Early and Periodic Screening, Diagnosis and Treatment

Special Screening & Preventive Care for Trillium Members Under Age 21

The Early and Periodic Screening, Diagnosis and Treatment (EPSDT) program provides comprehensive and preventive health care services for OHP members from birth to age 21.

This program provides you with the care you need for your health and development. These services can catch and help with concerns early, treat illness, and support children with disabilities.

You do not have to enroll separately in EPSDT; if you are under age 21 and enrolled in OHP you will receive these benefits.

Starting in 2025, young adults with special Health Care Needs (ages 19-25) also qualify for EPSDT benefits.

The EPSDT benefit covers:

  • Any services needed to find or treat illness, injury, or other changes in health.
  • “Well-child” or “adolescent well visit” medical exams, screenings, and diagnostic services to determine if there are any physical, dental, developmental, and mental health conditions for members 0 through age 20.
  • Referrals, treatment, therapy, and other measures to help with any conditions discovered.

Want to learn more about the services available through EPSDT? Visit the Oregon Health Authority's EPSDT webpage for medical and dental periodicity schedules, detailed information about covered services, the history of the program, and additional resources for members and families.

If you or your family member needs EPSDT services, work with your primary care provider (PCP), primary dental care provider, or a care coordinator by calling 1-877-600-5472 (TTY: 711). They can help you understand your EPSDT benefits and connect you with the medical, dental, behavioral health, and other services you may need.

Under EPSDT, Trillium will not deny a service without first looking at whether it is medically necessary and medically appropriate for you. You should always receive a written notice when something is denied, and you have the right to an appeal if you don’t agree with the decision.

You can get free rides to and from covered EPSDT provider visits. For more information, call Trillium Member Services at 1-877-600-5472 or visit Trillium's Transportation webpage.

If you have any questions about EPSDT services, call Trillium Member Services at 1-877-600-5472 (TTY: 711). You can also find more information in the Member Handbook.
