2025 ICD-10-CM code G97.84
(Active) Effective Date: N/A Diseases of the nervous system - Other disorders of the nervous system 6 Feed
Intracranial hypotension following other procedure.
Medical necessity is established by the presence of signs and symptoms of intracranial hypotension following a medical procedure other than lumbar puncture or cerebrospinal fluid shunting. The documentation should support the diagnosis and link the condition to the preceding procedure.
Clinicians should document the causal relationship between the preceding procedure and the onset of intracranial hypotension. Detailed neurological examination findings, including orthostatic vital signs and symptom assessment, are essential.Imaging (MRI, CT myelogram) may be required to confirm the diagnosis and assess for underlying causes like cerebrospinal fluid leaks. Treatment is directed at the underlying cause and may include conservative measures like bed rest, hydration, caffeine administration, or epidural blood patches to seal any dural leaks.
In simple words: Low pressure inside the head (intracranial hypotension) occurring after a medical procedure, not including spinal taps or shunt procedures.
This code signifies a condition where the pressure within the skull is abnormally low, occurring as a complication after a medical procedure, excluding lumbar puncture or cerebrospinal fluid shunting.It is characterized by headaches, often worse when standing, and other neurological symptoms. The procedure causing the hypotension is not specified by this code itself.
Example 1: A patient develops orthostatic headaches and nausea following a hip replacement surgery. Imaging reveals a cerebrospinal fluid leak.G97.84 is coded as the hip replacement is the "other procedure" leading to the intracranial hypotension., Following a biopsy of a lung mass, a patient exhibits symptoms of intracranial hypotension, such as headaches, dizziness, and nausea. G97.84 is used due to the hypotension arising post-procedure., A patient undergoes a cardiac catheterization procedure. Several days later, they develop severe orthostatic headaches and other neurological symptoms consistent with intracranial hypotension. G97.84 is appropriate as the catheterization is the preceding "other procedure."
Documentation should clearly establish the temporal relationship between the "other procedure" and the onset of intracranial hypotension symptoms.Details of the prior procedure, neurological examination findings (including orthostatic hypotension signs), and results of any imaging studies (MRI, CT myelogram) should be included in the record.
