Cigna completes deal for Express Scripts

Express Scripts, one of the largest pharmacy benefit managers in the country, is officially part of Cigna, the companies said today. The deal is valued at $67 billion, including Express Scripts' debt.

Why it matters: The three biggest PBMs in the country — Express Scripts, CVS Caremark and OptumRx — are now all housed within a bigger parent company that includes a health insurer (pending CVS' last-minute survival in court). Each conglomerate says combining a PBM and an insurer will save people money on drug costs, but there's room for skepticism.
