Oregon Medicare Advantage Plans for Chronic Conditions in 2027: 13 C-SNPs

SALEM, Ore. — Oregonians living with a serious ongoing health condition will have 13 Chronic Condition Special Needs Plans, or C-SNPs, to consider for 2027, according to the Centers for Medicare & Medicaid Services Landscape files. These plans sit within the broader Medicare Advantage menu — 95 MA plans statewide — alongside 7 Dual Eligible Special Needs Plans and 6 Institutional Special Needs Plans. Each C-SNP is offered in specific counties, so the plan a neighbor talks about may or may not be sold where you live.

What is a C-SNP and who qualifies in Oregon for 2027?

A C-SNP is a type of Medicare Advantage plan built around a specific chronic condition, and to enroll in Oregon for 2027 you must have a qualifying chronic condition that a provider verifies. CMS maintains the list of qualifying conditions — common examples include diabetes, chronic heart failure, and certain cardiovascular disorders — and the plan will ask your doctor to confirm the diagnosis after you apply.

Because C-SNPs tailor their drug lists, care coordination, and provider arrangements to one condition or a group of related conditions, they are not meant for every Medicare beneficiary. If a verification does not come back in time, the plan is required to follow CMS rules about continued coverage or disenrollment, so applying with your provider's cooperation matters.

How many C-SNPs are offered in Oregon for 2027, and which carriers offer them?

Oregon has 13 C-SNPs for 2027, offered by five carriers: AgeRight Advantage (1 plan), ATRIO Health Plans (1 plan), Devoted Health (7 plans), Humana (2 plans), and UnitedHealthcare (2 plans). That is counted statewide; the full plan list and county counts are shown in the tables on this page.

For context, the 13 C-SNPs sit alongside 7 D-SNPs (for people with both Medicare and Medicaid) and 6 I-SNPs (for people who live in or need an institutional level of care) within the state's 95 Medicare Advantage plans. Several of Devoted Health's C-SNPs are new for the coming plan year, which is one reason the C-SNP count looks different than it did a year ago.

Which chronic conditions do Oregon's 2027 C-SNP plan names mention?

Among Oregon's 13 C-SNPs for 2027, the only plans whose names identify a specific condition are the two Humana Gold Plus – Diabetes and Heart (HMO C-SNP) listings from Humana. Those names tell you the plan is built for people with diabetes and certain heart conditions.

The other C-SNPs in the state — from AgeRight Advantage, ATRIO Health Plans, Devoted Health, and UnitedHealthcare — do not state a condition in the plan name. To find out which condition each of those plans serves, look the plan up on the Medicare Plan Finder at medicare.gov, call 1-800-MEDICARE, or read the plan's Evidence of Coverage directly from the carrier. The table on this page lists every C-SNP plan name, its type (HMO, HMO-POS, or PPO), and how many Oregon counties it is offered in.

Is there a Special Enrollment Period for Oregonians with a qualifying chronic condition?

Yes. People with a qualifying chronic condition generally have a Special Enrollment Period that lets them join a C-SNP outside the Annual Enrollment Period, once the condition is verified. That SEP is tied to the diagnosis itself, so timing depends on when a provider confirms the condition rather than on the calendar.

For most other changes, the Annual Enrollment Period is the window to use: October 15 through December 7, 2026, with coverage starting January 1, 2027. If you enroll in a C-SNP and later lose the qualifying condition, CMS rules give you a grace period and a separate SEP to move to another plan.

How do I check whether a C-SNP is offered in my Oregon county for 2027?

Availability in Oregon for 2027 is county by county, so the fastest way to see what is sold where you live is to enter your ZIP code on the Medicare Plan Finder at medicare.gov or to call 1-800-MEDICARE (TTY 1-877-486-2048), which is open 24 hours a day, seven days a week.

The table on this page shows how many of Oregon's 36 counties each C-SNP is offered in — ranging from 2 counties (ATRIO Support Rx) up through 14 counties (DEVOTED C-SNP PLUS 009 OR), with UnitedHealthcare's two Complete Care C-SNPs and AgeRight Advantage Premier each listed in 11 counties. A plan listed statewide may still not be sold in your specific county, so always confirm by ZIP code before you decide.

Where can Oregonians get free help comparing 2027 Medicare plans?

Free, personalized help is available in Oregon from Medicare.gov and from 1-800-MEDICARE (TTY 1-877-486-2048), 24 hours a day, seven days a week. Those two resources can confirm which C-SNPs are offered in your county, what the qualifying condition is for each plan, and how to request a provider verification.

You can also go directly to a carrier for its own Evidence of Coverage, pharmacy directory, and provider directory. Those documents — not summaries — are the authoritative source for a plan's rules, costs, and network for 2027.
