Highmark Health will grow by more than 350,000 members if state regulators approve a proposed deal to acquire sole ownership of Gateway Health. The acquisition would expand Highmark’s insurance rolls from 6 million to 6.355 million members, a nearly six percent increase. For nearly three decades, Highmark Inc., has owned 50 percent of Gateway, which is headquartered a few blocks from Highmark’s corporate high-rise in Pittsburgh. The remaining 50 percent of Gateway has been owned by Livonia, Michigan-based Trinity Health, whose provider network spans 90 hospitals and other services across 22 states. Gateway offers Medicaid, Medicare and dual-eligible coverage across Pennsylvania. Highmark’s proposed acquisition of Gateway comes just a few months after the insurer’s affiliation with HealthNow New York Inc. became effective. The newly affiliated organization — which expanded Highmark’s reach to four states — has been rebranded Highmark Blue Cross Blue Shield of Western New York and Highmark Blue Shield of Northeastern New York.
