G308 – Pacemaker pulse wave analysis - technical component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Represents the technical component of a pacemaker pulse wave analysis, including electrocardiography. This fee covers the use of equipment, supplies, and personnel for the procedure. The professional component for interpretation is billed separately as G307. Payment for this service is subject to specific rules when rendered in a hospital setting.
When to Use
- Use G308 to bill for the technical component of pacemaker pulse wave analysis performed in a community clinic setting.
- Use G308 in conjunction with G307 when you are the physician responsible for both the technical equipment/personnel and the professional interpretation of the analysis.
Common Pitfalls
- Billing G308 for a patient who is currently admitted as an in-patient in a hospital will result in a mandatory rejection.
- Failing to account for the 5.32% reduction when billing G308A for services rendered within a hospital facility, as per the technical component adjustment rules.
- Submitting G308 without a valid referral from a physician or nurse practitioner, which is a mandatory requirement under GP111.
Billing Tips
- Always bill G308 alongside G307 to ensure you are capturing both the technical and professional components of the pacemaker analysis.
