The CPT® Code 84702 refers to the quantitative measurement of chorionic gonadotropin (hCG) in a specimen, typically blood. This procedure involves obtaining a blood sample through a process known as venipuncture, which is separately reportable. The quantitative analysis specifically measures the concentration of hCG present in the blood, providing critical information for various clinical scenarios. The presence and levels of hCG are significant in diagnosing conditions such as ectopic pregnancy, where the embryo implants outside the uterus, and in monitoring pregnancies that may be at risk for complications like threatened or missed abortion. Additionally, this test is utilized following a spontaneous abortion to assess hCG levels. Beyond pregnancy-related conditions, the quantitative hCG test is also instrumental in diagnosing trophoblastic diseases, such as hydatidiform mole, and in evaluating germ cell tumors of the testes or ovaries. Furthermore, it plays a role in monitoring the effectiveness of treatment for these conditions and in identifying any potential recurrence. In contrast, the CPT® Code 84703 pertains to a qualitative test that only determines the presence or absence of hCG, which can be performed on either blood or urine samples and is primarily used to confirm pregnancy.

The quantitative measurement of chorionic gonadotropin (hCG) using CPT® Code 84702 is indicated for several clinical scenarios, including:
The procedure for obtaining a quantitative measurement of hCG involves several key steps:
After the procedure, patients may experience minor discomfort or bruising at the venipuncture site, which typically resolves quickly. There are no specific post-procedure care instructions required for the hCG test; however, patients should be advised to contact their healthcare provider if they experience excessive bleeding, swelling, or signs of infection at the site. The results of the hCG test will be discussed with the patient during a follow-up appointment, where the healthcare provider will explain the implications of the findings and any necessary next steps in management or treatment.

| GA | Waiver of liability statement issued as required by payer policy, individual case | GZ | Item or service expected to be denied as not reasonable and necessary | 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. | Q4 | Service for ordering/referring physician qualifies as a service exemption | Q1 | Routine clinical service provided in a clinical research study that is in an approved clinical research study | 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. | 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 | 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. | 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. | CR | Catastrophe/disaster related | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GW | Service not related to the hospice patient's terminal condition | GX | Notice of liability issued, voluntary under payer policy |
