Official Description

Lipoprotein, blood; electrophoretic separation and quantitation

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 83700 refers to a laboratory procedure known as lipoprotein electrophoresis, which is a blood test designed to measure the levels of lipoproteins in the bloodstream. Lipoproteins are complex biochemical structures that consist of lipid molecules, primarily fats, bound to proteins. These structures play a crucial role in the transport of lipids throughout the body via the circulatory system. Lipoproteins can vary significantly in size and density; they can be classified as large and less dense, where the fat content exceeds the protein content, or small and more dense, where the protein content surpasses the fat content. The origins of these lipoproteins can be either exogenous, derived from dietary fats, or endogenous, produced by the liver. To perform the test, a blood sample is collected through a procedure known as venipuncture, which is separately reportable. The process of electrophoresis involves applying an electrical field to the blood sample, which facilitates the separation of lipoprotein molecules based on their size and charge. Once separated, these lipoproteins are stained and quantified using a device called a densitometer, which measures the intensity of the stained bands corresponding to different lipoprotein fractions. This method provides valuable insights into the lipid profile of the patient, aiding in the assessment of cardiovascular health and the management of conditions related to lipid metabolism.

1. Indications

The lipoprotein electrophoresis test (CPT® Code 83700) is indicated for various clinical scenarios where assessment of lipid levels is necessary. The following conditions may warrant this procedure:

  • Assessment of Dyslipidemia - This test is performed to evaluate abnormal lipid levels in patients, which may include elevated cholesterol or triglyceride levels.
  • Cardiovascular Risk Evaluation - It is used to assess the risk of cardiovascular diseases, particularly in patients with a family history of heart disease or other risk factors.
  • Monitoring Lipid-Lowering Therapy - The procedure may be indicated for patients undergoing treatment for dyslipidemia to monitor the effectiveness of lipid-lowering medications.
  • Investigation of Pancreatitis - In cases of unexplained pancreatitis, this test can help identify elevated triglyceride levels that may contribute to the condition.

2. Procedure

The procedure for lipoprotein electrophoresis involves several key steps to ensure accurate measurement and analysis of lipoprotein levels in the blood. The following steps outline the process:

  • Step 1: Sample Collection - A blood sample is obtained from the patient through venipuncture, which involves inserting a needle into a vein to draw blood. This step is crucial as it provides the specimen needed for the electrophoresis test.
  • Step 2: Preparation of the Sample - Once the blood sample is collected, it is processed to separate the serum or plasma from the cellular components. This preparation is essential for accurate analysis of lipoproteins.
  • Step 3: Electrophoresis - The prepared sample is subjected to electrophoresis, where an electrical current is applied. This current causes the lipoprotein molecules to migrate through a gel matrix, separating them based on their size and charge.
  • Step 4: Staining - After separation, the lipoproteins are stained to visualize the distinct bands formed during electrophoresis. This staining process is critical for quantifying the lipoprotein fractions.
  • Step 5: Quantification - The stained bands are analyzed using a densitometer, which measures the intensity of each band. This quantification provides the levels of different lipoprotein types present in the sample.

3. Post-Procedure

After the lipoprotein electrophoresis procedure, the patient may experience minimal discomfort at the venipuncture site, which typically resolves quickly. There are no specific post-procedure care requirements, and patients can generally resume normal activities immediately. The results of the test are usually available within a few days, and healthcare providers will discuss the findings with the patient to determine any necessary follow-up actions or treatment adjustments based on the lipoprotein levels measured.

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.
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
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.
