Just to see how much it will change, take your current superbill and use the ICD-9 to ICD-10 converter on the ICD-10 page of the AAPC website. I recently did a page of our diagnosis codes most often used and realized that most of what we currently use (hand and wrist surgery) will be replaced with anywhere from 3 to 10 codes. If you are a practice that uses a lot of "LT", "RT", modifier 50 and digit modifiers for toes and fingers, be prepared --- if your physician is a "lazy" documenter, you are going to be asking a lot of questions. I am working with a physician now so that they understand what needs to be added to the office notes to help prevent some of the delays. Also, physicians who are "spoiled" to having all of their codes and charges entered at the end of the day may need to readjust their thinking since part of the new code system includes the types of bacteria involved in infections and specificity of location of where and how accident happens and some of that will mean waiting for cultures and path reports to come back before it can be properly coded. Read the article entitled "Diagnosis Coding Done Right" in the August, 2011 Coding Edge for more information about how important the right diagnosis code is now, not just under ICD-10.
