Screening for other disorders of blood and blood-forming organs

This code signifies a screening encounter for conditions affecting the blood or the organs responsible for blood production, other than those specifically classified elsewhere. It indicates that a patient is undergoing testing to detect potential, as-yet-undiagnosed hematologic abnormalities.

Use this code when a patient presents for routine screening tests, such as a complete blood count (CBC) as part of an annual physical, where there are no current signs, symptoms, or known diagnoses of a blood disorder. It is appropriate for general health screenings aimed at identifying asymptomatic hematologic issues.

• This is a screening code and should be used as the primary diagnosis when no definitive diagnosis is established at the time of the encounter.
• Do not use this code if the patient has symptoms or a known diagnosis related to a blood disorder; in such cases, code the signs/symptoms or the definitive diagnosis.
• Always sequence this code first when it represents the reason for the encounter, followed by any abnormal findings (e.g., elevated white blood cell count) if identified during the screening.
