The Cigna Group is a health insurer and pharmacy benefit manager, combining traditional health insurance plans with Evernorth, a health services division that includes Express Scripts, one of the largest pharmacy benefit managers in the country. Pharmacy benefit managers negotiate drug prices and manage prescription drug benefits on behalf of employers and health plans, a business that has become an increasingly significant and controversial part of the healthcare supply chain. Cigna sells health insurance primarily to employers and government program participants rather than focusing heavily on the individual insurance marketplace the way some competitors do. The combination of insurance and pharmacy benefits management gives Cigna visibility and negotiating leverage across more of the healthcare dollar, though the two businesses face different competitive and regulatory pressures.
