Meningitis in bacterial diseases classified elsewhere (G01) ICD-10-CM
The G01 code range covers meningitis in bacterial diseases classified elsewhere with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- underlying disease
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.

About the G01 Code Range
This section covers the ICD-10 code G01, used specifically for meningitis linked to bacterial infections classified in other parts of the ICD system. It identifies cases where meningitis arises from bacteria like Nocardia, rather than primary meningitis codes.
The code G01 helps medical coders and healthcare providers accurately classify meningitis that occurs as a complication of bacterial diseases found elsewhere in the body. This includes conditions sometimes called meningitis caused by Nocardia, a rare but important type of bacterial meningitis. Using the ICD-10 code for meningitis in bacterial diseases classified elsewhere ensures precise documentation and improves clarity in patient records when the infectious bacteria are not primarily meningitis agents but still cause inflammation of the meninges. This distinction supports better diagnosis, treatment decisions, and health data tracking by connecting the meningitis to its bacterial origin.
