Intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified (G97) ICD-10-CM
The G97 code range covers intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified with 24 ICD-10-CM diagnosis codes. 18 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the G97 Code Range
These conditions affect the nervous system during a procedure or afterward. They include puncture reactions, bleeding, accidental injury, and fluid collections.
G97.0 identifies a spinal fluid leak after spinal puncture; G97.1 identifies other reactions to spinal or lumbar puncture. G97.2 identifies low pressure inside the skull after ventricular shunting.
G97.3 separates bleeding during a procedure by whether it is a nervous system procedure. G97.4 distinguishes accidental injury to the dura from injury to other nervous system structures. G97.5 and G97.6 distinguish bleeding from blood or other fluid collections after a procedure, with further splits by procedure type.
G97.8 includes other complications during or after procedures, including low pressure inside the skull after lumbar fluid shunting or another procedure.
