Extensively drug-resistant mycobacterium tuberculosis

Description

Extensively drug-resistant tuberculous mycobacteria are resistant to at least four of the core anti-TB drugs. XDR-TB mycobacteria are resistant to the two most powerful anti-TB drugs, isoniazid and rifampicin, also known as multidrug-resistance, in addition to resistance to any of the fluoroquinolones (such as levofloxacin or moxifloxacin) and to at least one of the three injectable second-line drugs (amikacin, capreomycin or kanamycin).

Coding note

These categories should never be used in primary coding. The codes are provided for use as supplementary or additional codes when it is desired to identify the resistance, non-responsiveness and refractive properties of a condition to antimicrobials.

Coding note from above levels

These categories should never be used in primary coding. The codes are provided for use as supplementary or additional codes when it is desired to identify the resistance, non-responsiveness and refractive properties of a condition to antimicrobials. In case of multiple resistances, code each one separately if listed below.
