One of my clients called and told me he received a call from a company indicating they were associated with his Medicare Advantage plan and that he needed to write a check for $299.90. I told him this was a scam. He had already written the check and was contacting the bank to cancel it. I also told him to report it to Medicare. Please let people you know who are on a Medicare plan to be suspicious of anyone who says they are contacting them from a health plan asking for information on their bank account and/or asking for check for $299.90. Ask for a phone number to call them back and then contact their plan directly.
