Encntr screen for dis of the bld/bld-form org/immun mechnsm

This code signifies a patient encounter for the purpose of screening for conditions affecting the blood, bone marrow, spleen, and lymph nodes, as well as certain immune system disorders. This includes proactive testing to detect potential abnormalities before symptoms manifest.

Use this code when a patient presents for routine screening tests for hematologic conditions, such as a complete blood count (CBC) as part of a general health check-up, or for screening for immune deficiencies in asymptomatic individuals. It is appropriate when the primary reason for the visit is to rule out disease in the absence of signs or symptoms.

• Do not use this code if the patient has signs or symptoms related to a blood or immune disorder; in such cases, code the presenting symptoms or definitive diagnosis.
• This code is typically a primary diagnosis when the encounter is solely for screening.
• If an abnormal finding is identified during the screening, code the abnormal finding in addition to this screening code.
