About G06

G06 is the ICD-10-CM diagnosis code for intracranial and intraspinal abscess and granuloma. It belongs to block G00-G09 (inflammatory diseases of the central nervous system) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: G06.0 (granuloma), G06.1 (granuloma) and G06.2 (unspecified).

Use an additional code (B95-B97) to identify infectious agent.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
