About the B95–B97 Code Range
These codes identify bacteria and viruses named as the cause of diseases classified elsewhere. They identify the infectious agent rather than the disease it causes.
B95 groups Streptococcus, Staphylococcus and Enterococcus, with subdivisions for named organisms and, where listed, groups or unspecified organisms. B96 identifies other bacterial agents, such as E. coli and Pseudomonas. B97 separates viral agents by type, including adenovirus, coronavirus and respiratory syncytial virus.
