Official Description

Array-based evaluation of multiple molecular probes; 251 through 500 probes

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 88386 refers to an array-based evaluation of multiple molecular probes, specifically when the number of probes utilized ranges from 251 to 500. This procedure involves the use of specialized instruments designed to analyze nucleic acid molecules, which are essential components of genetic material. The evaluation is performed to detect specific genetic sequences or alterations that may be relevant in various clinical contexts, such as diagnosing diseases, understanding genetic predispositions, or guiding treatment decisions. The process is highly technical and requires precise handling of the probes to ensure accurate results. It is important to note that different codes are designated for varying numbers of probes: for instance, if the evaluation involves between 11 and 50 probes, CPT® Code 88384 is applicable, while for 51 to 250 probes, CPT® Code 88385 should be reported. The distinction in coding based on the number of probes reflects the complexity and scope of the evaluation being performed.

1. Indications

The procedure associated with CPT® Code 88386 is indicated for the evaluation of nucleic acid molecules when a comprehensive analysis involving a larger number of molecular probes is required. This may include, but is not limited to, the following conditions:

  • Genetic Testing The procedure is utilized to identify genetic mutations or variations that may contribute to hereditary diseases or conditions.
  • Oncology It is often indicated in cancer diagnostics to assess genetic alterations that may influence tumor behavior or treatment response.
  • Infectious Disease The evaluation can be used to detect specific pathogens or genetic markers associated with infectious diseases.

2. Procedure

The procedure for CPT® Code 88386 involves several key steps that ensure the accurate evaluation of nucleic acid molecules using a high number of molecular probes. Each step is critical to the overall success of the analysis:

  • Step 1: Sample Preparation The first step involves the collection and preparation of the biological sample, which may include blood, tissue, or other specimens containing nucleic acids. The sample is processed to extract the nucleic acids, ensuring that they are suitable for analysis.
  • Step 2: Probe Selection Following sample preparation, a selection of 251 to 500 specific molecular probes is chosen based on the target sequences of interest. These probes are designed to hybridize with complementary nucleic acid sequences in the sample, allowing for the detection of specific genetic information.
  • Step 3: Hybridization The selected probes are then applied to the prepared sample in a controlled environment, where they hybridize with the target nucleic acids. This step is crucial as it determines the specificity and sensitivity of the evaluation.
  • Step 4: Detection and Analysis After hybridization, the bound probes are detected using specialized instruments that can quantify the signals generated. This data is then analyzed to identify the presence or absence of specific genetic sequences, providing valuable insights into the sample's genetic makeup.

3. Post-Procedure

Post-procedure care for CPT® Code 88386 typically involves the interpretation of the results obtained from the array-based evaluation. Healthcare professionals must review the findings in conjunction with clinical information to make informed decisions regarding diagnosis and treatment. Additionally, it is essential to document the results accurately and communicate them to the relevant healthcare providers. Follow-up may be necessary to discuss the implications of the findings with the patient and to determine any further testing or treatment options that may be required based on the results of the evaluation.
