If you are a physician or non-physician practitioner who is enrolled in Medicare, or who is planning to enroll in Medicare, it is important that you protect your Medicare enrollment information from getting into the hands of dishonest and unscrupulous people. CMS Medicare Learning Network (MLN) has released Medicare Fee-For-Service (FFS) Physicians and Non-Physician Practitioners: Protecting Your Privacy – Protecting Your Medicare Enrollment Record as the first in a series of fact sheets designed to educate FFS providers about important Medicare enrollment information. This particular fact sheet advises FFS physicians and non-physician practitioners on how to ensure their enrollment records are up-to-date and secure.
