Unspecified blood type, Rh positive

This code signifies an individual's blood type is known to be Rh positive, but the specific ABO blood group (e.g., A, B, AB, O) has not been determined or documented. It indicates a partial understanding of the patient's blood group serology, specifically regarding the D antigen.

This code is appropriate when a patient's Rh status is confirmed as positive, but the ABO type is either unknown, pending, or not relevant to the current encounter's documentation. It may be used in initial assessments where full blood typing is not yet complete, or when only Rh positivity is pertinent to the clinical decision-making.

• Do not use if the full ABO/Rh blood type is known and documented.
• Always seek more specific blood type codes (e.g., O positive, A positive) if available.
• This code should be used cautiously and ideally replaced with a more precise code once full blood typing results are obtained.
