Umbilical artery catheterization including obtaining of blood sample. This is listed as a major invasive procedure on page of the GP section and is therefore eligible for after-hours procedure premiums (E409, E410, E412, E413) when the service is non-elective or delayed by an emergency.

When to Use

Use G309 for the initial placement of an umbilical artery catheter in a newborn requiring intensive monitoring or frequent blood gas sampling.
Use G309 when the procedure is performed for emergency vascular access in a neonate, as it explicitly includes the collection of blood samples.

Common Pitfalls

Do not bill G309 in addition to G282 (Umbilical vein catheterization) if both are performed; the Ministry typically considers these part of the same procedural session or requires clear documentation of separate clinical necessity.
Avoid billing G309 for routine blood draws that do not involve the placement or maintenance of the catheter itself, as the code is specifically for the catheterization procedure.
Failure to document the 'non-elective' nature of the procedure will lead to the rejection of after-hours procedure premiums like E409 or E410.

Billing Tips

Since G309 is classified as a major invasive procedure, always append the appropriate after-hours premium (E409-E413) if the procedure meets the timing and urgency criteria.
Ensure the procedure start time is clearly documented in the chart to support the eligibility of the after-hours premium codes.
