Intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified (G97)

Browse all the diagnosis codes used for intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified (g97). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Cerebrospinal Fluid Otorrhea - Discharge of cerebrospinal fluid through the external auditory meatus or through the eustachian tube into the nasopharynx. This is usually associated with CRANIOCEREBRAL TRAUMA (e.g., SKULL FRACTURE involving the TEMPORAL BONE;), NEUROSURGICAL PROCEDURES; or other conditions, but may rarely occur spontaneously. (From Am J Otol 1995 Nov;16(6):765-71)

Intracranial Hypotension - Reduction of CEREBROSPINAL FLUID pressure characterized clinically by ORTHOSTATIC HEADACHE and occasionally by an ABDUCENS NERVE PALSY; HEARING LOSS; NAUSEA; neck stiffness, and other symptoms. This condition may be spontaneous or secondary to CEREBROSPINAL FLUID LEAK; SPINAL PUNCTURE; NEUROSURGICAL PROCEDURES; DEHYDRATION; UREMIA; trauma (see also CRANIOCEREBRAL TRAUMA); and other processes. Chronic hypotension may be associated with subdural hematomas (see HEMATOMA, SUBDURAL) or hygromas. (From Semin Neurol 1996 Mar;16(1):5-10; Adams et al., Principles of Neurology, 6th ed, pp637-8)

Instructional Notations

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.
