CPT® Code 87185

The CPT® Code 87185 refers to susceptibility studies that focus on the detection of enzymes produced by bacteria, specifically antimicrobial agents. This procedure is essential for determining the effectiveness of specific antibiotics against particular bacterial strains. The test is conducted in an agar solution, which serves as a medium for bacterial growth and interaction with the antibiotic. The primary aim of this study is to identify whether the bacteria produce enzymes, such as beta-lactamase, that can neutralize the effects of the antibiotic, thereby rendering it ineffective. This information is crucial for healthcare providers to select the appropriate antibiotic treatment for infections caused by resistant bacteria. The code is part of a broader set of susceptibility testing codes, each designated for different methodologies and purposes in evaluating bacterial resistance to antibiotics.
