  • Use P36.8 for Other bacterial sepsis of newborn

  • Use P36.9 for Bacterial sepsis of newborn, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to P36: its own notes plus those printed at block P35-P39 and Chapter 16. A note printed at a category, block or chapter applies to every code under it.

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.
