CPT® Code 83891

Deleted

1. Indications

Molecular diagnostics using CPT® Code 83891 are indicated for a variety of clinical scenarios, including but not limited to the following:

• Genetic Mutation Detection Molecular diagnostic tests are performed to identify genetic mutations that may be associated with specific diseases, even in asymptomatic patients.
• Monitoring Disease States These tests can be utilized to monitor the progression of current disease states, providing valuable information for treatment decisions.
• Diagnosis of Conditions Molecular diagnostics assist in the diagnosis of certain conditions by analyzing genetic material.
• Carrier Screening The tests are used to screen for individuals who may be carriers of genetic diseases, which is crucial for family planning and preventive care.
• Predisposition Assessment Individuals who are predisposed to certain conditions may undergo these tests to determine their risk and need for preventive medical interventions.

2. Procedure

The procedure for CPT® Code 83891 involves several key steps to ensure the successful isolation or extraction of highly purified nucleic acids. Each step is critical to the integrity and quality of the nucleic acid being prepared for analysis.

• Step 1: Sample Collection The process begins with the collection of a biological sample, which may include blood, tissue, or other bodily fluids. The choice of sample type is determined by the specific diagnostic requirements and the nucleic acid to be analyzed.
• Step 2: Nucleic Acid Preparation Following sample collection, the nucleic acids (DNA or RNA) are prepared for isolation. This may involve the use of various reagents and techniques to break down cellular components and release the nucleic acids into solution.
• Step 3: Isolation or Extraction The actual isolation or extraction of the nucleic acids is performed using techniques such as precipitation, chromatography, or centrifugation. These methods are selected based on the type of nucleic acid being extracted and the desired purity level.
• Step 4: Purification Once the nucleic acids are isolated, further purification steps may be employed to remove contaminants and ensure that the nucleic acids are highly purified. This is essential for accurate downstream applications, such as sequencing or amplification.
• Step 5: Quality Control After purification, quality control measures are taken to assess the integrity and concentration of the isolated nucleic acids. This may involve spectrophotometric analysis or gel electrophoresis to confirm that the nucleic acids meet the required standards for testing.

3. Post-Procedure

Post-procedure care for CPT® Code 83891 primarily involves the handling and storage of the isolated nucleic acids. It is essential to store the purified nucleic acids under appropriate conditions to maintain their stability and integrity for future analysis. Additionally, documentation of the extraction process, including any quality control results, is crucial for compliance and traceability. The results obtained from the molecular diagnostic tests can then be utilized for further clinical decision-making, including treatment planning and patient management.
