What are Medicare Advantage plans in Oregon?

Medicare Advantage plans (Part C) are an alternative to Original Medicare (Parts A and B). Offered by Medicare-approved private insurance companies, these plans must legally offer the same benefits as Original Medicare, but often include additional routine benefits, such as dental, vision, and/or hearing coverage. 

What do Oregon Medicare Advantage plans cover? 

Oregon Medicare Advantage plans are legally required to cover all services covered by Original Medicare—including inpatient hospital care, doctor visits, and preventive screenings. However, according to data from the Kaiser Family Foundation (KFF), nearly all individual Part C plans provide supplemental benefits not included in Original Medicare. These commonly include dental, vision, and hearing care alongside wellness benefits like gym memberships and recurring over-the-counter (OTC) stipends for non-prescription pharmacy necessities. 

Types of Medicare Advantage Plans Available in Oregon 

When choosing a Medicare Advantage plan, it helps to familiarize yourself with the different types of plans. 

• Health Maintenance Organizations (HMO / HMOPOS): These plans require you to see doctors and hospitals within a defined network and get referrals for specialists. HMOPOS plans offer slight flexibility to see out-of-network providers for certain services at a higher cost.

• Preferred Provider Organizations (PPO): PPOs offer the flexibility to see any doctor or specialist without a referral. You will save money by using in-network providers, but you can still receive care out-of-network if the provider accepts Medicare.

• Special Needs Plans (SNPs): These plans limit membership to individuals with specific characteristics or health conditions. They tailor their benefits, provider choices, and drug formularies to serve people who are dually eligible for Medicare and Medicaid, reside in nursing homes, or have severe chronic conditions.

• Private Fee-for-Service (PFFS): PFFS plans do not use a standard network. Instead, the plan determines how much it will pay and how much you owe. You can see any Medicare-approved doctor who agrees to accept the plan’s payment terms before treating you.

According to the Medicare Payment Advisory Commission (MedPAC), around two-thirds of Oregon Medicare Advantage beneficiaries choose an HMO plan structure, with the remaining beneficiaries choosing a PPO or SNP plan.

2026-2027 Oregon Medicare Enrollment Periods 

Oregon Medicare beneficiaries should be aware of the designated enrollment windows that occur throughout the year. These are:

• Annual Enrollment Period (AEP) | October 15 to December 7: During this standard annual window, any Medicare beneficiary can join, switch, or drop a Medicare Advantage plan. Adjustments made during AEP take effect on January 1 of the upcoming year. 

• Medicare Advantage Open Enrollment Period (OEP) | January 1 to March 31: This enrollment period is exclusively for individuals already enrolled in a Medicare Advantage plan as of January 1. Enrollees may make a one-time change to transition to a different Part C plan or return to Original Medicare (with the option to select a standalone Part D prescription drug plan). 

• Special Enrollment Period (SEP) | Occurs Based on Qualifying Life Events: An SEP allows out-of-season coverage modifications without penalty. Common regulatory triggers specific to the Oregon market include:

• Relocation: Permanently moving to a new address outside your current plan’s designated service area, such as moving across county lines from Multnomah to Deschutes County, or relocating into or out of an Oregon long-term care facility.

• Loss of Creditable Coverage: Involuntarily losing existing health or prescription drug protections, such as retiring and leaving an employer-sponsored group health plan or union coverage.

• Subsidy and Program Changes: Gaining, losing, or experiencing an eligibility modification in state-managed assistance programs, such as Oregon Health Plan (Medicaid) status or federal Extra Help allocations.

State Resources for Oregon Medicare Beneficiaries

Navigating public insurance programs and long-term care networks can be challenging. The state of Oregon maintains two primary public programs to provide beneficiaries, families, and caregivers with objective, conflict-free guidance regarding their health care options

Senior Health Insurance Benefits Assistance (SHIBA)

Administered by the Oregon Department of Consumer and Business Services, SHIBA is a statewide network of certified volunteer counselors funded by the federal government. This program provides free, completely unbiased one-on-one counseling and advocacy. SHIBA counselors help enrollees understand Medicare rights, compare public plans with private Medicare Advantage options, navigate complex billing appeals, and identify potential instances of Medicare fraud or abuse. 

Aging and Disability Resource Connection (ADRC) of Oregon

Maintained by the Oregon Department of Human Services (ODHS), the ADRC serves as a centralized information gateway for older adults, individuals with disabilities, and their support networks. Oregonians can contact the ADRC helpline for comprehensive information and referrals regarding long-term supportive services. This includes guidance on local community resources, enrollment in state-managed Medicaid programs such as the Oregon Health Plan (OHP), access to family caregiver support groups, and options counseling to help seniors make informed, cost-effective decisions about maintaining independence at home or in long-term care settings.

Compare Medicare Supplement Plans in Oregon

While Medicare Advantage plans replace your Original Medicare coverage, they’re not the only alternative or supplemental option for Medicare beneficiaries. Oregon beneficiaries may choose to remain on Original Medicare and purchase a Medicare Supplement Insurance (Medigap) policy to cover gaps in costs such as coinsurance, copayments, and deductibles. Medigap plans offer more network flexibility than a Medicare Advantage plan, as they allow you to see any physician or specialist nationwide who accepts Medicare without network limitations or referrals.

Note: You cannot be enrolled in a Medigap plan and a Medicare Advantage plan at the same time.
