Type O blood, Rh positive

This code identifies a patient's specific blood type as O positive. This is a fundamental characteristic of an individual's blood, determined by the presence or absence of certain antigens on red blood cells.

This code is used when documenting a patient's known blood type, particularly in contexts such as pre-transfusion workups, prenatal care, or for general medical records where blood type information is relevant. It may also be used in cases of blood donation or when assessing potential hemolytic disease of the newborn.

• Only assign this code when the patient's blood type is definitively documented as O positive.
• Do not use this code for unspecified blood types or for other O-negative blood types.
• This code is for informational purposes and typically does not impact reimbursement directly.
