The appropriate CPT code for a hemogram with a manual differential WBC count is 85610. This code specifically pertains to laboratory tests involving a complete blood count (CBC) that includes a differential white blood cell count. It reflects the examination and categorization of the different types of white blood cells present in the sample, allowing for an in-depth analysis of the patient's blood health.

While the other codes may pertain to different types of tests, they do not accurately represent the specific action of conducting a hemogram with a manual differential count. For instance, 80050 covers a general panel of multiple tests, including a CBC, but does not detail the specific manual differential aspect. The other codes, such as 83312 and 88304, relate to specific hematological or pathological tests that do not directly equate to the hemogram with a manual differential. Therefore, 85610 is definitively the correct choice as it precisely corresponds to the test being described.
