Am I required to complete and submit my Medicare enrollment application via Internet-based PECOS?

No. Physicians and non-physician practitioners continue to have the option to complete and mail the paper Medicare enrollment application to the appropriate Medicare contractor.

I’ve been enrolled in Medicare for a number of years, but when I access PECOS to update my enrollment, my information isn’t shown. Is this an error?

Even though some physicians and non-physician practitioners are enrolled in Medicare, their enrollment records might not be in PECOS. If they have not sent in a Medicare application to report any changes to their Medicare enrollment information within the past 5 years, they probably do not have enrollment records in PECOS. These individuals will need to submit an initial Medicare enrollment application.
