You can apply for Oregon Health Plan (OHP) any day of the year; there is no open enrollment period. Most applications are decided within 45 days (90 days if a disability determination is needed), and coverage can be backdated up to three months before the month you applied if you were eligible then.

Ways to apply in Oregon

  1. Online through the state benefits portal or HealthCare.gov, which forwards Medicaid-eligible applications to Oregon. This is the fastest route.
  2. By phone with the Oregon Health Authority or the Marketplace call center (1-800-318-2596).
  3. In person at a county assistance office or through a certified application counselor at many hospitals and community health centers.
  4. By mail using the paper application downloadable from the agency website.

Documents to have ready

  • Social Security numbers for applicants
  • Proof of income: recent pay stubs, tax return, award letters
  • Proof of Oregon residency: lease, utility bill or ID
  • Proof of citizenship or immigration status (often verified electronically)
  • Current health insurance information, if any
  • For seniors/disabled: bank statements, vehicle titles, life insurance policies

After you apply

You will get a notice by mail or in the portal. If approved, you choose a managed care plan (where applicable) and receive an ID card within a few weeks. If denied, you have the right to a fair hearing; the deadline to request one is printed on the notice, usually 30–90 days.
