Infection with microorganisms resistant to macrolides

This diagnosis code signifies an infection caused by bacteria that have developed resistance to macrolide antibiotics. These antibiotics, such as azithromycin, clarithromycin, and erythromycin, are commonly used to treat various bacterial infections, particularly respiratory and skin infections. The resistance means that these standard treatments are ineffective against the identified pathogen.

Assign this code when laboratory testing confirms a bacterial infection and susceptibility testing demonstrates resistance to macrolide antibiotics. This is typically used when a patient presents with an infection that is not responding to macrolide therapy, or when initial culture and sensitivity results indicate macrolide resistance. It's crucial for documenting the need for alternative antibiotic regimens.

• Ensure documentation clearly states both the infection and the specific resistance to macrolides.
• This code is for resistance to the class of macrolide antibiotics, not a single drug.
• Always sequence this code after the primary infection code, if applicable, to provide specificity about the pathogen's characteristics.
