Obamacare or the Affordable Care Act [ACA] is NOT the same as Medicare.
If you have Medicare, there is need to do anything on October 1st.
ACA or Obamacare is for people who are not 65 or older who need insurance.
You might get called by those unethical scammers who will try to sell you something or get your information by telling you they can do something insurance-wise for you.
DO NOT LISTEN TO THEM
They want to steal your credit card information or identity
