# Oregon Medicaid Enrollment and Revalidation Notices > Oregon Medicaid enrollment: a 90 day average, a notice for each provider ID, reenrollment if over 30 days past inactivation, prescribers must enroll. Source: https://webillhealth.com/oregon-medicaid-provider-enrollment/ Publisher: WeBill Health Last updated: November 11, 2026 Oregon Medicaid ## Oregon Medicaid, enrolled and paid An active Oregon Medicaid ID, a revalidation returned before inactivation, and prescriptions and claims not denied for enrollment. [Request a Revenue Defense Audit](https://webillhealth.com/revenue-defense-audit/request/) The Oregon Health Authority (OHA) sends each enrolled provider a revalidation notice that covers only the provider name and Oregon Medicaid ID on it, and a revalidation that arrives more than 30 days after OHA made the provider inactive is processed as a reenrollment. OHA explains the process on its [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx). * Revalidation At least every 5 years under federal rules, with a notice that applies only to the provider name and Oregon Medicaid ID listed on it. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) * Late revalidation Received within 30 days of inactivation, it is processed as a revalidation; received after 30 days, it is processed as a reenrollment and the provider stays inactive until that is done. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) * Prescribers Prescriptions are covered only if the provider who writes them for Oregon Health Plan (OHP) members is enrolled with Oregon Medicaid. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) * Changes Updates go in within 30 days of the change; a new NPI or Tax ID from an ownership change needs a new application and brings a new Medicaid ID. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) * Application queue Choosing the correct application type puts an application in the correct queue for processing, according to the October 2026 guide. [Provider enrollment guide, updated October 22, 2026](https://www.oregon.gov/oha/HSD/OHP/Tools/Provider-Enrollment-Guide.pdf) * Processing time The October 2026 guide says applications are processed on average in 90 days from date received; the time can vary, and some organization provider types that need program approval may take longer. [Provider enrollment guide, updated October 22, 2026](https://www.oregon.gov/oha/HSD/OHP/Tools/Provider-Enrollment-Guide.pdf) * What we see in practice 45 to 90 days from submission to an active Medicaid ID. ## In the official words > Submit updates within 30 days of the change. [Oregon Health Authority](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) > All providers who write prescriptions for OHP members must be enrolled with Oregon Medicaid for their prescriptions to be covered by Oregon Medicaid. [Oregon Health Authority](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) ## Oregon sends one revalidation notice for each provider ID OHA sends the notice to the mail to address on file, and it applies only to the provider name and Oregon Medicaid ID listed at the top. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) Federal rules require revalidation at least every 5 years for all providers, including rendering, billing, ordering and referring providers. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) State Medicaid agencies may also revalidate more often, at their discretion. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) OHA must receive the forms by the due date listed on the notice. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) Providers complete the forms only if OHA sent a notice asking for them, or if their provider number is listed in the revalidation files on that page. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) Payable individuals who bill OHA directly use the OHA 3972 and OHA 3975, organizations use the OHA 3972, OHA 3974 and OHA 3975, behavioral health personal care attendants use the OHA 2521 and OHA 3975, and all other individuals use the OHP 3113 and OHA 3975. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) The files show the date OHA received a revalidation, whether it was completed and any inactivation date. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) ## How Oregon enrollment works, step by step 1. Check whether you are already enrolled. OHA provides an online tool that looks a provider up by National Provider Identifier (NPI). [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) OHA cannot enroll new providers without a 10 digit NPI, for providers subject to the NPI requirements. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) 2. Pick the right provider type. Rendering, ordering, prescribing and referring providers billed by an organization enroll as non payable providers. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) 3. Use one service location. An enrollment record allows only one service location, so a provider who works at several locations picks one. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) 4. Match type, specialty and application type. The guide calls it extremely important to select the correct provider type and specialty. [Provider enrollment guide, updated October 22, 2026](https://www.oregon.gov/oha/HSD/OHP/Tools/Provider-Enrollment-Guide.pdf) 5. Send updates within 30 days. Address, contact or taxonomy changes are due within 30 days of the change. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) The guide also says the correct application type is what puts an application into the correct queue for processing. [Provider enrollment guide, updated October 22, 2026](https://www.oregon.gov/oha/HSD/OHP/Tools/Provider-Enrollment-Guide.pdf) It says Provider Enrollment processes applications on average of 90 days from date received, that the time can vary, and that some organization provider types that need program approval may take longer. [Provider enrollment guide, updated October 22, 2026](https://www.oregon.gov/oha/HSD/OHP/Tools/Provider-Enrollment-Guide.pdf) Our own figure is separate from that average: 45 to 90 days from submission to an active Medicaid ID for an Oregon file whose provider type, specialty and application type match the forms. ## Oregon ties prescription coverage to prescriber enrollment OHA requires every provider who writes prescriptions for OHP members to be enrolled with Oregon Medicaid for them to be covered. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) A 2018 question and answer sheet says there is no streamlined process for providers already enrolled in other states, because providers must be enrolled in each state for claims to adjudicate. [Prescriber enrollment questions and answers, December 2018](https://www.oregon.gov/oha/HSD/OHP/Tools/Prescriber%20Enrollment%20Questions%20and%20Answers.pdf) That 2018 sheet also says a provider can choose to enroll with the CCO or with the state, [Prescriber enrollment questions and answers, December 2018](https://www.oregon.gov/oha/HSD/OHP/Tools/Prescriber%20Enrollment%20Questions%20and%20Answers.pdf) and that OHA would like all providers enrolled with the state so they can serve fee for service members. [Prescriber enrollment questions and answers, December 2018](https://www.oregon.gov/oha/HSD/OHP/Tools/Prescriber%20Enrollment%20Questions%20and%20Answers.pdf) Coordinated care organizations (CCOs) are the Medicaid managed care plans that serve OHP members, and OHA says to contact the plan with questions about plan enrollment and credentialing. [Oregon Health Plan provider enrollment page](https://www.oregon.gov/oha/hsd/ohp/pages/provider-enroll.aspx) ## Where Oregon enrollments lose money A revalidation that reaches OHA more than 30 days after inactivation is processed as a reenrollment, and the provider stays inactive until OHA finishes it. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) Failure to return the requested information may result in OHA ending the provider’s participation in Oregon Medicaid. [Oregon Health Plan provider revalidation page](https://www.oregon.gov/oha/hsd/ohp/pages/revalidation.aspx) The 2018 sheet said its prescribing edit would deny any prescription claim with an invalid or non enrolled prescriber ID, and the same sheet said the start of the requirement was delayed. [Prescriber enrollment questions and answers, December 2018](https://www.oregon.gov/oha/HSD/OHP/Tools/Prescriber%20Enrollment%20Questions%20and%20Answers.pdf) Confirm with OHA how the edit works today. The same 2018 sheet lists failure to be named on a claim as a billing, rendering or prescribing provider in the past 18 months as a cause of disenrollment.
