A retail brand moves closer to Medicare coverage

Costco is preparing to offer Costco-branded Medicare products through a partnership with nonprofit insurer SCAN Group, according to reports on August 18, 2026. The initial programme is expected to include Medicare Advantage plans in two states and Medicare Supplement, or Medigap, coverage in a third state.

The move would not make Costco an insurer. SCAN Health Plan would remain the organisation responsible for designing, administering and operating the insurance products under Medicare rules. Costco’s role is better understood as a branded distribution and service partner: it contributes a trusted consumer name, a large membership base and a network of pharmacy, optical and hearing-related services.

That distinction is important. A Costco brand may make a plan more visible to retirees, but coverage decisions, medical networks, formularies, appeals and regulatory compliance will still be determined by the insurer and by the individual plan contract.

An expansion of an existing relationship

The planned insurance products build on a partnership already under way. Costco is a preferred pharmacy in SCAN’s network, and the companies expanded their collaboration in 2025 around prescription savings, vaccinations, optical services, wellness benefits and Medicare education.

SCAN has also allowed some eligible members to use certain supplemental benefit funds at Costco. The retailer now accepts many Medicare Advantage prepaid benefit cards at its registers, though whether a particular card works depends on the health plan and the benefit category.

This existing infrastructure gives the partnership a practical starting point. A Medicare plan associated with Costco could, subject to approvals and plan-specific rules, make it easier for members to connect pharmacy prescriptions, eligible over-the-counter purchases, vision allowances and hearing-related spending with places they already visit.

For Costco, the initiative also fits its broader approach to member services. The company already markets insurance, travel and other third-party services alongside warehouse retailing. Medicare represents a more regulated and consequential extension of that model because consumers’ access to doctors, hospitals and treatments is involved.

Medicare Advantage and Medigap are not interchangeable

The reported launch includes two fundamentally different forms of Medicare coverage.

Medicare Advantage is private-plan coverage that delivers Medicare Part A and Part B benefits. Plans may also include prescription drug coverage and extra benefits such as dental, vision, hearing or allowances for eligible over-the-counter items. In exchange, members generally use a defined provider network and must follow plan rules. Depending on the service and plan, those rules can include referrals or prior authorisation.

Medigap, by contrast, supplements Original Medicare. It helps pay deductibles, coinsurance and other cost sharing for services covered by Original Medicare. It does not replace Original Medicare, and it is generally paired with a separate Part D prescription-drug plan if drug coverage is needed. A beneficiary cannot use a Medigap policy to supplement a Medicare Advantage plan.

This difference means the Costco label alone will not tell consumers which choice is better. Medicare Advantage can offer a lower premium and bundled extras, while Medigap can provide more predictable cost sharing and broader access to providers that accept Medicare. The appropriate option depends on an individual’s doctors, medicines, expected care needs, budget and willingness to use a network.

Why SCAN is a logical partner

SCAN is a mission-driven, nonprofit healthcare organisation focused on older adults. Its Medicare Advantage business already serves beneficiaries in California, Arizona, Nevada, Texas, New Mexico and Washington. The company has been expanding both its geographic footprint and its relationships with providers and retailers.

For SCAN, a Costco-branded programme creates a customer-acquisition channel in a Medicare market where consumer trust and distribution matter. Older adults are often confronted with a dense array of plan choices and marketing messages during enrolment periods. A familiar retailer can reduce the barrier to exploring a plan, particularly when pharmacy and supplemental-benefit services are already connected to that retailer.

For Costco, the initiative could deepen engagement with a demographic that values predictable pricing and convenience. It may also increase pharmacy, optical, audiology and eligible wellness purchases. However, the reputational stakes are higher than in a typical retail partnership. If members encounter narrow networks, unexpected out-of-pocket costs or difficulties securing approved care, they may associate those experiences with the Costco name as well as with SCAN.

Details matter more than branding

The early announcement leaves major consumer questions unanswered, including the participating states, exact plan designs, premiums, drug formularies, provider networks and whether a Costco membership will be required or provide any separate benefit.

Prospective members should not assume that all Costco locations, services or products will be included. Access to a Costco pharmacy, the ability to use a vision allowance at Costco Optical, and eligibility to spend an over-the-counter benefit card are separate plan-specific questions. In prior SCAN materials, the company has emphasised that other pharmacies and providers remain available in its network and that enrolment in its health plans does not itself provide a Costco membership.

The plans will also require applicable regulatory review and approval. Medicare Advantage products must meet federal requirements, while insurance products and marketing are additionally shaped by state rules. Plan benefits and availability can vary by county, not merely by state.

What consumers should compare

When the products become available, beneficiaries should compare them against all local alternatives rather than choosing on brand recognition alone. The most useful checks are straightforward:

  • Confirm that primary-care physicians, specialists, preferred hospitals and pharmacies are in network.
  • Check every prescription drug against the plan formulary and examine the pharmacy pricing tier.
  • Review the maximum annual out-of-pocket limit for Medicare Advantage, as well as copays for hospital, specialist and outpatient care.
  • Identify prior-authorisation and referral rules, particularly for services likely to be needed.
  • For Medigap, compare the standardised benefit letter, premium pricing method, availability of Part D coverage and medical underwriting rules for switching later.
  • Establish whether Costco membership, warehouse access or particular benefit-card arrangements are required for any advertised savings.

Medicare’s annual enrolment period normally runs from October 15 through December 7 for coverage beginning the following year. That gives consumers a defined window to evaluate any new Costco-SCAN offering alongside existing plans.

A test of retail trust in a regulated market

The initiative is notable less because a warehouse retailer is entering healthcare than because it brings a powerful consumer brand closer to the point where older Americans choose their health coverage. Costco’s reputation for value could draw attention to a smaller nonprofit insurer, while SCAN supplies the Medicare expertise and licensed plan operations Costco does not possess.

Its success will therefore rest on execution rather than novelty. Competitive premiums and retail-linked benefits may attract interest, but durable adoption will depend on comprehensive provider networks, clear plan materials, dependable member service and evidence that the benefits work as promised when members need care.
