I'm a new coder (just finishing the course....exam on April 4th!! yikes!! )and I work for a Bariatric Surgeon. He does a whole slew of regular labs every year following bariatric surgery (for the rest of their life). I've been using 579.3 and 579.9 as dx codes, because usually the pre-op dx codes don't apply any more (morbid obesity, hypertension, sleep apnea, etc.) because they've been resolved with the surgery. Because he does so many, it can be pretty expensive, and some insurances don't cover it. I'm wondering if using V72.6 would be appropriate and if it would help the patients get it covered? Has anyone had any experience with this? Thanks
