"I did revenue cycle consulting for 20 years before I came to ProHealth Care. I’ve worked with a lot of different systems and efficientC is one of the top systems I’ve ever worked with as far as having data and tools at your fingertips and being able to use it to solve root cause issues.”

Curt Glaunert, Vice President of Revenue Cycle, ProHealth Care
"I’ve chosen efficientC as my clearinghouse at two hospitals, the first was on Medhost and currently we are on Epic. efficientC has proven invaluable in reducing A/R and denials at both. My most recent implementation was seamless, and their customer service team continues to provide one of the most positive experiences I’ve had with a business partner in my career. To any hospital looking for a better approach to revenue cycle management, I can't recommend efficientC enough!”

"efficientC’s Insights dashboards have been a game changer for our business office. We have been able to extract data that we previously couldn’t access through our EMR. Insights has allowed us to reduce the amount of edits and repetitive denials we have even further to allow more time for us to work on other job duties."

"We’ve been working with OS, inc and efficientC for about two years. The piece I most value in our partnership is how they help find solutions to common problems as well as those that may be more complex or individual to our facility. The two companies collaborate together with what is happening in the industry and with their clients. This provides better information and a better product for everyone.”

"The switch to efficientC was a great move for us. The results have been very positive. In fact, after an employee left our team, we did not need to replace that position because of the improved workflow using efficientC.”
