The Oregon Health Plan is not the Affordable Care Act, but the two are closely linked: OHP is Oregon’s Medicaid program, and the ACA is what let the state open it to hundreds of thousands more low-income adults. So when people ask about the Oregon Health Plan and the Affordable Care Act, the short answer is that OHP existed before the ACA passed in 2010, and the federal law gave Oregon the funding and legal authority to extend that coverage much further than it had reached before.
Medicaid Expansion vs. the Marketplace
Most people hear “Obamacare” and picture HealthCare.gov, the private insurance marketplace where you shop for plans and may qualify for subsidies. That marketplace is one half of the ACA. The other half is Medicaid expansion, which gave states the option to cover adults earning up to 133 percent of the Federal Poverty Level. A built-in 5 percent income disregard pushes the effective threshold to 138 percent.
Oregon took the expansion. OHP is how the state delivers it. If your income is low enough, you don’t shop on the marketplace; you apply for OHP and, if eligible, get coverage with no premiums, no copays, and no deductibles.
What Changed in Oregon Because of the ACA
Before 2010, Oregon’s Medicaid program mainly covered specific categories of people: children, pregnant women, people with disabilities, and seniors. A working-age adult without children, no matter how little they earned, was generally shut out.
The expansion provision at 42 U.S.C. ยง 1396a(a)(10)(A)(i)(VIII) changed the eligibility test from category-based to income-based. Oregon accepted the federal funds and folded the newly eligible population into OHP. The state continues to run the program under its own rules while meeting federal standards, which is why OHP looks and feels like a state program even though its expanded reach is an ACA creation.
Who Qualifies for OHP Today
Eligibility now comes down to residency and income. Since July 1, 2023, immigration and citizenship status no longer affect whether someone qualifies. Under the Healthier Oregon program, people of all ages who meet the income and residency rules can receive full OHP benefits regardless of immigration status. Lawful permanent residents no longer need to wait five years. Receiving OHP is not treated as a “public charge” and will not affect anyone’s immigration case.
Residency
You have to live in Oregon and intend to stay. There is no minimum length of time you must have lived in the state. If you moved here with a job commitment or are looking for work, you count as a resident. Temporary absences like travel or school out of state don’t end your residency as long as you plan to return.
Income
Income is measured using Modified Adjusted Gross Income (MAGI) compared to the Federal Poverty Level. For most adults ages 19 through 64, the ceiling is 138 percent of the FPL. The 2026 monthly limits for adults are:
- Single individual: $1,836 per month
- Family of four: $3,795 per month
Children and pregnant adults qualify at higher thresholds, up to 305 percent of the FPL. Children between 139 and 305 percent of the FPL cannot have other minimum essential coverage and still qualify.
If your income is above the OHP limit, that’s where the marketplace side of the ACA takes over. You’d look at private plans and premium tax credits on HealthCare.gov instead.
What OHP Pays For
OHP is more generous than many people expect, and it isn’t a scaled-back version of insurance. There are no deductibles, no copays, and no monthly premiums.
Medical benefits include doctor visits, emergency care, inpatient and outpatient hospital stays, prescriptions, pregnancy care, mental health and substance use treatment, physical and occupational therapy (up to 30 visits per year), hearing aids, home health care, hospice, medical equipment such as wheelchairs and CPAP machines, and smoking cessation programs. Family planning services, including birth control and sterilization, are covered.
Dental coverage runs across all ages, which is unusual for a Medicaid program. It includes checkups, X-rays, cleanings, fluoride, fillings, extractions, stainless steel crowns on back teeth, full dentures every 10 years, partial dentures every five years, and specialist and emergency dental care.
If you had unpaid medical bills before you applied, OHP can potentially cover them. The state evaluates retroactive eligibility for up to three calendar months before the month you submitted your application, as long as you were eligible during those months. People often delay applying while they’re sick or in the middle of an emergency, not realizing OHP can reach back and pick up bills they’ve already incurred.
How to Apply
Oregon takes applications four ways, and free help is available through OHP-certified community partners if you want someone to walk you through it.
- Online: create an account on the ONE (Oregon Eligibility) system at one.oregon.gov. The same portal handles food, cash, and child care benefits.
- By phone: call ONE Customer Service at 1-800-699-9075, or call a local Oregon Department of Human Services (ODHS) office.
- By mail or fax: send a completed paper application to OHP Customer Service, P.O. Box 14015, Salem, OR 97309-5032, or fax to 503-378-5628.
- In person: visit a local ODHS office or an OHP-certified community partner.
Before you start, gather Social Security numbers and dates of birth for every household member, proof of income (recent pay stubs, W-2s, or tax returns), your tax filing status, and details about any health insurance you already have through an employer or a private plan. Tax filing status matters because it determines how household members are grouped for the income calculation.
The state generally processes applications within 45 calendar days after receiving a completed application, and many people hear back sooner. If more documentation is needed, you’ll get a request by mail or through your ONE account. Respond quickly, because your coverage start date depends on when the eligibility determination is finalized. Disability-based decisions can take longer than 45 days.
Once you’re approved, you’ll be enrolled in a Coordinated Care Organization within three business days. The CCO is your managed care plan, coordinating physical, dental, and behavioral health services depending on your enrollment type. If your county has more than one CCO, you can switch within the first 90 days; after that, you wait six months before changing.
Keep in mind that OHP has a 10-day reporting rule once you’re enrolled. Any change to the information on your original application, including income, household size, address, other coverage, or pregnancy, needs to be reported within 10 days. Missing those reports can cost you coverage or leave you owing the state money.
