O&P Tree is the only resource on the market for O&P coding that does not require a membership, updates automatically, and is 100% free!
So, before using O&P Tree, how did you code? Did you rely on the "suggested" codes provided by manufacturers? Did you search the web for specific codes? Did you pay for a costly membership? Did you keep a cheat sheet of commonly used codes? Or purchase manuals every year? Please leave comments below.
