Language resources for providers

Our goal is to help you and members get the interpreting services that meet your needs. Your facility may find these resources to be useful. 

Our expectations for interpreting services

All contracted CareOregon Dental providers must make interpreting services available to CareOregon Dental members. Services must be available during and after hours for consultation and provision of care. While interpreting services can be scheduled with short notice, to ensure coverage, please schedule as soon as a member makes an appointment.

Interpreting services should be performed by certified and qualified interpreters. The interpreters may be on-staff or scheduled through a CareOregon Dental approved vendor. They may operate on-site, over the phone or via computer screen. Interpreting should not be provided by a member of the patient's family. Members should never be asked to bring their own interpreter.

Occurrences for which CareOregon Dental covers interpreting services

  • Onsite medical, dental or behavioral health appointments
  • Scheduling or rescheduling appointments
  • Appointment reminders
  • Appointment follow-ups
  • Relaying test results
  • Registration for procedures/admissions

Use only our approved vendors

CareOregon Dental pays for interpreting services so that members can access their covered health care services and benefits. We have contractual arrangements with approved vendors. Please use them when serving CareOregon Dental members. (Be sure to verify that your patient is covered by the Oregon Health Plan.) See “How to schedule no-cost interpreting.”

If providers choose to coordinate interpreting services themselves rather than through CareOregon Dental, they are responsible for paying for those services. CareOregon Dental pays only for interpreting services that providers coordinate through our approved vendors.

The enhanced Preventive Teledentistry Program supports access and patient engagement strategies through the implementation of video visit capabilities and the provision of preventive services, including home fluoride varnish application and oral hygiene instructions to meet the needs of our pediatric population. This supplementary program is made available to interested primary dental partners. For information on participation, implementation toolkit, or technical assistance, please email

Electronic HIPAA transactions

The AMA recognizes electronic health care transactions as a cost saving, efficient way to do business and allows physicians to refocus resources on patient care. The links below provide information regarding various electronic transactions such as submitting claims, receiving payments and remittance advices.

To access your remittance advice electronically:

To receive payments via Electronic Funds Transfer (EFT):

CareOregon provides a couple of options for electronic payment.

  2. 2. Enroll with Zelis Payment Network for ACH direct deposit payment or virtual credit card for a small fee (this is separate from CareOregon’s free ePayment ACH option noted above). To enroll with the Zelis Payment Network, go to their website at, or you can call them at 855-496-1571.
    • Please note: CareOregon is not involved in any relationship with providers and Zelis Payments. It is strictly between Zelis and you, the provider.

CareOregon Dental, in collaboration with our Primary Dental Provider Network, developed a streamlined practice tool with the most crucial elements needed to assist our dental providers in evaluating a patient's risk for developing caries and aid in the management of the disease. This tool is the product of extensive clinical dental leadership review of current evidence based CRA tools and discussion on best practices, resulting in a modified version of the American Dental Association’s assessment.

This tool will be used as part of a patient’s caries risk management plan and includes valuable information to be used as a part of motivational interviewing and patient/guardian oral health education. CareOregon Dental’s goal is to improve stratified data collection of our dental population to evaluate and improve health outcomes in our community over time. This tool will help identify populations with the highest risk, develop and implement strategies and evaluate the impact of targeted interventions.

Dental referrals

CareOregon Dental members are able to see specialists only by referral from their assigned primary care dentist (PCD). Referrals should be submitted via the Provider Portal. If you need access to the Portal, or are experiencing difficulties submitting a referral, please contact the CareOregon Dental team at or 502-488-2812.

Please include the appropriate documentation and pertinent information along with the referral, which includes:

  • Chart notes
  • Dental charting
  • Current radiographs
  • Medical history
  • Recent periodontal charting
  • Treatment plan

Referrals are processed within one to three business days, but can take up to two to four weeks if additional information is necessary or needs further review.

Prior authorizations

Prior authorization is not required for dental services covered under Oregon Health Plan (OHP). However, authorization may be needed for proposed treatment of non-covered dental services or when requesting to provide dental services that have restrictions and/or limitations or have not been approved via a referral.

Prior authorization requests should be submitted via the Provider Portal. If you need access to the portal, or are experiencing difficulties submitting a referral, please contact the CareOregon Dental team at or 502-488-2812.  Please include appropriate documentation and pertinent information along with the prior authorization request from the list above.

CareOregon Dental is always secondary to any primary insurance. To ensure proper coordination of benefits, please notify CareOregon Dental with a courtesy call if the member has primary dental insurance.

State and federal regulations prohibit billing Oregon Health Plan recipients for OHP-covered services, except for coinsurance, copayments and deductibles expressly authorized by the General Rules, OHP Rules and/or federal rules.

Members cannot be billed for the following covered services:

  • Services that were denied due to lack of an authorization.
  • Services that were denied because the member was assigned to a PCP other than the one who rendered the services.
  • “Balance billing” for the amount not paid to the provider by CareOregon.

Generally, a provider may legally bill an Oregon Health Plan recipient in the following three circumstances (refer to above OAR for other examples):

  • The service provided is not covered by OHP and the member signed a Patient Responsibility for Uncovered Services form before they were seen.
  • The member did not tell the provider that they had Medicaid insurance and the provider tried to obtain insurance information.
  • Signed DMAP Form 3165.
