Humana's Medicare Advantage slate in Seattle for 2027: 13 plans, 6 going away

SEATTLE — Fall 2026. Humana is heading into the 2027 plan year with 13 Medicare Advantage plans in King County, the home county of Seattle, down from 19 this year, according to the CMS Medicare Advantage Landscape Source File for 2027. Six plans will not be returning, no plans are brand new, and two carry new names. For current Humana members, those changes are spelled out in the Annual Notice of Change (ANOC) that lands by late September, and the window to switch runs October 15 through December 7, 2026.

MyMedicarePlans.org is an independent consumer site, not Humana and not Medicare. We publish the plan counts and names exactly as CMS lists them so you can match them against what you see on medicare.gov.

Which Humana Special Needs Plans are available in King County for 2027?

Humana will offer 4 Special Needs Plans in King County for 2027: 3 Dual Eligible SNPs (D-SNPs) and 1 Chronic Condition SNP (C-SNP). There are no Institutional SNPs (I-SNPs) in the Humana 2027 lineup here.

The D-SNPs listed by CMS are Humana Dual Select H5619-165 (HMO D-SNP), Humana Dual Select H5619-166 (HMO D-SNP), and Humana Gold Plus SNP-DE H1036-325 (HMO D-SNP). The C-SNP is Humana Gold Plus - Diabetes and Heart (HMO C-SNP). All four include drug coverage.

D-SNPs are for people with both Medicare and Medicaid. C-SNPs are for people with specific chronic conditions. Eligibility is set by Medicare's rules, not by the carrier, and you can confirm whether you qualify at medicare.gov or by calling 1-800-MEDICARE.

What is new, renamed or not returning for Humana in Seattle in 2027?

For 2027 in King County, Humana has 0 new plans, 2 renamed plans, and 6 plans that are not returning. The two renamed plans, per the CMS files, are Humana Dual Select H5619-166 (HMO D-SNP), which was Humana Gold Plus SNP-DE H5619-166 (HMO D-SNP) in 2026, and Humana Value Choice (PPO), which was HumanaChoice H5216-428 (PPO) in 2026.

A renamed plan is not necessarily the same plan with a new label — benefits, cost sharing, networks and drug lists can also shift. The ANOC your plan sends by late September spells out exactly what is changing on your contract for January 1, 2027.

If you are in one of the six plans not returning, Humana and Medicare will send a non-renewal notice. You can pick another plan during the Annual Enrollment Period (October 15 – December 7, 2026) or use the Special Enrollment Period that applies when a plan leaves.

How do I check a Humana plan against my doctors and prescriptions before December 7?

The most reliable way to check any 2027 plan against your own doctors and medications is the Medicare Plan Finder at medicare.gov. Enter your ZIP code, add your prescriptions and your pharmacy, and the tool will show how each plan would handle them for 2027.

A few steps that save headaches:

• List your drugs with doses and refill frequency before you start. Plan Finder uses that to estimate your yearly drug costs under each plan.
• Call your doctor's office and ask which 2027 Medicare Advantage contracts they are in-network for. Networks can change year to year even if the plan name does not.
• Look up each plan's Evidence of Coverage and provider/pharmacy directory on the plan's own site. These are the documents that govern what is covered.
• If you prefer to talk to a person, call 1-800-MEDICARE (TTY 1-877-486-2048), open 24/7.

Nothing happens if you do nothing: your current plan renews for 2027 if it is still offered, with the changes described in your ANOC.

What 2027 Medicare figures should I know while I compare?

CMS has confirmed a few 2027 numbers you can rely on while you compare plans. The Part D out-of-pocket cap rises to $2,400 in 2027 (up from $2,100 in 2026). The Part D maximum deductible will be $700 in 2027 (up from $615 in 2026). The Part D national base beneficiary premium for 2027 is $41.33 — that is a formula input CMS uses, not what any particular plan charges.

A few 2027 figures have not yet been announced. The standard Part B premium and deductible for 2027, and the 2027 IRMAA income brackets, are typically published by CMS in the fall — usually November. Until then, be cautious of anyone quoting those numbers as final.

For 2026 reference: the Part D cap is $2,100, the Part D maximum deductible is $615, the coverage gap has been eliminated since 2025, and IRMAA surcharges start above $109,000 in income for a single filer. The Medicare Prescription Payment Plan, which lets you spread drug costs across the year in level monthly amounts, remains available.
