CPT® Code 87190

The CPT® Code 87190 refers to susceptibility studies specifically designed to evaluate the effectiveness of antimicrobial agents against mycobacteria, which are a type of bacteria that includes pathogens such as those responsible for tuberculosis. This procedure employs the proportion method, a laboratory technique that assesses how well various antibiotics can inhibit the growth of mycobacteria. The test is conducted in an agar solution, which serves as a growth medium for the bacteria. By determining the susceptibility of mycobacteria to specific antibiotics, healthcare providers can make informed decisions regarding the most effective treatment options for infections caused by these organisms. This code is particularly relevant in the context of antibiotic resistance, as it helps identify which antibiotics remain effective against resistant strains of mycobacteria. It is important to note that other related codes exist for different testing methods and types of bacteria, each serving a unique purpose in the assessment of antimicrobial susceptibility.
