NPI: Rendering Providers Required to Register NPI

October 9, 2008

Rendering Medi-Cal providers must register their National Provider Identifier (NPI) using their individual Medi-Cal provider numbers. Each member of a provider group must register their individual NPI separately from the group’s NPI. A provider group may register an individual provider’s NPI on their behalf, but the group must ensure that it uses the correct NPI and Medi-Cal provider number.

Rendering providers can register their NPI using the NPI Collection (NPIC) tool. After reviewing the important information on the “Register/Update/Inquire NPIs” page, providers can click the “Continue to Register/Update/Inquire NPIs” button at the bottom of the page to complete the NPI registration.

Rendering providers can also submit the National Provider Identifier Registration Form (DHCS 6218) to register their NPI. After completing the required information, return the form with the National Plan and Provider Enumeration System (NPPES) verification document to the address shown at the bottom of the form.

The NPIC tool and the National Provider Identifier Registration Form (DHCS 6218) may only be used to register an NPI when the initial NPI registration has not been completed. If a rendering provider’s NPI is already registered, then a Medi-Cal Supplemental Changes (DHCS 6209) form must be completed and submitted to Provider Enrollment Division (PED) for any NPI-related updates.  

Providers can call the Telephone Service Center (TSC) at 1-800-541-5555 by choosing option 16 and then option 18 to obtain forms, ask questions about NPI registration or verify a rendering provider’s registration status.
