Navitus Health Solutions recently announced a significant development in its transparency-driven pharmacy benefit management model. Beginning January 1, 2026, its clients will gain access to Costco Pharmacy’s cost-plus pricing for prescriptions at both retail and mail-order locations.
Under this model, drug costs are calculated based on Costco’s acquisition price, plus a fixed markup and a pharmacy service fee. For Navitus clients, this means direct access to the purchasing power of Costco, with the assurance that all savings are fully passed through under Navitus’ 100% pass-through PBM structure. Additionally, Costco cost-plus model clients will have the same clarity for brand and generic drugs across Costco locations.
The partnership also introduces a consumer-friendly convenience… members living within an hour of a Costco Pharmacy will be eligible for free same-day delivery through Instacart, expanding accessibility while reinforcing Costco’s reputation for efficiency and value.
Navitus emphasized that this heightened level of transparency equips payers with a powerful means to better control drug spend, while also ensuring clients benefit from fully auditable spending.
For the pharmaceutical industry, this partnership underscores the accelerating shift toward cost-plus pricing and transparent PBM models – an evolution that could fundamentally change how drug costs are managed across the healthcare system, particularly as stakeholders push back against longstanding frustrations with the traditional PBM approach.
