CPT® Code 86900 is used to report ABO blood group typing, which determines a patient’s A, B, AB, or O blood type. This test is a fundamental component of transfusion medicine, preoperative preparation, and obstetric care.
This code represents the laboratory determination of ABO type only, not Rh typing or crossmatching, which are reported separately when performed.

- Patient identifiers and date of service
- Clinical indication for testing
- Specimen type (whole blood)
- Test performed (ABO blood typing)
- Test result (A, B, AB, or O)

Clear documentation supports accurate billing and patient safety in transfusion-related care.
Reimbursement and Coding Considerations
- CPT 86900 is generally covered when medically necessary
- Often billed with Rh typing (86901) and other compatibility tests when performed
- Diagnosis coding should support transfusion, surgical, or obstetric indications
- May be part of preoperative or hospital lab panels
- Frequency may be limited based on clinical need and payer policy
Always verify payer-specific immunohematology billing guidelines.
