Read Brian Duffant’s interview with HealthLeaders on the rationale and value of a Cigna and Express Scripts merger. Cigna probably hopes to achieve multiple objectives with the Express Scripts merger. The health plan most likely is looking to improve purchasing power, which will be enhanced by both the increase in lives under management as well as exposure to differing biopharmaceutical manufacturer rebates across the Express Scripts and Cigna books of business, he says. Higher rebates on similar products in one book of business versus another can serve as leverage for the plan to negotiate higher rebate levels across a broader book of business.
