- Section I.C.1.b Infectious agents as the cause of diseases classified to other chapters (page 22), covers B95-B97
When an infection coded outside Chapter 1 does not name the organism, add a code from category B95, B96, or B97 to identify it.
Other Chapter 1 topics:
- Human Immunodeficiency Virus (HIV) Infections (page 19)
- Infections resistant to antibiotics (page 22)
- Sepsis, Severe Sepsis, and Septic Shock (page 23)
- Methicillin Resistant Staphylococcus aureus (MRSA) Conditions (page 27)
- Zika virus infections (page 28)
- Coronavirus infections (page 28)

Bacterial Infections
Bacteria are tiny organisms (living things) that have only one cell. Under a microscope, they look like balls, rods, or spirals. They can be found almost everywhere on Earth. There are lots of bacteria in and on your body. In fact, your body has about 10 times more bacteria cells than human cells.

Staphylococcus (staph) is a group of bacteria. There are more than 30 types. A type called Staphylococcus aureus causes most infections. Staph bacteria can cause many different types of infections, including:
