spacer HOW DOES A UPIN GET ASSIGNED? Top of Page
 
  • UPINs are assigned to physicians, non-physician practitioners and medical groups that bill Medicare Part B. When a provider applies for a Medicare billing number also known as a provider identification number in order to submit claims to Medicare Part B, the Medicare carrier submits a request for a UPIN via an electronic record to the UPIN Registry. The UPIN Registry processes the record, assigns the doctor a UPIN, and returns the record to the Medicare carrier.
spacer HOW CAN I FIND A PROVIDER IN MY AREA? Top of Page
 
  • There are numerous methods that can be used to search for a Physician, Non-Physician Practitioner, or medical Group on the UPIN Registry website. The user may input the specific UPIN of the individual if that is known. If the UPIN is not known, the website may be searched using the name information of the individual or medical group. The complete name information of the individual (last and first name) may be input, or the complete name of the medical group. The search may be conducted using the last name of an individual only, or the user may input as little as 2 characters of the last name (or medical group). In doing this, one must realize that the information returned from the search request will vary greatly depending upon what was input as the search criteria.


  • We have upgraded the UPIN Registry website based on popular demand. You may limit or refine the scope of a search on the UPIN Registry website by inputting the appropriate selection criteria. Inputting a specific state will narrow the search to providers with office locations within the state selected. This is accomplished by clicking on the “State”” field which displays all 50 states, and each specific Medicare jurisdiction (i.e., Guam or the Virgin Islands). The user may also search for an individual by using a specific “credential” type or a specific zip code. This will yield only those individuals having that particular type of credentials or practicing within the specified zip code. If the user does not input any information in the name fields when requesting these types of searches, the website will return ALL providers practicing within the specific state, zip code or having that type of credential. If the name fields are used in conjunction with other criteria, the website will return all individuals with that name found within the other selection criteria.
spacer WHOM DO I CONTACT TO HAVE INFORMATION UPDATED ON THIS WEB SITE? Top of Page
 
  • Information appearing on the UPIN Registry website is drawn from each Medicare Part B carrier’s provider enrollment files. To correct or update information appearing on the Registry’s website, please contact the appropriate Medicare Part B carrier that has jurisdiction for the practice location. Follow these instructions to determine the appropriate carrier: On the UPIN Registry “Home” page, click on the related link “CMS Carrier Directory”. This will take the requestor to the Centers for Medicare & Medicaid website. A map of the United States and its territories will appear. Click on the state or territory where the practice is located. The CMS website provides information required to contact that carrier (i.e., mailing address, telephone number, email etc.)
spacer WHOM DO I CONTACT TO HAVE INFORMATION REMOVED FROM THIS WEB SITE? Top of Page
 
  • See above answer.
spacer HOW CAN I FIND OUT IF A PROVIDER HAS BEEN EXCLUDED FROM THE MEDICARE PROGRAM? Top of Page
 
  • You should contact your local Medicare Part B carrier to determine this type of information. You may also use the related link on the UPIN Registry’s website to go directly to the Office of the Inspector General (OIG) website. The OIG website allows a user to access their “Exclusions Database”. The OIG Exclusions Database lists all individuals and businesses that have been excluded from participating in federally funded health-care programs. Bases for exclusion include convictions for program-related fraud and patient abuse, licensing board actions and default on Health Education Assistance Loans.
spacer CAN WILD CARDS BE USED AS SEARCH CRITERIA? Top of Page
 
  • There is not any symbol that can be used as a wildcard when searching by name. To search by name, the user need only input a minimum of 2 characters into the last name field. It is not required to input any data into the first name field to use the search capabilities of the website.
