Bacterial meningitis, not elsewhere classified (G00)
ICD-10 code section G00 covers various types of bacterial meningitis that are not classified under other specific categories. These codes are used to accurately identify and document bacterial infections causing inflammation of the membranes around the brain and spinal cord.
This section includes precise codes for infections caused by different bacteria: G00.0 specifies Haemophilus meningitis (also known as Haemophilus influenzae meningitis or infection of the central nervous system by Haemophilus), G00.1 is for pneumococcal meningitis (caused by Streptococcus pneumoniae), G00.2 covers streptococcal meningitis including infections from various Streptococcus species, and G00.3 identifies staphylococcal meningitis, including infections by Staphylococcus aureus and coagulase-negative staphylococci. The G00.8 code is reserved for other bacterial meningitis caused by less common bacteria such as Klebsiella, Pseudomonas, or Escherichia coli. When the specific bacteria is unknown, G00.9 is used to indicate bacterial meningitis, unspecified.
Medical coders rely on these codes to capture the exact bacterial cause of meningitis, aiding in clinical documentation and appropriate treatment tracking. Understanding the synonyms like “acute purulent meningitis” or “infective meningitis” helps link clinical terms with the ICD-10 coding system efficiently. The ICD-10 code for bacterial meningitis assists healthcare professionals in distinguishing between different bacterial pathogens responsible for central nervous system infections.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
