Official Description

Hepatitis C antibody;

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 86803 refers to a laboratory test specifically designed to measure antibodies against the Hepatitis C virus (HCV). This test is crucial for identifying individuals who may be infected with HCV, which is known to cause both acute and chronic liver inflammation. Hepatitis C can be transmitted through various means, including blood transfusions, needle sticks, sharing needles in both occupational and recreational contexts, unprotected sexual contact, and even from mother to child during pregnancy. Additionally, personal items such as razors or toothbrushes can also pose a risk for transmission. The test associated with code 86803 is particularly important for screening individuals who are at higher risk for HCV infection. The testing process involves obtaining a blood sample through a procedure known as venipuncture, which must be reported separately. The serum obtained from the blood sample is then analyzed using a qualitative chemiluminescent immunoassay, a method that detects the presence of antibodies. It is important to note that antibodies to HCV may not be detectable until approximately two months after exposure; therefore, if there is a strong suspicion of HCV infection despite a negative test result, it is recommended that the screening be repeated. Furthermore, if the antibody screen yields a positive result, it is essential to confirm this finding with additional testing, which is reported under CPT® Code 86804, utilizing a recombinant immunoblot assay for more definitive results.

1. Indications

The Hepatitis C antibody test, coded as CPT® 86803, is indicated for individuals who are at risk for infection with the Hepatitis C virus (HCV). The following conditions and situations warrant the performance of this test:

  • High-Risk Behaviors Individuals who engage in behaviors such as sharing needles or other drug paraphernalia, which increases the likelihood of HCV transmission.
  • Occupational Exposure Healthcare workers or others who may have been exposed to blood through needle sticks or other means.
  • History of Blood Transfusions Patients who have received blood transfusions or organ transplants prior to the implementation of routine HCV screening.
  • Unprotected Sexual Contact Individuals who have had unprotected sex with partners who are known to be infected with HCV.
  • Pregnancy Pregnant women who may transmit the virus to their infants during childbirth.
  • Personal Item Sharing Individuals who share personal items, such as razors or toothbrushes, that may have come into contact with infected blood.

2. Procedure

The procedure for conducting the Hepatitis C antibody test involves several key steps, which are outlined below:

  • Step 1: Patient Preparation Prior to the test, the patient may be advised to avoid certain medications or substances that could interfere with the test results. It is essential to ensure that the patient understands the purpose of the test and the procedure involved.
  • Step 2: Venipuncture A qualified healthcare professional performs venipuncture to obtain a blood sample from the patient. This involves inserting a needle into a vein, typically in the arm, to draw blood into a collection tube. The venipuncture must be reported separately from the laboratory test.
  • Step 3: Serum Separation Once the blood sample is collected, it is processed in the laboratory to separate the serum from the cellular components. This serum is what will be tested for the presence of HCV antibodies.
  • Step 4: Testing The serum is then subjected to a qualitative chemiluminescent immunoassay, which detects antibodies against HCV. This method allows for the identification of individuals who have been exposed to the virus.
  • Step 5: Result Interpretation After the test is completed, the results are interpreted. A negative result may necessitate retesting if there is a strong suspicion of HCV infection, while a positive result requires confirmation through additional testing.

3. Post-Procedure

After the Hepatitis C antibody test is performed, the patient may be advised on the next steps based on the test results. If the test result is negative, and there is a high suspicion of HCV infection, the healthcare provider may recommend retesting after a specified period. In the case of a positive result, further confirmatory testing is required, which is reported under CPT® Code 86804. This follow-up testing is crucial for accurate diagnosis and management of the patient's condition. Additionally, the healthcare provider may discuss potential treatment options and lifestyle modifications to reduce the risk of transmission and manage the infection effectively.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
