Type B blood, Rh negative

This code identifies a patient's specific blood type as Type B, with a negative Rh factor. This information is crucial for various medical procedures, especially those involving blood transfusions or pregnancies.

Use this code when documenting a patient's confirmed blood type for medical records, particularly in preparation for surgical procedures, blood product administration, or during prenatal care. It is also relevant for patients with conditions requiring frequent blood typing.

• Always ensure the blood type has been definitively determined through laboratory testing before assigning this code.
• This code is for informational purposes and does not represent a disease or injury.
• Do not code this if the Rh factor is unknown or if the blood type is not specifically B negative.
