Costco Medicare Supplement plans and member deals in 2026 are drawing attention after the warehouse giant announced a Medicare partnership with SCAN, but details are still limited. Here is what has been confirmed, what remains unknown, how Medigap actually works, and which Costco services are worth comparing when you shop for coverage.
On August 18, 2026, Costco and SCAN Group announced an expanded partnership to develop a series of products for older adults. The plan is a limited rollout. The companies said they will sell their jointly named Medicare Advantage products in two states and a Medicare supplement in a third. SCAN is described as one of the nation’s largest nonprofit Medicare Advantage plans focused on senior health care. post 1591749 +2
Costco’s pharmacy chief called it a pilot program. And the companies expect to launch a suite of senior-focused insurance products over the next few years. In other words, this is a start, not a nationwide launch. wftvwftv
If you came here for a Costco Medigap policy, here is the honest answer: the details are not public. An industry specialist pointed out that the state for the Medicare Supplement product has not been identified, and neither has the company that will legally underwrite it. He added that until those details are public, no one can responsibly say whether the plans will be better, worse or less expensive than competitors. insurance-forumsinsurance-forums
The same source warned that calling it a Costco Medicare Supplement plan tells consumers almost nothing about the policy they would actually own. That’s a fair caution. A brand name is not the same as a benefit design or a price. insurance-forums
Executives also said they cannot share specifics because of regulatory limits on disclosure until Medicare formally approves the plans. At the time of the announcement, the Medicare Advantage product was awaiting federal regulatory approval, so shoppers did not yet know specific premiums, provider networks, or state locations. I could not confirm a launch date or the states involved, so check Costco’s and SCAN’s announcements before you plan around any of this. www.wftv.com +2
Probably not directly. Membership won’t get shoppers a discount on the Medicare plans, because that’s against federal rules. Another summary noted that federal rules prohibit including a free warehouse membership. Be skeptical of any ad or agent suggesting a Costco membership comes with a cheaper Medicare policy.

The partnership is designed around services members may already use. SCAN’s CEO said the plans will integrate with Costco’s offerings across prescription drugs, vision, over-the-counter medications and hearing products. SCAN already works with Costco on some of this. The new effort builds on an existing relationship where Costco provides pharmacy and hearing services to SCAN members. wftvground
That is the most realistic “member deal” angle: if a plan makes it easier or cheaper to use Costco’s pharmacy, optical, or hearing departments, that could matter to you. But the benefit will depend on the specific plan’s rules, and those aren’t public yet. Don’t assume you’ll get a particular price or copay.
Whatever Costco eventually sells, it helps to understand how Medigap works.
Because Medigap benefits are standardized, the main questions for a future Costco-branded policy will be price, rate-increase history, the underwriting company’s financial strength, and customer service.
The announcement covers both. Medicare Advantage is a different model: an all-in-one plan with networks, copays, and often prior authorization rules, while Medigap supplements Original Medicare. Over 35 million people were enrolled in Medicare Advantage as of February 1, 2026, so Costco is entering a crowded market. ground
The questions industry watchers are asking include which two states will get the Medicare Advantage plans and how aggressively the plans will use prior authorization. Those answers will shape whether the plans are attractive. insurance-forums
Costco’s Medicare move is real, but for now it is a limited pilot with few public details. A Costco-branded Medicare Supplement plan is planned for one state not yet named, and a membership won’t give you a discount on premiums. The smart move is to understand Medigap, compare current options, and revisit Costco’s offering once plans are approved and published. In the meantime, the best “deal” is the one that fits your health, budget, and doctors.
