Official Description

Electrophoretic technique, not elsewhere specified

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82664 refers to an electrophoretic technique that is not specified elsewhere in the coding system. This laboratory test employs electrophoresis, which is a sophisticated analytical method utilized for the separation and characterization of various molecules found in blood and other body fluids. Electrophoresis operates on the principle that charged particles will migrate in an electric field, allowing for the separation of these particles based on their size and electrical charge. As a result, this technique generates a distinct pattern of bands that vary in width and intensity, which can be analyzed to provide valuable diagnostic information. The code 82664 is particularly applicable for conducting a chylomicron screen of body fluids, where qualitative electrophoresis is used to assess the presence and characteristics of chylomicrons. Chylomicrons are small lipoprotein particles that play a crucial role in the transport of dietary fats, consisting of triglycerides, phospholipids, cholesterol, and proteins. This test is essential for understanding lipid metabolism and can aid in diagnosing various metabolic disorders.

1. Indications

The electrophoretic technique represented by CPT® Code 82664 is indicated for the analysis of specific molecules in blood and body fluids. The following conditions or symptoms may warrant the use of this procedure:

  • Assessment of Lipid Metabolism: This test is utilized to evaluate the presence and concentration of chylomicrons, which are essential for understanding lipid transport and metabolism in the body.
  • Investigation of Metabolic Disorders: The procedure can assist in diagnosing various metabolic disorders that may affect lipid levels and transport mechanisms.
  • Characterization of Proteins and Nucleic Acids: Electrophoresis can be used to separate and analyze proteins and nucleic acids, providing insights into various health conditions.

2. Procedure

The procedure for performing the electrophoretic technique under CPT® Code 82664 involves several key steps that ensure accurate separation and analysis of the sample. The following procedural steps are typically followed:

  • Sample Collection: A sample of blood or body fluid is collected from the patient, ensuring that proper collection techniques are followed to avoid contamination and ensure the integrity of the sample.
  • Preparation of the Sample: The collected sample is prepared for electrophoresis, which may involve dilution or the addition of specific reagents to facilitate the separation of molecules.
  • Electrophoresis Setup: The prepared sample is placed in an electrophoresis chamber, where an electric field is applied. This field causes the charged particles within the sample to migrate through a gel or other medium, separating them based on size and charge.
  • Visualization of Bands: After the electrophoresis run is complete, the separated molecules form distinct bands. These bands are visualized using staining techniques or other methods that allow for the assessment of their size and intensity.
  • Analysis and Interpretation: The resulting band patterns are analyzed by laboratory personnel, who interpret the results to provide diagnostic information regarding the presence of chylomicrons and other molecules of interest.

3. Post-Procedure

Post-procedure care following the electrophoretic technique under CPT® Code 82664 typically involves monitoring the patient for any immediate reactions to the sample collection. The results of the electrophoresis will be compiled and reported to the requesting physician, who will interpret the findings in the context of the patient's clinical picture. Patients may not require any specific recovery time, as this is a laboratory test rather than an invasive procedure. However, it is essential for healthcare providers to ensure that patients are informed about when they can expect to receive their results and any follow-up actions that may be necessary based on those results.

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.
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.
