Sooo, the Medicaid office's math wasn't wrong. What they did was add in the commission I got last month to my total which put me over! It's not a perfect comparison, but commission is a lot like tips. They're nice to get, but I'm not guaranteed to get it and definitely not the same amount every time!
Sooo, being good at my job (and making $12 over the max) cost me healthcare. What's next? The exchanges. I'll give them a call in the morning to see about a plan. Here's hoping that will go without a hitch because if there's an issue there... I've got to see if some combination of my employer and the hospital system I work with will accommodate me. I've got enough issues that I need health care coverage!
