The Kaiser Family Foundation earlier this month released its calculations of the impact of the ACA on Medicaid and CHIP enrollment in the 50 states. The data takes a snapshot of pre-Obamacare Medicaid enrollment and post-Obamacare enrollment.
Open enrollment for health insurance through the Affordable Care Act’s health exchanges came to an end over the weekend (UPDATE: The Obama Administration has extended the deadline to Feb. 22 due to technical glitches with healthcare.gov). While enrollment numbers for the latest marketplace policies are not yet available, the impact of the health law can be seen in other data.
The Kaiser Family Foundation earlier this month released its calculations of the impact of the ACA on Medicaid and CHIP enrollment in the 50 states. So far, 28 states and the District of Columbia have agreed to expand their Medicaid programs.
The data takes a snapshot of pre-Obamacare Medicaid enrollment and post-Obamacare enrollment. Pre-ACA numbers were based on averages from July through September 2013. Post-ACA numbers were from March through November 2014.
Nationally, about 57.8 million Americans were on Medicaid or CHIP in 2013. By late last year, the number had ballooned to 68.9 million, an increase of about 17.5%. (Kaiser notes that that number is likely low because some states didn’t report data for the months surveyed.)
However, while 17.5% was the overall increase, many states exceeded that rate—by far.
Below is a list of the 12 states that have seen the highest increase in Medicaid enrollment, according to the Kaiser Family Foundation’s analysis.
