What ESBL ICD-10 codes can I use?
If you're looking for ESBL ICD codes, please note that there is only one ICD-10 code that specifically mentions ESBL in its name: Z16.12 - Extended spectrum beta lactamase (ESBL) resistance.
This ICD-10 code is meant to be used on a patient confirmed to have been infected with bacteria that produce extended spectrum beta lactamase. ESBL can make the bacteria that produce it more resistant to antibiotics.
Use this ICD-10 code if your patient has bacteria that can fight off the effects of antibiotics due to ESBL.
One thing to note about this code is that it's considered unacceptable as a principal diagnosis since it's meant to explain that there is resistance to antibiotics due to bacteria with ESBL.
The main ICD-10 code you need to use should be for designating a bacterial infection. The closest ICD-10 you can use for that is A49.8 - Other bacterial infections of unspecified site, because there are no specific ICD-10 codes that specify ESBL bacterial infection.
