If you aren’t able to type up your questions, make sure to write in clear, concise print, leaving plenty of space in between your questions. Be sure to include your contact information in any correspondence that you mail to your healthcare provider.

Before sending mail that contains important documents or your private health information, call ahead and make sure that you have the correct contact information. Mail that is sent to the wrong address is not always forwarded to the right place, especially in places that receive a high volume of mail.

When you call the Medicare hotline, you will first be directed to an automated system. The automated system will give you some options and will collect information about your request.

If you would like to speak to a Medicare agent, a person is always available, though you may have to wait on hold. Make sure to call when you’re in a comfortable position, and at a time when you’re able to wait on the phone for a while if you need to.

Have these items or information handy when you call Medicare:

Your Medicare card and claim paperwork

When you call Medicare, have information ready that your agent will request. This includes your Medicare membership number, claim paperwork, and other information related to your question.

Pen and paper

Make sure to have a pen and paper handy whenever you call Medicare. Write down your questions before you call. Take down the name of the person you are talking to and the time of your call, and write down answers to your questions so that you don’t have to call back again.

Ask a friend or family member to listen in

Remember that you can always request to have information sent to you in writing at the end of your call. If you have someone available who can help you, it may be wise to listen to the call on speakerphone. The other person should remain silent on the phone, but can take notes for you and prompt you with questions you wanted to ask.

Medicare has a hotline that you can call 24/7 for assistance with your health insurance questions. Private health care companies that supply Medicare Part D and Medicare Supplement plans also provide telephone assistance. Remember that plan availability varies by state, and you may have to do some additional legwork to find information on your specific private health insurance provider.

If you have a hearing condition or a disability that makes talking on the phone difficult, you can send a request for information via email or through the mail. You can also use a TTY line to get the help you need.

Even though Medicare can be confusing, reaching out and taking advantage of the resources available will get you closer to the answers you are looking for.
