That figure excludes those who have been financially abused by friends and relatives. Overall, it’s estimated that 5.4 percent of older adults experience some form of fraud or scam each year.
In the case of medical identity theft, your personal information can be used to falsify insurance claims and get Medicare benefits.
"Your personal information is incredibly valuable," says Erin Reese, cyber security incident response manager at Wellmark Blue Cross and Blue Shield. "In the wrong hands, it can be used to steal medical services, prescriptions, surgeries and more. This can wreak havoc on your life and your finances."
Wellmark will not contact you via phone or email to collect your personal information such as social security numbers, though you may receive mailed letters requesting personal information.
If you are unsure, you can tell the caller you will call back, then call the number on the back of your ID card to ensure you reach Wellmark Customer Service.
Five ways you can help protect your medical information
Although the Health Insurance Portability and Accountability Act (HIPAA) Opens New Window and other measures are intended to protect you from medical identity theft, there are things you can do yourself.

Guard your cards
While most of us are careful about our banking information and credit cards, be sure you are also cautious with your Medicare ID card and your Wellmark ID card.
Only give your Medicare number to doctors, pharmacists, other health care providers, your insurers, or people you trust to work with Medicare on your behalf.
Keep in mind, Wellmark will never ask you for payment over the phone or the internet. You will always receive a bill for your Wellmark coverage.
Protect your Social Security number
The ultimate goal for any identity thief is to collect your Social Security number. That's why it's so important not to share this number unless it is required. "Never provide your social security number by phone or email to anyone," says Reese.
What about health care providers?
When you fill out forms at your doctor's office or the hospital, you may be asked to provide your Social Security number. You may want to leave the area on the form blank, or ask why the clinic needs this type of information.
"Security practices vary among medical providers," says Reese. "While one office may be equipped to protect your medical records, another may not have adequate security in place. This can compromise your privacy and your security."
What about health insurance companies?
Most health insurers require your Social Security number when you enroll. That's because health insurers must send the Internal Revenue Service information about health plan members and their insurance coverage, including their Social Security number (or other tax identification number).
Review your health care statements
Look closely at bills and statements from your health care providers for unexpected items, services or health conditions. If you spot something that seems out of place, contact their office immediately. Other tips:
- Read the Explanation of Benefits (EOB) statement or Medicare Summary Notice you receive after treatment. Check that you actually received care from the provider on the dates listed. If not, contact your insurance company and report any inconsistencies. Want to easily access to EOBs online? It's easy. Just log in to or register for myWellmark® Opens New Window.
- Shred outdated or unwanted statements, prescriptions, and labels from prescription bottles.
- If you have access to a patient portal from your health care provider, look at your online medical records monthly.
Practice good online safety
- Create secure and unique passwords for online accounts including your myWellmark account.
- Avoid emailing personal information such as account numbers and social security numbers.
- Be cautious of links posted on social media sites and the information you release on the sites.
- Report lost or stolen cards.
- Do not click links in emails from unfamiliar senders.
- Do not reply to emails from unfamiliar senders.
Know phone safety tips
- Do not provide any information to unknown callers including name, telephone number, email addresses, social security numbers, or member IDs.
- Do not release personal health information such as current medications or medical records to unknown callers.
