Z412 – Replacement or repair of pacemaker lead
OHIP Psychiatric Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
Replacement or repair of pacemaker lead. This is a surgical procedure listed in the Cardiovascular Surgical Procedures section. The fee for this service has a surgical component (<suffix>A</suffix>), an assistant component (<suffix>B</suffix>), and an anaesthesia component (<suffix>C</suffix>). The assistant fee includes 6 basic units and the anaesthesia fee includes 7 basic units, plus applicable time units.
When to Use
- Use Z412 when performing a surgical revision or replacement of an existing pacemaker lead, distinct from the initial implantation procedure.
- Use this code for lead extraction or repositioning that requires a surgical incision and access to the lead system, rather than simple programming or non-invasive troubleshooting.
Common Pitfalls
- Billing Z412 in conjunction with Z415 (pacemaker generator change) without ensuring the clinical documentation clearly supports two distinct surgical procedures, as this may trigger a manual audit.
- Failing to append the correct suffix (A for surgeon, B for assistant, C for anaesthesia) will result in automatic claim rejection.
- Incorrectly billing Z412 when the service provided was merely a diagnostic check or non-surgical lead adjustment, which should be billed under non-surgical assessment codes.
Billing Tips
- Always verify if the procedure qualifies for age-based premiums (e.g., AGE_PREMIUM_UNDER_16_YEARS) based on the patient's exact age at the time of service to maximize the procedural fee.
- When billing for anaesthesia (suffix C), ensure that any applicable extra units for patient status or emergency surgery are submitted using the specific E-codes (e.g., E007C) to supplement the base 7 units.
