ICD-10 code: Doctor's have to come up with codes for billing purposes - especially when we order tests. This system is called ICD-10. It is the 10th generation of the International Classification of Diseases if you really want to know. "Dx" stands for 'diagnosis', and Z12.31 is a breast cancer screening code for the mammogram. I'd ask the doctor more questions if you're still not sure.
