As the special enrollment period for health care coverage ends, the Better Business Bureau (BBB) is warning consumers of potential scammers aiming to steal their personal information.

The Bureau warns that scammers have great ways ways to make their tactics appear to be legitimate. Medicare scams can even come in the form of a brochure or a "cold call" to consumers' homes.

 The BBB has issued the following tips for consumers to avoid open enrollment scams:

-Be wary of anyone who contacts you unsolicited. Medicare or ACA representatives will never contact you via phone, email or in person unless you are already enrolled. Be especially cautious of threatening calls that require quick action or immediate payment.

-Decline promotional gifts in exchange for personal information. Never sign up with a broker who offers an expensive "sign-up gift" in exchange for you providing your Medicare ID number or other personal information.

-Beware of dishonest brokers offering "free health screenings." Some brokers will offer this to weed out people who are less healthy. This tactic is called "cherry picking" and is against Medicare rules.

-Guard your government issued numbers. Never offer your Medicare ID number, social security number, health plan info or banking information to anyone you don't know.

-Hang up and go to official websites. You can enroll or re-enroll in Medicare or in a marketplace health plan online.
