Code Classification

  • Diseases of the nervous system
    (G00–G99)

      (G89-G99)
      • Other disorders of central nervous system

G96.81 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of intracranial hypotension. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Intracranial hypotension

Non-specific codes like G96.81 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for intracranial hypotension:

  • Use G96.810 for Intracranial hypotension, unspecified - BILLABLE CODE

  • Use G96.811 for Intracranial hypotension, spontaneous - BILLABLE CODE

  • Use G96.819 for Other intracranial hypotension - BILLABLE CODE

Clinical Information

  • 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)
