2023 Evaluation & Management Updates Free Webinar
October 24th, 2022 - Aimee Wilcox
Congratulations on a successful 2021 implementation of the Evaluation and Management (E/M) changes! That was a big change, but now an even bigger change is headed your way for inpatient and all other E/M categories. How great is it that almost all of the E/M categories will now be scored based on medical decision making (MDM) or total provider time? Standardized scoring and one set of E/M guidelines has the potential of bringing about a change or improvement of provider fatigue due to over regulation and documentation burden.

Yes, You Have What It Takes To Lead Your Practice And Your Profession
September 20th, 2022 - Kem Tolliver
If you’ve been in any healthcare role for more than two years, you’ve seen quite a bit of change. And guess what, it’s not over. We are living and working in uncertain times. This climate requires each of us to step outside of our comfort zones to lead exactly where we stand. It’s not required of one to have a “title” to lead. What is required, however, is a willingness to trust your instincts, look for answers and rely on your team.
