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.

  • What are the treatments for bacterial infections?
  • Can bacterial infections be prevented?

Questions About B96Overview

Is B96 a billable code?

No. This is a category header that groups the codes for other bacterial agents as the cause of diseases classified elsewhere, and headers cannot be submitted on claims. Claims for other bacterial agents as the cause of diseases classified elsewhere need a more specific code from this category, such as B96.0, B96.1, and B96.20.
