Summary & Overview
CPT 86922: Pretransfusion Crossmatch Using Antiglobulin Technique
CPT code 86922 represents an antiglobulin crossmatch performed by laboratory personnel to determine compatibility between a donor blood unit and a patient’s serum. This pretransfusion compatibility test is a routine and essential step in blood transfusion safety that helps prevent hemolytic transfusion reactions by identifying clinically significant antibodies. Nationally, compatibility testing is a standard component of transfusion services across hospitals and clinical laboratories and has implications for patient safety, blood inventory management, and billing practices.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the test, typical sites of service, common modifiers that may be used with laboratory billing, and which payers commonly reimburse for pretransfusion testing. The publication also outlines benchmarking and policy considerations relevant to payers and providers, clarifies coding nomenclature for billing teams, and identifies areas where input was not provided (for example, associated taxonomies, ICD-10 diagnoses, and related codes).
The content is intended for billing managers, laboratory directors, and policy analysts seeking a clear summary of CPT code 86922, its clinical purpose, and how it fits into national payer coverage and billing workflows. Data not available in the input is explicitly noted where applicable.
Billing Code Overview
CPT code 86922 describes a laboratory compatibility test commonly called a crossmatch. The procedure involves a laboratory analyst testing a potential donor blood unit against a patient’s serum using an antiglobulin technique to detect clinically significant antibodies and assess compatibility.
Service Type: Laboratory test — pretransfusion compatibility testing
Typical Site of Service: Clinical laboratory or hospital blood bank
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves a hospitalized adult who requires transfusion of packed red blood cells for anemia or acute blood loss. A pretransfusion compatibility test (antiglobulin crossmatch) is ordered by the clinical team when a compatible donor unit is needed. The blood bank receives a current patient serum sample and the selected donor unit sample. A laboratory technologist performs antibody screening and an antiglobulin (indirect Coombs) crossmatch to detect clinically significant alloantibodies and confirm compatibility prior to issuing the unit. Results are documented in the blood bank record, and a compatible unit is released to the nursing staff for transfusion. Common clinical workflows include emergent type-and-screen with immediate spin for urgent transfusion followed by an antiglobulin crossmatch when time allows, routine preoperative crossmatch for scheduled surgery, or repeat crossmatching when the patient has had recent transfusions, pregnancy, or positive antibody screens.
