ICD-10 Code G97.2 – Intracranial hypotension following ventricular shunting (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G97.2 – Intracranial hypotension following ventricular shunting
What it is
This code identifies low intracranial pressure that occurs after a ventricular shunt procedure. It reflects a postprocedural complication, not the underlying hydrocephalus or the shunt device itself.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include postural headache, nausea, vomiting, or other symptoms linked to low cerebrospinal fluid pressure after shunting.
When to use this code
Use G97.2 when the record clearly documents intracranial hypotension as a complication of ventricular shunting. Apply it for postoperative or follow-up encounters where the provider links symptoms or imaging findings to the shunt procedure. If the note only mentions shunt adjustment, malfunction, or hydrocephalus without hypotension, check documentation.
Do not use for
Do not use this code for intracranial hypotension from nonshunt causes or for unspecified headache after surgery. Also avoid it when the provider documents shunt malfunction, infection, or obstruction without stating hypotension.
Coding tip
Code the complication only when the provider explicitly connects the low-pressure state to ventricular shunting.
