Costco Expands Into Senior Healthcare With Medicare Advantage Partnership

Costco is testing whether it can work for health insurance too.
The company's membership model, proven for retail, is now being applied to Medicare Advantage plans.
Mark

Why would Costco, which sells groceries and gas, suddenly want to sell health insurance?

Mimi

Because the membership model works. Costco has trained people to pay an annual fee and trust that they'll get value. Seniors are the perfect customer for that—they're already members, they shop regularly, and they need healthcare.

Mark

But health insurance is complicated. Costco sells simple things.

Mimi

True, but they're partnering with Scan Health Plan, which knows how to run Medicare Advantage plans. Costco is just adding another service to the membership bundle. The complexity is outsourced.

Mark

Is this risky for Costco?

Mimi

Somewhat. They're entering a regulated industry where mistakes can be costly. That's why they're seeking regulatory approval and planning a multiyear rollout instead of jumping in everywhere at once.

Mark

Who benefits most from this?

Mimi

Seniors who already shop at Costco benefit from convenience—one membership covers shopping and healthcare. Costco benefits from deeper customer loyalty and a new revenue stream. Scan Health Plan gets access to Costco's member base.

Mark

What could go wrong?

Mimi

If the health plan performs poorly, it damages Costco's brand. If regulators reject the application or slow-walk approval, the timeline extends. And if seniors don't see value in it, the whole strategy fails.

Mark

So this is really about membership loyalty?

Mimi

Exactly. Costco isn't trying to become a healthcare company. It's trying to make membership more valuable by offering more services. Healthcare is just the next logical product.

  • Costco is moving beyond retail into Medicare Advantage, a heavily regulated and rapidly growing market serving tens of millions of American seniors.
  • The partnership with Scan Health Plan creates tension between Costco's brand simplicity and the labyrinthine complexity of insurance regulation and CMS approval.
  • Seniors already loyal to Costco's value-first ethos may find the prospect of bundling healthcare with their warehouse membership both appealing and disorienting.
  • A phased, multiyear rollout signals that Costco is proceeding carefully, using regulatory timelines as a natural brake on overextension.
  • If approved and scaled, the model could meaningfully shift how a large demographic selects health coverage — away from insurers and toward trusted consumer brands.

Costco, long a temple of bulk goods and membership loyalty, is now reaching into one of the most consequential corners of American life: healthcare for the aging. Through a partnership with Scan Health Plan, the warehouse giant is seeking regulatory approval to offer Medicare Advantage plans to its members, testing whether the trust it has built over decades in the aisles can extend to the clinic. It is a quiet but significant wager — that the membership model, which has governed how millions of Americans buy chicken and gasoline, might also govern how they navigate illness and old age.

Costco, the warehouse empire built on bulk goods and annual dues, has announced a partnership with Scan Health Plan to launch its own Medicare Advantage offering — a move that reframes what a membership can mean for the company's aging customer base.

The strategy is rooted in Costco's core insight: its real product has always been membership itself. That model has proven durable across groceries, fuel, and travel. Now the company is asking whether it can hold in healthcare. Medicare Advantage plans, private alternatives to traditional Medicare, are growing in popularity as the population ages, and Costco sees an opening to deepen member relationships by adding health coverage to its roster of benefits.

Scan Health Plan brings the regulatory and operational expertise that Costco lacks, allowing the retailer to lead with its brand and membership infrastructure while its partner manages the complexity of insurance administration. For seniors already comfortable in Costco's aisles, the ability to select a health plan through the same membership could reduce friction and increase loyalty.

The rollout is contingent on regulatory approval from the Centers for Medicare & Medicaid Services, and Costco is approaching the process in deliberate phases — testing the model, measuring member satisfaction, and building toward national scale only after the foundation is proven.

What distinguishes this entry from other retail forays into healthcare is the mechanism: Costco is not opening clinics or selling prescriptions. It is extending the membership itself. If the company can carry its reputation for value and transparency into a space where seniors often feel overwhelmed, it may not just sell health plans — it may quietly redefine how a generation accesses coverage.

Costco, the membership warehouse giant that built its empire on bulk toilet paper and rotisserie chickens, is making a calculated bet that seniors will pay dues for healthcare the same way they pay for everything else. The company announced a partnership with Scan Health Plan to launch its own Medicare Advantage offering, a move that signals the retailer's intention to become a more comprehensive service provider for its aging customer base.

The partnership represents a deliberate diversification strategy. Costco has long understood that its real product is membership—the annual fee that keeps customers returning. That model has worked for groceries, gasoline, and travel packages. Now the company is testing whether it can work for health insurance too. Medicare Advantage plans, which are private alternatives to traditional Medicare, have become increasingly popular among seniors, and the market continues to expand as the population ages. Costco's entry into this space suggests the company sees an opportunity to deepen its relationship with members by bundling healthcare alongside their warehouse shopping.

Scan Health Plan, the partner in this venture, brings existing expertise in Medicare Advantage administration. The collaboration allows Costco to leverage its membership infrastructure and brand loyalty while relying on an established health plan operator to handle the regulatory and operational complexity of insurance. For seniors already accustomed to shopping at Costco, the option to purchase a health plan through the same membership could simplify their decision-making and potentially increase their overall engagement with the company.

The company is currently seeking regulatory approval for a multiyear rollout of the program. This phased approach suggests Costco is being cautious about its entry into a heavily regulated industry. Medicare Advantage plans must navigate approval from the Centers for Medicare & Medicaid Services, and the timeline for expansion will depend on how quickly regulators move. The staged rollout also gives Costco time to test the model, gather data on member satisfaction, and adjust its approach before scaling nationally.

What makes this move significant is not just that Costco is entering healthcare—plenty of retailers have tried—but that it is doing so through its core membership mechanism. The company has spent decades building trust with customers around value and transparency. If it can translate that reputation into the healthcare space, where seniors often feel confused and vulnerable, it could reshape how a substantial portion of the population accesses coverage. The regulatory approval process will determine whether that bet pays off, and how quickly Costco can begin offering health plans alongside its other member benefits.
