National Provider Identifier (NPI) requirements
All providers subject to NPI requirements must have a 10-digit NPI. (Providers not subject to NPI, such as transportation providers, are not required to provide an NPI.)
The Oregon Health Authority (OHA) cannot enroll new providers without this number.
- To get an NPI, apply online at the National Plan and Provider Enumeration System (NPPES) website.
- To look up your NPI information, use the NPI Registry.
For initial enrollment
To bill OHA directly, find your provider description in the list below. Complete and fax all forms and documentation listed for your description.
For rendering, ordering, prescribing and referring providers, use "Non-Payable Provider" as the search term.
- Next year, any provider who writes a prescription for an Oregon Health Plan member must be enrolled with Oregon Medicaid in order for their prescriptions to be covered by Oregon Medicaid. To learn more about this requirement, read OHA's Prescriber Enrollment Questions and Answers.
To find out if you are already enrolled with OHA, use
OHA’s verification tool. Just enter your NPI.
Submit updates within 30 days of the change under the EDMS Coversheet.
- For changes in ownership, search for "Ownership change only."
- For other information updates, such as address, contact information, or taxonomy information, search for "Provider update."
For licensure renewal (re-credentialing)
Fax your new license directly to Provider Enrollment at 503-947-1177 (Salem). An EDMS Coversheet is not required.
For revalidation notices
See the instructions on OHA's Provider Revalidation page.
