June 2016 CMS Medicaid Report: Net increase of 15.2 million (actually 16.1 million)

Regular readers know that I used to regularly post an entry about the official CMS Medicaid enrollment reports every month, documenting the increase in Medicaid enrollment since ACA expansion went into effect. The numbers were increasing dramatically every month for nearly two years, but started slowing down last fall as most of the expansion states started maxing out on their eligible enrollees.

As of November 2015, there had been a net increase of 14.1 million people added to the Medicaid rolls since October 2013 (the month when ACA expansion enrollment began), plus another 950,000 people who had already been quietly transferred over to Medicaid from existing, state-funded programs prior to 2013 via other ACA provisions. I sort of forgot to post about the reports for awhile, but checked back in again for the May report, released back in July.

As of May 2016, total Medicaid enrollment had continued to quietly increase to a total of 72.5 million people, with 15.1 million of that being mainly due to the ACA (roughly 10 million via official expansion, 1 million transferrees and 4 million "woodworkers").

Last week CMS released the June report, and the numbers are only modestly higher vs. May:

• Nearly 72.7 million individuals were enrolled in Medicaid and CHIP in June 2016. This enrollment count is point-in-time (on the last day of the month) and includes all enrollees in the Medicaid and CHIP programs who are receiving a comprehensive benefit package.

(Note: About 8.4 million children were enrolled in CHIP in 2015, so that's around 64.3 million actually enrolled in Medicaid itself)

• 144,441 additional individuals were enrolled in June 2016 as compared to May 2016 in the 51 states that reported comparable May and June 2016 data.

The total continues to inch upwards by around 150,000 people per month. (Note: "51 states" is deliberate; it includes DC)

I should note that the July report will likely show a total Medicaid enrollment spike of over 400,000 people, since it should include a good 260,000 new enrollees in Louisiana alone; Louisiana's expansion program kicked off on July 1st). I expect total July Medicaid enrollment to break 73 million.

• Looking at the additional enrollment since October 2013 when the initial Marketplace open enrollment period began, among the 49 states reporting both June 2016 enrollment data and data from July-September of 2013, over 15.2 million additional individuals are enrolled in Medicaid and CHIP as of June 2016, more than a 27 percent increase over the average monthly enrollment for July through September of 2013. (Connecticut and Maine are not included in this count because they did not submit enrollment data for the July-September 2013 baseline period.)

(Again: Not all 15.2 million of these are specifically due to ACA expansion; see below for details)

• Among states that had implemented the Medicaid expansion and were covering newly eligible adults in June 2016, Medicaid and CHIP enrollment rose by nearly 36 percent compared to the July-September 2013 baseline period, while states that have not, to date, expanded Medicaid reported an increase of approximately 12 percent over the same period.

• These enrollment counts are in addition to the enrollment increases from the nearly 950,000 individuals who gained coverage as a result of the Affordable Care Act before open enrollment began. Seven states implemented an “early option” to expand Medicaid coverage to adults with incomes up to 133 percent of the FPL between April 1, 2010 and January 1, 2014, using new state plan authority provided by the Affordable Care Act or a demonstration under section 1115 of the Social Security Act building upon that authority.

As noted in the headline, it's a matter of perspective as to whether these 950,000 people should "count" as being covered "due to" ACA expansion, since most of them were actually transferred over from existing state-funded healthcare programs for low-income residents.

As for the 15.2 million figure, it's important to remember that in addition to those who are enrolled in Medicaid directly due to the ACA expansion provision, there are also several million people who were already eligible for Medicaid even without ACA expansion who have only signed up for the program because of the massive outreach/education program...aka, "woodworkers": Those who either didn't know they were eligible earlier, or didn't know what the enrollment process was, or were previously too embarrassed/ashamed to enroll, etc etc. My best guess as to how many people fall into this category as of last November was roughly 3.8 million.

I haven't written about woodworkers since back in May, when Kimberly Leonard of U.S. News & World Report confirmed that a good 2 million Medicaid enrollees counted as "woodworkers"...as of the end of 2014 only. Since then, all evidence suggests that this number has continued to grow steadily, so I feel pretty confident about that 3.8 million figure...and again, that's still 6 months out of date. I presume it's up to over 4 million by now, reducing the "strictly expansion" figure to around 11 million.

However, there's still one more category: Those who are newly eligible for traditional (non-expansion) Medicaid. These are people who, like woodworkers, would be eligible for Medicaid even without the ACA...but who only became eligible since October 2013 (that is, via normal life changes to income/employment/etc). I have no idea how many people this includes, but I can't imagine it would be more than 1 million at the outside. This leaves roughly 10 million people who are only enrolled in Medicaid specifically due to the ACA's expansion program.
