How to become an Oregon Health Plan provider

National Provider Identifier (NPI) requirements

All health care providers subject to NPI requirements must provide their 10-digit NPI when enrolling as an Oregon Medicaid provider. (Providers not subject to NPI, such as transportation providers, are not required to provide an NPI.)
  • 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.

How to enroll with the Oregon Health Authority

If you want to bill OHA:

  • Complete and fax all forms and documentation listed for your description under an EDMS Coversheet (MSC 3970). Requests submitted without the EDMS Coversheet will not be processed or returned to you. Learn more about using the EDMS Coversheet.
  • If you are an out of state provider (more than 75 miles outside the Oregon border) seeking payment for services to OHP members, also include the claim you are seeking payment for.

If you do not want to bill OHA, but serve OHP members:

If you do not want to bill us, but need to be reported in our system for other reasons (such as obtaining Provider Web Portal or Automated Voice Response access, or rendering/ ordering/ prescribing/ referring services for OHP members), use "Non-Payable Provider" as the search term.

All forms are in PDF.
