Z429 – Implantation of coronary sinus lead for biventricular pacing
OHIP Psychiatric Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
Implantation of a coronary sinus lead for biventricular pacing. This is a surgical procedure listed in the Cardiovascular Surgical Procedures section of the Schedule of Benefits. Payment is available for the surgeon (A suffix), surgical assistant (B suffix), and anaesthetist (C suffix). The fees for the assistant and anaesthetist are calculated based on basic units plus time units as described in to and to .
When to Use
- Use Z429 specifically for the implantation of a coronary sinus lead during a biventricular pacing procedure (CRT-D or CRT-P).
- Do not use this code for standard right atrial or right ventricular lead placement; those are billed under separate cardiovascular surgical codes.
Common Pitfalls
- Billing Z429 as a standalone procedure when it is performed as part of a larger system implantation; ensure the claim reflects the full scope of the surgical session.
- Failing to include the necessary surgical assistant or anaesthetist suffixes (B or C) when the procedure is performed by a team, as these are not automatically generated.
Billing Tips
- Ensure that if the procedure is performed after hours, the appropriate E-series premium (E409 or E410) is linked to the Z429 claim to capture the 50% or 75% increase.
