Iowa: Medicaid expansion up to 80K (or possibly 100K?)

GAH!! That's three "solid numbers but vague definitions attached to them" articles in a row this evening:

Braley also used the debate as an opportunity to show that he has worked with Republicans such as Iowa Gov. Terry Branstad. The two worked together to expand Medicaid, giving more than 80,000 people health coverage who didn’t have it before. 

OK, that makes it sound like 80K newly added to Medicaid via ACA expansion. However, in an earlier Iowa update, it made it sound like IA has some sort of Arkansas-like "private option" thing going on which had 20,000 enrolled at that time. So...is the 80K referred to above in addition to those 20K, or are they included in it?

(sigh) Again, not sure how to handle this. Anyone familiar with the Iowa Medicaid situation, please feel free to chime in below. Either way, it sounds like I can safely bump Iowa's "strict expansion" tally up from 20K to at least 80K, anyway...
