N558 – Syringopleural/syringoperitoneal shunt
OHIP Otolaryngology Code — SPINAL SURGICAL PROCEDURES · Schedule of Benefits
Syringopleural/syringoperitoneal shunt is a surgical procedure involving neural elements to divert cerebrospinal fluid from a syrinx in the spinal cord to either the pleural space (around the lungs) or the peritoneal space (in the abdomen).
When to Use
- Use N558 for the surgical placement of a shunt to divert cerebrospinal fluid from a spinal syrinx to the pleural space.
- Use N558 for the surgical placement of a shunt to divert cerebrospinal fluid from a spinal syrinx to the peritoneal space.
Common Pitfalls
- Billing N558 in conjunction with any decompressive spinal procedure will result in a claim rejection, as the code is explicitly restricted from being rendered with any decompressive service.
- Failure to document the specific clinical indication for an acute spinal cord injury when attempting to bill the E383 premium will lead to audit recovery.
Billing Tips
- Ensure the E383 premium is only applied when the procedure is performed specifically for an acute spinal cord injury, as it is not applicable to elective syrinx shunting.
- Verify that the procedure is performed in a hospital setting to maintain eligibility for the E383 premium and standard surgical fee.
