CPT® Code 87184

The CPT® Code 87184 refers to susceptibility studies that assess the effectiveness of antimicrobial agents against specific bacteria using the disk method. This procedure involves placing a bacterial isolate on an agar plate, where it is then exposed to disks impregnated with various antibiotic agents. The primary goal of this study is to determine which antibiotics are effective in inhibiting the growth of the bacteria in question. The disk method is a widely used laboratory technique that allows for the evaluation of up to 12 different antimicrobial agents simultaneously on a single plate. By observing the zones of inhibition around each disk, laboratory personnel can identify the susceptibility or resistance of the bacteria to the tested antibiotics. This information is crucial for guiding appropriate antibiotic therapy in clinical settings, ensuring that patients receive the most effective treatment for their infections.
