About B96.2
B96.2 is the ICD-10-CM diagnosis code for escherichia coli [E. coli ] as the cause of diseases classified elsewhere. It belongs to category B96 (other bacterial agents as the cause of diseases classified elsewhere), block B95-B97 (bacterial and viral infectious agents) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.
Within B96 (other bacterial agents as the cause of diseases classified elsewhere), B96.2 is specifically for escherichia coli [E. coli ] as the cause of diseases classified elsewhere. Related codes cover mycoplasma pneumoniae [M. pneumoniae] as the cause of diseases classified elsewhere (B96.0), Klebsiella pneumoniae [K. pneumoniae] as the cause of diseases classified elsewhere (B96.1), hemophilus influenzae [H. influenzae] as the cause of diseases classified elsewhere (B96.3), proteus (mirabilis) (morganii) as the cause of diseases classified elsewhere (B96.4), pseudomonas (aeruginosa) (mallei) (pseudomallei) as the cause of diseases classified elsewhere (B96.5), Bacteroides fragilis [B. fragilis] as the cause of diseases classified elsewhere (B96.6), Clostridium perfringens [C. perfringens] as the cause of diseases classified elsewhere (B96.7) and other specified bacterial agents as the cause of diseases classified elsewhere (B96.8).
