I would like to learn coding specifically for Pathology and Laboratory on my own. I currently and learning to review CCI edits for laboratory and pathology. Part of my job description is to verify the QTY of units billed for pathology/labs CPT codes to justify adding a modifier. I struggle with some of the labs as they can include different tests, stains or markers and I am not sure what I am looking for. Are there any resources on the web that would be useful or any books? I can't seem to quite find what I am looking for. Today I am trying to identify stains for CPT code 88350 and I am not sure what I am looking for and spending so much time searching the web for help. Can anyone offer me any assistance? Thank you in advance for your help!
