Johnson & Johnson has sued divisions of health insurer Cigna, accusing them of working with a drug-benefit middleman to drain J&J financial-assistance funds earmarked for patients taking some of its pricier drugs.
The move by J&J widens litigation the healthcare giant initiated in 2022 against a middleman, SaveOnSP LLC, and is a new flare-up of long-running tension over drug prices among manufacturers, insurers, pharmacy-benefit managers and other middlemen in recent years.
