It is the medical specialty devoted to the investigation of the immune system. Immune-related illnesses and disorders are diagnosed and treated using immunology tests and methods. These tests and treatments may use immunofluorescence, immunohistochemistry, flow cytometry, and blood, urine, or other body fluids.
Immunology CPT codes represent the precise tests and operations carried out by healthcare professionals in this area. These codes guarantee that patients obtain proper coverage and compensation for their care by enabling healthcare practitioners to bill for their services appropriately.
This article will provide you with significant CPT Codes in detail.
Most Common Immunology CPT codes
- 86000 – Qualitative or Semiquantitative Immunoassays
A medical procedure involving a qualitative or semi-quantitative immunoassay is identified by the CPT Code 86000. An immunoassay tests a biological sample like blood or urine for a specific substance.
- 86328 – Immunoassay for infectious agent antibody(ies), qualitative or semiquantitative
A single-step, qualitative, or semi-quantitative immunoassay for detecting antibodies to infectious agents is denoted by the CPT code 86328. Infections like HIV, hepatitis, and Lyme disease can all be detected using this test.
- 86769 – Antibody; severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19])
The COVID-19-causing virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is primarily targeted by CPT code 86769 for detecting antibodies. This blood test checks for viral exposure.
- 86485 – Immunology, diagnostic, testing or therapeutic; skin allergy test, per 10 tests
This code denotes a diagnostic procedure for determining allergies to certain items, such as food, pollen, or animal dander. The test includes applying a small amount of the purportedly allergenic chemical to the skin and recording the presence or absence of a reaction. This code covers ten skin allergy tests’ costs.
- 95004 – Under Allergy Testing Procedures
This code refers to a diagnostic procedure involving injecting tiny amounts of the allergen into the skin to detect allergies to particular substances. This test is frequently performed when ambiguous skin testing since it is more sensitive than the skin allergy test. This code covers the price of doing successive and incremental intradermal tests.
- 95165 – Report multiple dose vials of non-venom antigens
The administration of multiple dose vials of non-venom antigens for immunotherapy is documented using CPT code 95165. This code should be entered when a patient receives multiple doses of an antigen from a vial meant to be used on various patients. The number of doses delivered and the precise antigen must be reported when using CPT code 95165. The paperwork should also specify if the antigen was made on-site or came from an outside source.
- 86001 – Allergen-specific IGG quantitative and semi-quantitative
A medical laboratory test that examines a person’s blood levels of Immunoglobulin G (IgG) antibodies particular to certain allergens is denoted by the code 95165. Quantitative or semi-quantitative results depend on the laboratory’s procedure.
- 86431 – Immunology, diagnostic, testing or therapeutic; infectious agent detection by nucleic acid (DNA or RNA)
This code refers to a diagnostic procedure used to identify an infectious agent’s genetic material (DNA or RNA), such as a virus or bacteria, to determine its presence. This test can diagnose several infectious disorders because it is very sensitive and specific.
- 86900 – Immunology, diagnostic, testing or therapeutic; tuberculin test (Mantoux)
This code denotes a diagnostic procedure for tuberculosis (TB) screening. The injection site is checked for a reaction after a tiny amount of tuberculin is administered under the skin. This examination can reveal people who have been exposed to TB but may not be showing any symptoms.
- 95024 – Immunology, diagnostic, testing or therapeutic; patch or application test
This code refers to a diagnostic procedure that involves placing an adhesive patch or tape containing the allergen on the skin to detect allergies to particular substances. Any response is watched after the patch has been on the skin for a predetermined time.
- 86331 – Immunology, diagnostic, testing or therapeutic; hepatitis B surface antigen (HBsAg) screening
This code designates a diagnostic procedure for checking for the presence of the HBV surface antigen (HBsAg) in blood to screen for hepatitis B (HBV) infection. This examination is designed to identify those who might be HBV carriers and who might be at risk of spreading the disease.
- 87635 – Infectious agent detection by nucleic acid (DNA or RNA); severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
The SARS-CoV-2 virus, which produces COVID-19, can be found using this code, which amplifies nucleic acids (DNA or RNA) using a probe approach. This test, or a PCR test, determines whether a COVID-19 infection is active.
- 86790 – Antibody; severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (Coronavirus disease [COVID-19]); screen, multiple step method
This code uses a multi-step process to check whether a patient’s blood contains antibodies against SARS-CoV-2. This examination is designed to identify whether a patient has previously contracted COVID-19 and experienced an immunological response.
CPT (Current Procedural Terminology) codes are a standardized system medical professionals use to document and report medical procedures and services. They help ensure accurate billing and coding for insurance purposes. To ensure proper billing and reimbursement, healthcare professionals must use the correct CPT codes for immunology procedures. However, patients should focus on understanding their diagnosis and treatment options and not be overly concerned with the specific CPT codes associated with their care.
