J313C – Mixed Venous Pco2, by the Rebreathing Method - Professional Component
OHIP Cardio-Thoracic Surgery Code — Diagnostic and Therapeutic Procedures · Schedule of Benefits
This code represents the professional component ('P' Fee) for the measurement of mixed venous by the rebreathing method. The professional component is for the interpretation of the results and the provision of a report of the findings.
When to Use
- Use J313C when performing the professional interpretation of a rebreathing study to estimate mixed venous PCO2 in patients with suspected pulmonary hypertension or heart failure.
- Select this code when you are specifically billing for the physician's review and formal report of the rebreathing data, distinct from the technical component of the test.
Common Pitfalls
- Billing J313C alongside a comprehensive pulmonary function test (e.g., G399) without clear clinical justification for both, which may trigger a duplicate service audit.
- Submitting J313C without a corresponding formal, signed interpretation report in the patient chart, as the professional component fee is contingent upon this documentation.
Billing Tips
- Ensure the technical component of the test is billed separately by the facility or lab, as J313C only covers the professional interpretation fee.
- Verify that the rebreathing method is explicitly documented in the report to distinguish this specific diagnostic procedure from standard arterial blood gas analysis (G394).
