I was looking up a code for ADHD, 314.01, and noticed a reference for "Coding Clinic: 1997, Q1, P8-9". What does this mean? From what I can tell, it is an American Hospital Association Coding Clinic guideline, but when I looked further, I saw that it is only mentioned on some ICD-9 codes. Does anyone have any information about this or can you refer me to a website for specific information on these guidelines? I don't remember ever discussing this in class. I tried googling it, but was not able to find anything that answered my question. Thank you!
