Elderly patient comes in for exam with several chronic diagnosis'. After the digital rectal exam the doc will test the stool sample to see if there is any blood or not. I'm having trouble finding a CPT and DX combination that works together. The problem seems to be that some of the codes are for "Colorectal Neoplasm Screening". This may or may not be true depending on what is causing the blood when it is found. How are you coding this? Thanks for your help with this!
