Resistance to quinolones and fluoroquinolones

This code indicates that a bacterial pathogen has developed resistance to quinolone and fluoroquinolone antibiotics, rendering these drugs ineffective for treatment. This resistance can be identified through laboratory susceptibility testing of an isolated pathogen. It signifies a significant challenge in treating infections caused by such resistant organisms.

Use this code when a patient's infection is confirmed to be caused by a bacterium resistant to quinolone and fluoroquinolone antibiotics, typically documented by culture and sensitivity results. This applies when the resistance impacts treatment decisions, requiring the use of alternative antibiotic classes. It's crucial for tracking antimicrobial resistance patterns and guiding appropriate therapy.

• Always link this resistance code to the specific infection code (e.g., pneumonia, UTI) for which the resistance was identified.
• Ensure documentation clearly states the pathogen's resistance to quinolones/fluoroquinolones, often from microbiology reports.
• Do not use this code if resistance is merely suspected or if the patient has a history of quinolone allergy without confirmed pathogen resistance.
