    Health Care: Insurance and Managed Care

UnitedHealth Group serves more than 85 million patients worldwide with its health benefits and services and is the largest U.S. health insurer, surpassing the likes of Kaiser Foundation Group and Anthem. Their businesses don’t stop there. CEO Stephen Hemsley has been investing heavily in Optum, its health services arm that includes a pharmacy benefits manager (PBM) and health data analytics. While Optum represents only a third of the Minnesota-based company’s total revenues, the unit is growing fast. To bolster Optum’s pharmacy business, UnitedHealth acquired Catamaran for $12.8 billion in March, which more than doubled its PBM members to 65 million. The additional scale gives UnitedHealth more sway when it comes to negotiating drug prices with manufacturers. While drug spending has been relatively stable in recent years as generics replaced blockbuster drugs, the rise of specialty drugs for diseases like high cholesterol and hepatitis C has put increased pressure on PMBs to help employers rein in costs. Drug discounts are also beneficial for PMBs, including UnitedHealth, which keep a portion of the discounts they obtain from drug makers–sometimes as much as 15% of the negotiated rebates.
