CPT codes representing component tests of CBC testing (with differential WBC testing) include: 85004 Blood count; automated differential WBC count 85007 Blood count; microscopic examination with manual differential WBC count 85008 Blood count; microscopic examination without manual differential WBC count
Elevated white blood cell count, unspecified. D72.829 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM D72.829 became effective on October 1, 2018.
Also, a differential white blood cell (WBC) count measures the percentages of different types of white blood cells. This hematology testing is commonly ordered by physicians to diagnose and treat a wide array of disorders such as liver, heart, and pulmonary disease, hemorrhage, dehydration, and infections.

MCV is the average RBC volume. It can either be directly measured or calculated from the Hct and RBC: MCV=Hct/RBC.
The CBC is a mainstay of clinical diagnostics and laboratory medicine. The test is so versatile that it’s the only clinical laboratory test with a National Coverage Determination (NCD) that lists the excluded diagnoses, rather than those covered. The components of the standard CBC are: Red blood cell (RBC) count. White blood cell (WBC) count.
MCHC is the measure of Hbg in RBCs and is calculated by dividing the Hgb by the Hct: MCHC=Hbg/Hct.
Hct represents the ratio of RBC volume to total blood volume, expressed as a percentage. For example, a Hct of 50 percent means that there are 50 mL of RBCs in 100 mL of blood.
Fanconi anemia – D61.09 Other constitutional aplastic anemia: Fanconi anemia is an inherited disorder that effects the ability of bone marrow to produce enough new blood cells or malfunctioning cells. As a result, patients experience anemia (D64.9 Anemia, unspecified ), bone marrow failure (D75.89 Other specified diseases of blood and blood-forming organs ), birth defects, and developmental or eating problems.
Sickle-cell disease – D57.1 Sickle-cell disease without crisis: Sickle-cell disease is a genetic anomaly of the Hbg. Hbg, the protein inside the RBC responsible for carrying oxygen, contorts into a sickle shape hindering the body’s ability to effectively oxygenate organ systems.
WBCs are made in the bone marrow and consist of different cell types. All types are nucleated and work to combat infections of various kinds. High WBC counts can be seen in:
