CPT® Code 86971

Pretreatment of RBCs for use in RBC antibody detection, identification, and/or compatibility testing; incubation with enzymes, each

The CPT® Code 86971 refers to the pretreatment of red blood cells (RBCs) specifically for the purposes of detecting, identifying, and/or testing compatibility for RBC antibodies. This procedure involves incubating the red blood cells with enzymes, which enhances the ability to analyze the reaction between the RBCs and any suspected drugs present in the bloodstream. The process is critical in situations where a blood sample has tested positive for an antibody related to a drug, as it allows healthcare professionals to ascertain the presence of that drug and its potential interactions. By utilizing this code, medical coders can accurately document the enzymatic treatment of the blood sample prior to further examination, ensuring that the testing process is properly recorded and billed. It is important to note that if the components of the blood are separated before testing, a different code, 86972, should be used instead.
