What ICD-10 Codes Are Used for CBC?

A Complete Blood Count (CBC) can reveal many health conditions by looking at the quantities of different cells in a patient's blood. Here are some commonly used CBC ICD codes related to abnormal findings:

D64.9 - Anemia, unspecified: Used when the patient's CBC reveals a lower-than-normal number of red blood cells.
D70.9 - Neutropenia, unspecified: Used when the CBC shows a deficiency of neutrophils, a type of white blood cell.
D72.819 - Leukocytosis, unspecified: Used when there is an abnormally high number of white blood cells in the blood.
D72.829 - Lymphocytosis, unspecified: Used when there's an unusually high number of lymphocytes.
D72.1 - Eosinophilia: For high eosinophil count.
D75.81 - Primary thrombocytosis: For high platelet count.

Which CBC ICD Codes Are Billable?

The billability of each code can depend on the specifics of the patient's case and the insurer's policies.

Clinical Information

A Complete Blood Count (CBC) is a blood test that gives information about the types and numbers of cells in the blood, including red blood cells, white blood cells, and platelets.

CBC can help diagnose various conditions, from anemia and infection to cancer.
Health professionals often use it as a diagnostic test but also for routine health screenings.
Further tests are typically required to find the underlying cause if the CBC results are abnormal.

Synonyms Include:

Full Blood Count
Complete Hemogram
Blood Cell Analysis
Blood Cell Count
Total Blood Count

Abnormalities in a CBC test may include high or low levels of red blood cells, white blood cells, or platelets. The specific meaning depends on which levels are out of range.

Yes, CBC tests are generally accurate and provide valuable information about a person's health. However, like any test, there's a slight chance of a lab error, and unusual results are often rechecked.
