Dual Eligible in Oregon: Medicare and OHP in Deschutes County

October 31, 2026

Bend resident reviewing Medicare and OHP eligibility

Being dual eligible in Oregon means you have both Medicare and the Oregon Health Plan (OHP), the state’s Medicaid program. Medicare is your main health coverage. OHP can help pay your Medicare premiums, deductibles and coinsurance, and it covers some things Medicare does not, such as rides to appointments and dental care, according to the Oregon Health Authority. If you live in Bend, Redmond, Sisters, La Pine or anywhere else in Deschutes County, this guide explains how the two programs fit together, which plan types exist, when you can change coverage, and who can help you for free.

What dual eligible means in Oregon

Dual-eligible beneficiaries are enrolled in both Medicare and Medicaid. In Oregon, Medicaid is the Oregon Health Plan. The two programs are run by different agencies with different rules, which is why the situation confuses so many people turning 65 or already on OHP when Medicare begins.

The practical picture looks like this:

Medicare is your primary coverage. It handles hospital care (Part A), outpatient care (Part B) and, depending on your choices, drug coverage (Part D) or a Medicare Advantage plan (Part C).
OHP works as a second layer. It can help with what Medicare leaves you to pay and with services Medicare does not cover.

The Oregon Health Authority also advises that once you know you are or will be on Medicare, you should ask your local Aging and People with Disabilities office or Area Agency on Aging for help, because your OHP benefits may change or end. Do not assume your OHP coverage carries over unchanged on your 65th birthday.

Who qualifies for both Medicare and OHP

To count as dual eligible you must be enrolled in Medicare Part A and/or Part B, and you must be either a full dual or a partial dual. Partial duals may get help through Medicare Savings Programs without receiving full Medicaid benefits.

The categories that matter most for Medicare plan choices, as listed by CMS, include:

Full Medicaid
QMB (Qualified Medicare Beneficiary)
SLMB (Specified Low-Income Medicare Beneficiary)
Other specific groups defined by state and federal rules

Oregon’s administrative rules also describe an OHP benefit package called OHP with Limited Drugs, which is for clients eligible for both Medicare and Medicaid benefits. The “limited drugs” part exists because Medicare, not OHP, is the main source of prescription drug coverage for these members.

Income and asset limits change from year to year, so we do not list figures here. The agencies that determine eligibility publish the current numbers, and the offices in the last section of this article can run your situation against them.

What OHP can pay for when you also have Medicare

The main value of OHP for a Medicare member is cost-sharing help plus extras. The Oregon Health Authority says OHP can help pay Medicare premiums, deductibles and coinsurance, and that it covers services Medicare does not, such as rides to appointments and dental care.

For members in the QMB category, the state pays for Medicare cost-sharing. Under the QMB + OHP with Limited Drug benefit, members are not responsible for Part A or Part B copays, deductibles or coinsurance. That is a large difference for someone who would otherwise face 20 percent coinsurance on outpatient care.

If you use virtual visits, it also helps to know the telehealth copay rules that may apply to Medicaid members, so a video appointment does not bring a surprise.

Three points to keep in mind:

Your category decides your benefits. A full dual and a partial dual on a Medicare Savings Program do not receive the same help.
Providers must accept your coverage. Before you book with a specialist, confirm they take both Medicare and OHP, or the plan you choose.
Dental and vision gaps remain for many people. OHP covers dental care for eligible members, but Original Medicare does not, so it is worth understanding what you actually have. We help with dental and vision coverage for people who want to fill those gaps.

Dual Eligible Special Needs Plans (D-SNPs)

A D-SNP is a Medicare Advantage plan designed for people who qualify for both Medicare and Medicaid. OHP describes D-SNPs as Medicare Advantage plans that work closely with OHP benefits. In Oregon they are often offered through coordinated care organizations (CCOs), the groups that administer OHP benefits, which helps line up your Medicare and OHP coverage in one place.

What to check before you enroll

Plan details differ by county and by year. Before choosing a D-SNP in Deschutes County, compare:

Your doctors and hospital. Are your primary care provider, specialists and preferred hospital in the plan’s network?
Your prescriptions. Is each drug on the plan’s formulary, and at what tier?
Your Medicaid category. D-SNPs are tied to the Medicaid eligibility categories above, so confirm yours qualifies for the plan you are considering.
Extra benefits. Look at dental, vision, hearing, over-the-counter allowances and transportation, and what each requires of you.
Your OHP coordination. Ask how the plan coordinates with your CCO and OHP so you do not end up with two plans pulling in different directions.

CMS guidance notes that full-benefit dual eligibles can choose to enroll in or switch between integrated D-SNPs on a monthly basis. Rules for how often you may change plans are specific to your situation, so confirm yours with an agent or counselor before you switch.

D-SNP or Original Medicare with a supplement?

There are two broad routes. One is Medicare Advantage, including a D-SNP, which bundles coverage under a single plan with a network. The other is Original Medicare, sometimes paired with a Medigap policy and a stand-alone Part D plan. For someone whose OHP already covers most cost-sharing, a Medigap policy may overlap with what the state pays. For someone who is not fully covered by OHP, such as a partial dual, the answer can be different. That is exactly the kind of comparison to run with a person who knows your numbers. Our Medicare supplement plans page shows how Medigap works when it does fit.

When you can enroll or change coverage

Medicare’s annual enrollment period runs from October 15 to December 7 each year. During those weeks you can sign up for or change a Medicare Advantage (Part C) or prescription drug (Part D) plan. Changes you make generally take effect the following January 1.

Programmes that help with Medicare costs work differently: you can apply for them any time of year. Do not wait for the fall window if you think you might qualify for OHP or a Medicare Savings Program. To start, contact a local Oregon Department of Human Services (ODHS) office for help with OHP or Medicare Savings Programs.

We keep plain-language guides on timing, including Medicare enrollment periods, key annual enrollment dates and rules and what changes to your Part D costs mean at open enrollment. If you are about to turn 65, our step-by-step guide to turning 65 walks through the order of events.

Already on Medicare and paying too much for Medigap?

Some Deschutes County residents hold a Medigap policy and later find they qualify for more help, or simply pay more than they need to. Oregon has a rule that helps here. Under the state’s Medigap birthday rule, you may switch to a different company’s policy of the same plan type, or one with lesser benefits, from 30 days before through 30 days after your birthday, regardless of your health. No medical underwriting is required for that switch.

The rule applies to Medicare supplement policies issued after January 1, 1990, and self-funded employer-sponsored group plans are not eligible. If you are weighing a switch, these pages cover the details:

If you are on Medicare Advantage and want to go back to Original Medicare, read about the Medicare Advantage disenrollment period first. Moving without a plan in place can leave you short.

Our perspective: why dual eligible members need a person, not a pamphlet

We are a local agency in Bend, and the dual eligible question is one of the most misunderstood we hear. People are often told two things at once: that Medicaid “covers everything” and that Medicare “covers everything.” Neither is quite right. What you receive depends on your category, your plan type and your doctors, and a wrong choice in the fall can follow you for a year.

Our approach is education first. We do not run a call center and we do not push a plan. We sit down with you, in person in Central Oregon or remotely, and walk through how Medicare Parts A, B, C and D interact with OHP, what your deadlines are, and which questions to put to each plan. Consultations are free. If the right answer for you is a D-SNP, we help you enroll. If it is Original Medicare with a Medigap policy, we help with that instead. We are paid by carriers when a client enrolls through us, never by you, and our job is to make sure that what you choose is something you understand.

We also believe in using every free resource around you. SHIBA counselors and ODHS caseworkers are good at what they do. An agent adds the part they cannot: comparing specific plans and recommending one.

FAQ

Is OHP the same as Medicaid in Oregon?

Yes. The Oregon Health Plan is Oregon’s Medicaid program. When you have both Medicare and OHP, Medicare is your main health coverage and OHP can help pay Medicare costs and cover some additional services.

Do I lose OHP when I turn 65?

Not automatically, but your OHP benefits may change or end once Medicare starts. The Oregon Health Authority advises contacting your local Aging and People with Disabilities office or Area Agency on Aging as soon as you know Medicare is coming.

Can I apply for help with Medicare costs outside open enrollment?

Yes. Programs that help with Medicare costs can be applied for any time of year. Only changes to Medicare Advantage and Part D plans are tied to the October 15 to December 7 annual enrollment period.

Can a SHIBA counselor tell me which plan to pick?

No. SHIBA counselors provide free, unbiased information but cannot recommend a plan. Only licensed insurance agents can recommend one, which is why many people use both.
