The big one that comes to mind, that really matters in my opinion, is ICD-10. If I was a doctor or a practice looking to hire a biller/billing company, I would expect that biller/billing company to be completely educated on ICD-10, to the extent that if I knew nothing about it, they could educate me. And believe me, many doctors/practices are nowhere near ready for the conversion in October, assuming it is not delayed again.
