When to Use

Use N245 for the surgical revision of an existing cerebrospinal fluid (CSF) shunt, such as a ventriculoperitoneal (VP) or ventriculoatrial (VA) shunt, when the procedure involves hardware adjustment, replacement, or repair.
Select N245 when the primary clinical intent is the restoration of shunt function due to obstruction, migration, or mechanical failure, distinguishing it from initial shunt insertion codes.

Common Pitfalls

Billing N245 alongside other neurosurgical procedures performed during the same operative session without checking for Schedule of Benefits 'multiple procedure' rules, which may trigger automatic reductions.
Failure to document the Injury Severity Score (ISS) in the medical record when attempting to claim the E420 trauma premium, leading to inevitable audit recovery.
Incorrectly applying after-hours premiums (E409/E410) to elective revisions; these premiums are strictly reserved for non-elective cases or those delayed by an intervening surgical emergency.

Billing Tips

Ensure the operative report explicitly details the revision performed, as this documentation is the primary defense against claims that the procedure was a minor adjustment rather than a full surgical revision.
When billing for surgical assistants or anaesthetists, verify that the basic units claimed align with the major procedure identified in the operative note to avoid discrepancies during the adjudication process.
