Summary & Overview
CPT 0221U: Navigator ABO Blood Group NGS Test
CPT code 0221U designates a Proprietary Laboratory Analysis (PLA) for the Navigator ABO Blood Group NGS test from Grifols Immunohematology Center. The assay uses next-generation sequencing of specific gene regions to identify ABO blood group antigens, a clinically significant result that can reduce the risk of hemolytic transfusion reactions, organ transplant incompatibility, and perinatal blood-type complications. As a PLA code, 0221U applies to a single, manufacturer- or lab-specific test and signals specialized laboratory technology.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and coding practices for PLA tests vary among these payers; this publication summarizes payer coverage approaches, common billing modifiers, and clinical contexts where the test is applied.
Readers will learn what CPT code 0221U represents, why sequencing-based ABO typing is clinically important, and how payers commonly treat proprietary lab tests. The report provides benchmark insights on service setting and clinical use cases, highlights policy and coding considerations relevant to PLA codes, and outlines operational details for laboratory and billing staff to identify when this test is reportable. Data not available in the input: payer-specific coverage policies, reimbursement amounts, associated taxonomies, and ICD-10 diagnoses.
Billing Code Overview
CPT code 0221U is a Proprietary Laboratory Analyses (PLA) code for the Navigator ABO Blood Group NGS test offered by Grifols Immunohematology Center. The test analyzes specific gene sequences to determine ABO blood group antigens from a specimen such as blood. Results inform clinical decisions to minimize adverse blood–type incompatibility reactions in blood transfusions, organ transplants, and in pregnancy and newborn care.
Service type: Genetic sequencing-based blood group determination (Proprietary Laboratory Analysis)
Typical site of service: Clinical laboratory or specialized immunohematology reference laboratory; specimen collection in outpatient clinics, hospitals, or blood banks
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or neonate requiring precise ABO blood group determination to prevent transfusion or transplant incompatibility. A common scenario is a hospitalized patient with acute blood loss who requires transfusion and has discrepant serologic ABO typing results due to recent transfusion, hematologic disorder, or weak/subgroup A/B antigens. Another scenario is prenatal testing for a pregnant patient with a history of hemolytic disease of the fetus/newborn, or testing of a newborn with unexpected serologic typing results. The clinical workflow: a clinician orders the Navigator ABO Blood Group NGS test (0221U) through the hospital or reference laboratory. A whole blood specimen is collected and sent to the Grifols Immunohematology Center. The laboratory performs targeted next-generation sequencing of the ABO gene loci per the proprietary assay, interprets sequence variants to determine ABO antigen genotype, and reports results to the ordering clinician. Results assist transfusion medicine, obstetrics, neonatology, or transplant teams in selecting compatible blood products or managing maternal–fetal blood group incompatibility.
