CPT® Code 87181

The CPT® Code 87181 refers to susceptibility studies that assess the effectiveness of specific antimicrobial agents, such as antibiotics, against particular bacteria. This testing is crucial in determining how well an antibiotic can inhibit or kill bacteria, which is essential for guiding appropriate treatment options for infections. The agar dilution method is employed in this procedure, where the bacteria are cultured in an agar solution that contains varying concentrations of the antibiotic. This method allows for a precise evaluation of the minimum inhibitory concentration (MIC) of the antibiotic, which is the lowest concentration that prevents visible growth of the bacteria. The results of this study help healthcare providers make informed decisions regarding antibiotic therapy, ensuring that the chosen antibiotic is effective against the identified bacterial strain. It is important to note that there are other related codes for different methods of susceptibility testing, each with specific applications and methodologies, which should be used accordingly based on the testing performed.
