CPT® Code 87582

The CPT® Code 87582 refers to a laboratory test designed for the detection of the infectious agent Mycoplasma pneumoniae through the analysis of nucleic acids, specifically DNA or RNA. Mycoplasma pneumoniae is classified as an atypical bacterium that is primarily transmitted via respiratory droplets. It is known to cause mild respiratory illnesses, which can manifest as pharyngitis, tracheobronchitis, or pneumonia, particularly in children and young adults. The test utilizes a direct probe method to identify a unique nucleic acid sequence, known as the target sequence, associated with the Mycoplasma pneumoniae organism, should it be present in a sample taken from respiratory or other bodily fluids. This process involves the use of a probe that is tagged with fluorescent or chemiluminescent markers. The sample undergoes treatment to release nucleic acids from the target organism, allowing the labeled probe to specifically bind to the matching target sequence, thereby forming a stable hybrid. Ribosomal RNA is often the focus of this detection method due to its abundance in microorganisms, as it is typically found in thousands of copies compared to the limited copies of genomic DNA. The assay's sensitivity is significantly enhanced through an amplified probe technique, which involves exponentially multiplying the target sequence of Mycoplasma pneumoniae DNA or RNA into millions of copies. The polymerase chain reaction (PCR) or reverse transcriptase polymerase chain reaction (RT-PCR) are the most frequently employed amplification techniques. Following amplification, the replicated sequences are identified using labeled DNA probes. The quantification aspect of this test, as indicated by CPT® Code 87582, provides a measurement of the number of microorganisms present in the sample. Quantitative or real-time PCR is often utilized to amplify the isolated nucleic acid segment, generating reports that document the absolute or relative amounts of the known nucleic acid sequence at each stage of the process.
