CPT 85025 | Complete Blood Count Test (CBC) With (Automated) Differential

CPT code 85025 describes a complete blood count automated test. The test includes multiple measurements of the patient’s blood cells to diagnose and manage various diseases.

What Is CPT Code 85025?

CPT 85025 can be used for billing complete blood count (CBC). This routine blood test provides detailed information about various types of cells in a patient’s blood.

A pathologist or a laboratory technician typically conducts the test to evaluate the patient’s overall health.

It provides a broad overview of the red blood cells, white blood cells, and platelets in a person’s blood and is vital for diagnosing and managing many diseases.

The 85025 procedure is done by analyzing a small sample of the patient’s blood using an “automated analyzer.” This is a machine that analyzes blood cells.

The automated analyzer counts the number of red blood cells (RBCs), white blood cells (WBCs), and platelets in the sample. It also calculates the hemoglobin (Hgb) and hematocrit (Hct) levels.

In addition, an “automated differential WBC count” is also included in this procedure. This helps to measure the number of different types of white blood cells present in the sample, providing important information about the patient’s immune system function and possible infections.

Therefore, the CPT code 85025 refers explicitly to the Complete Blood Count automated test that includes: Hemoglobin, Hematocrit, RBC count, WBC count, Platelet count, and automated differential WBC count.


The CPT book describes CPT code 85025 as: “Blood count; complete (CBC), automated (Hgb, Hct, RBC, WBC, and platelet count) and automated differential WBC count.”

What Is A Blood Count?

A Complete Blood Count (CBC) is a routine blood test that physicians commonly order to gain a comprehensive understanding of the different types of cells present in a patient’s blood.

The 85025 test is typically conducted by a pathologist or a laboratory technician, who will use specialized equipment to analyze the patient’s blood sample.

Collecting a blood sample for a CBC typically begins with inserting a needle into a vein on the patient’s arm.

The blood is then drawn into a syringe and transferred to a test tube containing an anticoagulant such as EDTA or citrate.

This helps to prevent the blood from clotting and allows for accurate analysis. The blood samples are then transported to the laboratory for analysis.

Nowadays, the counting process of the cells is primarily done in an automated way, which uses a computerized analyzer.

This machine counts the number of cells in the blood sample and provides accurate results.

The results are printed out for review by the physician, who can then use this information to make more informed decisions about the patient’s treatment and care.

This test is essential for detecting anemia, infections, and blood disorders and is also commonly used as a screening tool for cancer and other illnesses.


Analyzing a patient’s blood using flow cytometry is a precise and intricate procedure.

The examining physician or lab technician begins the 85025 procedure by carefully obtaining a small sample of the patient’s blood, using a sterile technique to ensure the sample is not contaminated. Next, the blood sample is placed into the flow cytometry instrument’s narrow tube.

Inside the instrument are various sensors, light detectors, and electrical impedance devices working together to analyze the blood sample accurately.

Using flow cytometry, the sensor counts the number of different types of cells passing through the tube and then uses the information it gathers to identify the type of cells present.

The procedure of counting, measuring, and analyzing blood cells is a critical step in this process. It allows the physician or lab technician to gain valuable insights into the patient’s overall health and well-being.

Additionally, this procedure often includes an “automated differential count of WBC” (white blood cells).

This allows the technician to quickly and accurately measure the number of white blood cells in the sample, which can provide important information about the patient’s immune system function.

Once the analysis is complete, the final result is sent to the computer for review by the physician or lab technician.

The results can be printed out for the physician’s records and the patient’s medical file.

With this information in hand, the physician can make more informed decisions about the patient’s treatment and care and can take steps to address any issues that may have been detected during the analysis.
