Which section of the CPT manual lists the code for WBC with differential, automated?

The correct choice pertains to the Pathology and Laboratory section of the CPT manual, which is specifically designed to cover laboratory tests and procedures. Within this section, you will find codes that correspond to various laboratory analyses, including hematology tests such as the white blood cell (WBC) count with differential.

The WBC with differential test is a common blood test that provides valuable information about the types and relative amounts of different white blood cells in the blood, which can help in diagnosing and monitoring various health conditions. Since this test falls under laboratory services, it is logically categorized in the Pathology and Laboratory section where all relevant lab tests are outlined.

In contrast, the other sections do not encompass laboratory tests. The Radiology section is focused on imaging services, the Surgery section pertains to surgical procedures, and E/M Services is dedicated to evaluation and management codes. Thus, the right location for the WBC with differential, automated code is indeed found within the Pathology and Laboratory section of the CPT manual.
