Oregon Health Plan provider enrollment

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.

OHA requirements

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.

  • Starting September 3, 2019, 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. 

For changes

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.

OHA enrollment forms

All forms are fillable PDFs. Please fill out electronically. Handwriting is required for signature fields only. If you use Mozilla Firefox, you may need to change your download settings to see the fillable version.
