Tomorrow is the last of my 6 pcp visits, and I'm really worried.

My visits aren't consecutive-- which, my bariatric resource nurse says is fine, they can be non-consecutive and go back up to two years. I have six visits over the past 12 months, and I haven't lost any weight. In fact, I've gained weight from my first appointment 12 months ago. I gained 20lbs between May of 2013 and August of 2013, then kept my weight steady for the remainder of the visits.

If you were me, would you go ahead and submit everything, or keep trying until you've lost weight?

Follow the instruction of your Doctor's coordinator. They deal with the insurance companies and are aware of what is required and what will get by.
