Infection with microorganisms resistant to tetracyclines

This code indicates a bacterial infection where the causative microorganism has developed resistance to tetracycline antibiotics. This resistance means that treatment with tetracyclines would likely be ineffective, necessitating alternative antibiotic therapies. It signifies a challenge in managing the infection due to the limited efficacy of a common antibiotic class.

Use this code when documentation explicitly states an infection is caused by a microorganism identified as resistant to tetracyclines. This often follows laboratory culture and sensitivity testing that confirms tetracycline resistance. It is appropriate for conditions such as resistant urinary tract infections, respiratory infections, or skin and soft tissue infections.

• Ensure documentation clearly specifies both the infection and the microorganism's resistance to tetracyclines.
• Do not use this code if the resistance is to an antibiotic other than tetracycline.
• Always code the underlying infection first, followed by this resistance code as a secondary diagnosis.
