The enrollment period offers Missourians a chance to change their Part D drug coverage or Medicare Advantage plans.
Missourians can ask questions by phone or arrange one-on-one counseling by calling 1-800-390-3330 or visiting missouriclaim.org.
"Plans can change from year to year, and what you had last year may not be what best suits your needs this year," said Lindley-Meyers.
The department is also warning people to be aware of the dangers of fraud and identity theft and offers the following safety information:
* Verify that a salesperson is a licensed insurance agent by calling the Insurance Consumer Hotline at 1-800-726-7390.
* Be cautious of door-to-door salespeople. Remember, Medicare has no sales representatives, and agents cannot solicit Part D or Medicare Advantage plans at your home without an appointment.
* Avoid salespeople who offer free lunches for listening to a sales presentation. Federal law prohibits offers of free meals in exchange for signing up for a plan or listening to a presentation on Medicare.
* Do not give out personal information to an unlicensed agent. Salespeople are not allowed to ask for your Medicare Number,
* Salespeople cannot ask for online payments and must send a bill. Once you decide to buy a plan and have verified the agent is licensed, then you may give the agent personal enrollment and billing information.
* A Medicare health or drug plan can call you if you're already a member of the plan. The agent who helped you join can also call you. A customer service representative from 1-800-MEDICARE can call you if you've called and left a message or a representative said that someone would call you back.
