Humana Group is one of the largest health insurance companies in the country. As such, their enrollment data being made available is extremely helpful in seeing where things stand and how they've changed nationally.
Today, Bob Herman of Modern Healthcare provided me with a link to Humana's latest SEC filing. In addition to a whole mess of financial info which is of little interest to me, there's also all sorts of year-over-year data about their enrollment numbers...including a very handy section about their individual market, broken out by ACA exchange-based, Off Exchange and even their non-ACA compliant enrollments (ie, "grandfathered" and/or "transitional" enrollees).
