Questions About G97Overview

Is G97 a billable code?

No. This is a category header that groups the codes for intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified, and headers cannot be submitted on claims. Claims for intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified need a more specific code from this category, such as G97.0, G97.1, and G97.2.
