CBC ICD-10-CM Codes

The ICD-10 code for a routine complete blood count (CBC) screening is Z13.0: Encounter for screening for diseases of the blood and blood-forming organs. This code is used when the CBC is performed as a preventive measure rather than for diagnosing a specific condition.

A complete blood count (CBC)is commonly ordered for a variety of conditions, including D64.9: Anemia, unspecified, D70.9: Neutropenia, unspecified, D72.819: Decreased white blood cell count, unspecified, and D72.829:Elevated white blood cell count, unspecified. Other diagnoses that may justify a CBC include infections, inflammatory diseases, blood disorders, and routine health evaluations.

The coding code for a complete blood count (CBC) is determined by the Current Procedural Terminology (CPT) codes used for billing laboratory tests. The two primary CPT codes for CBC are 85025 - CBC with automated differential and 85027 - CBC without automated differential).
