OHIP Cardio-Thoracic Surgery Code — Pulmonary Function Studies · Schedule of Benefits
This is the professional component of a simple spirometry Volume versus Time Study, claimed with suffix C. The study must include Vital capacity, , /FVC, and may include calculation of MMEFR(-75). The service covers the physician's written interpretation of the test results. Per the General Preamble on page , the professional component of a diagnostic service is claimed using suffix 'C'.
When to Use
- Use J301C when performing a professional interpretation of a simple volume-time spirometry study to assess obstructive or restrictive lung disease.
- Use this code specifically when the clinical requirement is limited to FEV1, FVC, and FEV1/FVC ratios, rather than the more comprehensive flow-volume loop analysis required by J304C.
Common Pitfalls
- Claiming J301C on the same day as J304C or J327C will result in an automatic rejection due to the restriction on concurrent flow-volume loop studies.
- Failing to document that the reported values represent the best of three maneuvers is a frequent cause for audit recovery, as this is a mandatory requirement for payment.
Billing Tips
- Ensure your written interpretation is physically attached to or clearly linked with the permanent spirometry tracing in the patient record to satisfy the documentation requirement for the professional component.
