The CPT® Code 82172 refers to the measurement of apolipoproteins, which are essential proteins that play a critical role in lipid metabolism. These proteins are composed of a protein molecule that is encased in lipids, allowing them to circulate effectively through the lymphatic and vascular systems without undergoing alteration. Specifically, Apolipoprotein-A is associated with high-density lipoproteins (HDL), while Apolipoprotein-B is linked to low-density lipoproteins (LDL). Both types of apolipoproteins are synthesized primarily in the liver and intestines. The measurement of these apolipoproteins is significant as it provides insight into an individual's risk for coronary artery disease (CAD) when expressed as a ratio. To obtain the necessary samples for testing, a fasting blood sample is collected through a procedure known as venipuncture, which is separately reportable. The analysis of the apolipoproteins is conducted using a method called quantitative nephelometry, which allows for precise measurement. If both Apolipoprotein-A and Apolipoprotein-B values are obtained, the code 82172 should be reported for the qualitative analysis of each apolipoprotein.

The measurement of apolipoproteins is indicated for assessing the risk of coronary artery disease (CAD) in patients. This test is particularly relevant for individuals who may have elevated cholesterol levels or other risk factors associated with cardiovascular diseases. The apolipoprotein levels can provide additional information beyond standard lipid panels, helping healthcare providers to evaluate a patient's lipid profile more comprehensively.
The procedure for measuring apolipoproteins involves several key steps that ensure accurate results. First, a fasting blood sample is obtained from the patient through venipuncture, which is a standard method for drawing blood. This step is crucial as fasting can influence the levels of lipids and apolipoproteins in the blood. Once the blood sample is collected, it is sent to a laboratory for analysis. The laboratory utilizes quantitative nephelometry, a technique that measures the concentration of proteins in the blood by assessing the light scattered by the particles in the sample. This method allows for precise quantification of both Apolipoprotein-A and Apolipoprotein-B. After obtaining the individual values for each apolipoprotein, a ratio can be calculated to provide further insight into the patient's risk for coronary artery disease. If both apolipoprotein values are measured, the appropriate CPT® code 82172 should be reported for the qualitative analysis.
After the procedure, patients may resume their normal activities immediately, as there are typically no significant post-procedure restrictions. However, it is essential for healthcare providers to inform patients about the importance of fasting prior to the blood draw to ensure accurate results. The results of the apolipoprotein tests will be reviewed by the healthcare provider, who will discuss the implications of the findings and any necessary follow-up actions or treatments based on the patient's overall health and risk factors for coronary artery disease.

| 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. | 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. | 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. | GA | Waiver of liability statement issued as required by payer policy, individual case | 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 | GW | Service not related to the hospice patient's terminal condition | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 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. | AY | Item or service furnished to an esrd patient that is not for the treatment of esrd | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | CR | Catastrophe/disaster related | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GX | Notice of liability issued, voluntary under payer policy | Q4 | Service for ordering/referring physician qualifies as a service exemption | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
