CPT® Code 86793

The CPT® Code 86793 refers to the laboratory test for the detection of antibodies against Yersinia, a genus of bacteria known for causing serious infections, including bubonic plague. This test is performed on a blood sample collected from the patient. The presence of antibodies indicates that the immune system has responded to an infection by Yersinia, suggesting either a current or past infection. The test is crucial for diagnosing infections caused by this bacterium, which can lead to severe health complications if not identified and treated promptly. Understanding the immune response through antibody testing is essential for healthcare providers in determining the appropriate course of treatment and management for affected individuals.
