2025 HCPCS code G0307

Complete blood count (CBC), automated (Hgb, Hct, RBC, WBC; without platelet count).

Use G codes to represent temporary procedures and professional services. Do not report G0306-G0307 and 88361 with component tests. Use G0306 for CBC without platelets with differential. Use 85027 for CBC with platelet count.

Medical necessity must be established based on the patient's clinical presentation and the reason for ordering the test. The documentation should clearly support the medical necessity.

A lab analyst performs the technical aspects of the test, including operating the automated cell counter. A healthcare provider typically collects the blood sample.

IMPORTANT:G0306 (CBC without platelets with differential), 85027 (CBC with platelet count)

In simple words: This is a basic blood test that checks your red blood cells, white blood cells, and other components of your blood, but it doesn't include a check on the cells that help in clotting.

This code represents a complete blood count (CBC) test performed using automated methods. It includes the measurement of hemoglobin (Hgb), hematocrit (Hct), red blood cell count (RBC), and white blood cell count (WBC). Importantly, it does not include a platelet count. The test is typically performed on a whole blood sample collected in a tube containing an anticoagulant.

Example 1: A patient presents with fatigue and shortness of breath. A CBC is ordered to check for anemia., A patient has a suspected infection. A CBC is ordered to check white blood cell levels., A patient is undergoing chemotherapy. Regular CBCs are ordered to monitor blood cell counts.

The documentation should include the reason for the test, the date and time of collection, and the results of the test.
