UnitedHealth Group’s Optum Rx, The Cigna Group’s Express Scripts, CVS Health Corp.’s Caremark and Prime Therapeutics together control about 70% of the national PBM market in 2022, according to an American Medical Association (AMA) report released on Sept. 9.
Although the PBM industry’s trade group immediately criticized the report, pointing out that the nation’s largest physician trade group could be biased against PBMs, data from AIS Health’s parent company, MMIT, tells a similar story. And one leading health policy expert tells AIS Health that what the researchers found is “very reasonable” and consistent with other reports on the concentration and vertical integration in the PBM market.
