Intracranial hypotension following other procedure

This code signifies a condition where the pressure of the cerebrospinal fluid (CSF) within the skull is abnormally low, occurring as a complication of a medical procedure other than a lumbar puncture or spinal surgery. This can lead to symptoms such as orthostatic headache, nausea, dizziness, and visual disturbances due to the reduced buoyancy and support for the brain.

Apply this code when documentation clearly indicates intracranial hypotension developed after a procedure not specifically covered by codes for post-lumbar puncture or post-spinal surgery hypotension. Examples include hypotension following craniotomy, shunt placement, or other neurosurgical interventions where CSF leakage or altered CSF dynamics result in low intracranial pressure. Supporting documentation should detail the preceding procedure and the subsequent development of intracranial hypotension.

• Ensure the documentation specifies "intracranial hypotension" and links it directly to a non-spinal or non-lumbar puncture procedure.
• Do not confuse with G97.1 (Intracranial hypotension following lumbar puncture) or G97.0 (Intracranial hypotension following spinal surgery).
• Always sequence this code after the code for the underlying procedure or condition that led to the intracranial hypotension, if applicable.
