Nearly 15 million people enrolled in Medicaid or the Children’s Health Insurance Program between Oct. 1, 2013 and Jan. 31, 2016, increasing total enrollment in the programs by 26.5% since the start of the first open enrollment period for the Health Insurance Marketplace, according to a report released today by the Centers for Medicare & Medicaid Services. The preliminary estimate is based on 49 states reporting both January enrollment data and baseline data from July through September 2013. Nearly 72.4 million people were enrolled in Medicaid or CHIP in those states as of Jan. 31, with Medicaid expansion states showing a 35.5% increase and non-expansion states showing a 10.4% increase. The Affordable Care Act’s Health Insurance Marketplace launched its first open enrollment period in October 2013, and its third open enrollment period ended this January. Individuals can apply for Medicaid and CHIP through the Marketplace or their state’s Medicaid/CHIP agency. Medicaid and CHIP enrollment continues year round.
