100 Most Influential People in Healthcare
Marilyn Tavenner, 65
President and CEO, America's Health Insurance Plans
- Compensation: NA
- Years on list: 5
As administrator of the CMS during the early years of implementing the Affordable Care Act, Tavenner is arguably America's foremost authority on the ACA. She's taken that expertise to AHIP, where health insurers big and small are struggling to make money on exchange patients while the industry argues over the merits of consolidation. In the year that Tavenner has led AHIP, giants Aetna and UnitedHealthcare Group have left the association. Meanwhile, Aetna is trying to beat back a U.S. Justice Department challenge to its merger with Humana and exchange losses mount for Aetna and United alike.
