The Centers for Medicare and Medicaid Services (CMS) reminds Medicare Advantage Organizations to continue working with their contracted health care providers to review, update, and certify existing provider information in the National Plan and Provider Enumeration System (NPPES). 

Per CMS, when reviewing your provider data in NPPES, please update any inaccurate information in modifiable fields including provider name, mailing address, telephone and fax numbers, and specialty, to name a few. You should also make sure to include all addresses where you practice and actively see patients and where a patient can call and make an appointment. Do not include addresses where you could see a patient, but do not actively practice. Please remove any practice locations that are no longer in use. Once you update your information, you will need to confirm it is accurate by certifying it in NPPES. Remember, NPPES has no bearing on billing Medicare Fee-For-Service.  

If you have any questions pertaining to NPPES, you may reference NPPES here.
