The AMA states that there are over 500 changes to the 2015 CPT code system. This pace of change is another reason why your practice may need professional coding assistance. If you need to order the CPT 2015 Professional Edition from the AMA online store, please visit this link. You can also have the Coding Network conduct a free confidential audit for your practice. A Free Confidential Coding Audit Will Help You Get You Ready for 2015 CPT Changes. It May Also Keep You Out of Serious Trouble With The OIG & Third Party Payors, Prevent Recoupment, And Improve Your Bottom Line.
