Intracranial and intraspinal abscess and granuloma in diseases classified elsewhere (G07)

The ICD-10 code G07 is used for coding intracranial and intraspinal abscesses and granulomas that occur as complications of other diseases. This code specifically covers infections in the central nervous system (CNS) leading to abscess formation or granuloma development.

This code includes conditions often referred to as CNS abscess and covers various forms of granulomas related to schistosomal infections. Synonyms such as Schistosomal granuloma of central nervous system, Otogenic intracranial abscess, and granulomas caused by different species of Schistosoma (including Schistosoma japonicum, Schistosoma haematobium, and Schistosoma mansoni) are all classified under G07. Medical coders will use this code when an intracranial or intraspinal abscess or granuloma is known to stem from a primary disease elsewhere, providing clarity for diagnosis and billing in such complex cases. The ICD-10 code G07 thus helps accurately capture and differentiate these brain and spinal infections associated with broader systemic diseases.

Instructional Notations

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, such as:
  • schistosomiasis granuloma of brain B65

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.
