This service covers the second or any subsequent surgical stage required for the complete repair of an omphalocele or gastroschisis. This procedure is typically part of a multi-stage approach to correcting these complex congenital abdominal wall defects. See also S348 for primary or first stage repair. This is a surgical procedure and is eligible for surgeon (A), assistant (B), and anaesthetist (C) services. Assistant services are paid based on 7 base units plus time units. Anaesthesia services are paid based on 7 base units plus time units. See - for assistant rules and - for anaesthesia rules.

When to Use

Use for the secondary closure of a gastroschisis defect following the initial reduction or silo placement performed under S348.
Use for subsequent surgical revisions or definitive abdominal wall reconstruction required after the initial primary repair of an omphalocele.
Use for staged procedures where the abdominal wall defect cannot be closed primarily in a single operative session.

Common Pitfalls

Billing S349 for the initial primary repair, which must be billed exclusively as S348.
Failing to include the appropriate age-based fee premium, as these patients are almost exclusively neonates or infants eligible for the 30% (under 30 days) or 25% (under 1 year) premiums.
Omitting the required anaesthesia extra units (E014C or E009C) when billing for the anaesthesiologist's portion of the procedure.

Billing Tips

Ensure the operative report clearly distinguishes the stage of the repair to justify the use of S349 over the primary S348 code.
Verify that the surgical assistant and anaesthesiologist have applied the correct base units (7) plus time units, as these are distinct from standard surgical fee calculations.
