What CoreSource does

Luminare Health (formerly CoreSource) is a national third-party administrator of self-funded health benefit plans, serving approximately 600 clients and over one million members with more than 50 years of operating history. The company targets employers and organizations of all sizes, with specialized offerings for hospitals and health systems and for Tribal Nations. Core operations span four integrated products: Administration and Cost Containment (where expert claim analysts review high-cost claims to capture billing errors and negotiate savings, producing medical trend below industry benchmark), customizable Products and Solutions, Digital Tools and Reporting for medical/pharmacy/clinical/lifestyle data, and white-label Back Office Administration supporting direct-to-employer initiatives for health systems.

The technology stack centers on a self-funded health plan administration platform with digital tools for data tracking, reporting, and analytics across medical, pharmacy, clinical, and lifestyle domains. The platform is HITRUST Risk-Based, 2-Year (r2) certified and holds URAC and NCQA accreditations. Custom network administration, white-label capabilities, and specialized integration partner services are positioned as differentiators.

Luminare Health operates as a wholly-owned subsidiary of HCSC (Health Care Service Corporation), one of the largest customer-owned health insurers in the United States. Revenue is generated through administrative fees on self-funded plan management, claims processing, and cost containment services via a consultative, direct enterprise sales motion. Pricing is quote-based and tailored to client scale, with no public disclosure of pricing or revenue figures.
