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

The ICD-10 code section G97 covers intraoperative and postprocedural complications involving the nervous system that are not classified elsewhere. These codes capture specific nervous system issues arising during or after medical procedures, such as cerebrospinal fluid leaks, hemorrhages, accidental punctures, and intracranial hypotension.

This group includes codes like G97.0 for cerebrospinal fluid leaks from spinal punctures, often referred to as cranial cerebrospinal fluid leaks, and G97.1 for complications like post dural puncture headaches or intracranial hypotension following lumbar punctures. Other codes such as G97.3 and its subsets address intraoperative hemorrhage and hematoma complications affecting nervous system structures during surgeries. Codes like G97.41 specify accidental punctures of the dura during procedures, known sometimes as inadvertent dural taps. Postprocedural hemorrhages and hematomas also have detailed codes, including G97.51 and G97.61. Additionally, G97.8 covers other nervous system complications such as nerve injury during surgery or postoperative meningitis. For medical coders seeking the ICD-10 code for conditions like neurological disorder due to lumbar puncture or postoperative cerebrospinal fluid leaks, these G97 codes provide precise classification for postprocedural nervous system complications.

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.

  • intraoperative and postprocedural cerebrovascular infarction I97.81 I97.82

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

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)
