About G97
G97 is the ICD-10-CM diagnosis code for intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified. It belongs to block G89-G99 (other disorders of the 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 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: G97.0 (puncture), G97.1 (puncture), G97.2 (shunting), G97.3 (procedure), G97.4 (procedure), G97.5 (procedure), G97.6 (procedure) and G97.8 (system).
The conditions in its Excludes2 note aren't part of G97, but may be coded alongside it if the patient has both: intraoperative and postprocedural cerebrovascular infarction (I97.81-, I97.82-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
