ICD-10-CM Code G01
Meningitis in bacterial diseases classified elsewhere
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.Manifestation Code
Certain ICD-10-CM codes identify an underlying condition known as an etiology code. Conditions that arise as a result of an underlying condition (etiology), are referred to as Manifestations. In ICD-10-CM, etiology codes must be coded first, followed by the manifestation codes. When a condition requires etiology and manifestation codes, there is a "use additional code" note following the etiology code and a "code first" note following the manifestation code.G01 is a billable ICD code used to specify a diagnosis of meningitis in bacterial diseases classified elsewhere. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code G01 is used to code Meningitis
Meningitis (from Greek μῆνιγξ méninx, "membrane" and the medical suffix -itis, "inflammation") is an acute inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges. The inflammation may be caused by infection with viruses, bacteria, or other microorganisms, and less commonly by certain drugs. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency.

Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here." - Meningitis (in):
- Gonococcal - instead, use code A54.81
- Leptospirosis - instead, use code A27.81
- Listeriosis - instead, use code A32.11
- Lyme disease - instead, use code A69.21
- Meningococcal - instead, use code A39.0
- Neurosyphilis - instead, use code A52.13
- Tuberculosis - instead, use code A17.0
- Meningoencephalitis and meningomyelitis in bacterial diseases classified elsewhere - instead, use Code G05

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 320.7 was previously used, G01 is the appropriate modern ICD10 code.
