The federal government subsidizes health insurance for most Americans through a variety of programs and tax provisions. In 2017, net subsidies for people under age 65 will total $705 billion, CBO and the staff of the Joint Committee on Taxation (JCT) estimate. This presentation provides an overview of CBO and JCT’s current baseline projections of health insurance coverage and how those projections have changed since March 2016, highlighting changes in Medicaid and CHIP enrollment and nongroup coverage. Presentation by Jessica Banthin, Deputy Assistant Director in CBO’s Health, Retirement, and Long-Term Analysis Division, at a Congressional Research Service seminar on CBO’s methods for developing cost estimates.
