The CPT® Code 86147 refers to the laboratory test for cardiolipin (phospholipid) antibodies, specifically measuring each immunoglobulin (Ig) class, which includes IgA, IgG, and IgM. This test is conducted on a blood sample to identify the presence of these antibodies, which are associated with various medical conditions. The presence of cardiolipin antibodies is particularly significant in patients who have experienced unexplained venous or arterial thrombosis, thrombocytopenia (a condition characterized by low platelet counts), or fetal losses. The testing process typically involves an initial assessment, and if cardiolipin antibodies are detected, it is common practice to repeat the test approximately six weeks later. This follow-up is crucial to ascertain whether the antibodies are persistently present or merely a temporary finding, as low to moderate levels can sometimes occur due to infections or the influence of certain medications. In contrast, consistently elevated levels of these antibodies may suggest a more serious underlying issue, potentially contributing to the aforementioned conditions. Each class of cardiolipin antibody is reported separately, allowing for a detailed analysis of the patient's immune response.

The cardiolipin antibody test (CPT® Code 86147) is indicated for patients presenting with specific clinical conditions that may warrant further investigation into the presence of these antibodies. The following indications are explicitly recognized for this procedure:
The procedure for testing cardiolipin antibodies involves several key steps, which are outlined as follows:
After the cardiolipin antibody test is performed, patients may not require any specific post-procedure care. However, it is important for healthcare providers to communicate the results to the patient and discuss any necessary follow-up actions. If cardiolipin antibodies are detected, the provider may schedule a repeat test in about six weeks to determine if the antibodies are persistent. Patients should be informed about the potential implications of the test results, including the need for further evaluation or management of any underlying conditions related to thrombosis, thrombocytopenia, or fetal losses.

| 90 | Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number. | 91 | Repeat clinical diagnostic laboratory test: in the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. note: this modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. this modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). this modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient. | 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. | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | Q1 | Routine clinical service provided in a clinical research study that is in an approved clinical research study | 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 77 | Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | GA | Waiver of liability statement issued as required by payer policy, individual case | 32 | Mandated services: services related to mandated consultation and/or related services (eg, third party payer, governmental, legislative or regulatory requirement) may be identified by adding modifier 32 to the basic procedure. | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | GW | Service not related to the hospice patient's terminal condition | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | GZ | Item or service expected to be denied as not reasonable and necessary | X3 | Episodic/broad services: for reporting services by clinicians who have broad responsibility for the comprehensive needs of the patient that is limited to a defined period and circumstance such as a hospitalization; reporting clinician service examples include but are not limited to the hospitalist's services rendered providing comprehensive and general care to a patient while admitted to the hospital | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
