This procedure involves the surgical placement of an intraperitoneal chemotherapy port, which can be performed through either an open abdominal incision (laparotomy) or via a minimally invasive technique (laparoscopy).

When to Use

Use S310 as the primary procedure code when the sole clinical objective is the surgical placement of an intraperitoneal chemotherapy port.
Select S310 when the procedure is performed as a standalone intervention, regardless of whether the surgical approach is via laparotomy or laparoscopy.

Common Pitfalls

Billing S310 in conjunction with any other open or laparoscopic abdominal procedure will result in an automatic rejection, as the fee is considered inclusive of the abdominal access.
Attempting to bill S310 alongside S315 is prohibited, as these codes are mutually exclusive and represent the same clinical intent for port placement.
Failing to account for the 'inclusive' nature of the code; if the port is placed during a larger abdominal surgery, the port placement is considered part of the primary procedure and S310 is not separately payable.

Billing Tips

If the procedure is performed on an urgent or emergent basis outside of standard operating hours, ensure you append the appropriate after-hours premium (E409A or E410A) to maximize the claim value.
Always verify that no other abdominal surgical procedure codes are submitted on the same claim date, as the Ministry of Health considers S310 bundled into any other abdominal surgery.
