J307 – Functional residual capacity by body plethysmography
OHIP Cardio-Thoracic Surgery Code — PULMONARY FUNCTION STUDIES · Schedule of Benefits
J307 is a pulmonary function test to determine functional residual capacity using a body plethysmograph. This service is comprised of two distinct components that are claimed separately: a technical component (H Fee) and a professional component (P Fee). - Technical Component (H Fee): Covers the use of equipment, supplies, and personnel to perform the test. Per , the H fee is only payable when the service is rendered in a hospital setting and is subject to specific payment rules for hospital in-patients and out-patients who are subsequently admitted. - Professional Component (P Fee): Covers the physician's professional work, including the interpretation of the results and the generation of a report.
When to Use
- Use J307 when performing plethysmographic measurement of functional residual capacity to differentiate between obstructive and restrictive lung disease patterns.
- Select J307 over J311 when the clinical requirement specifically necessitates body plethysmography to measure lung volumes that cannot be accurately assessed via simple spirometry.
Common Pitfalls
- Claiming the H-fee for J307 in a private clinic setting, as the technical component is strictly restricted to hospital-based services.
- Submitting both J307 and J311 on the same service date, which will trigger an automatic rejection due to the explicit billing restriction between these pulmonary function studies.
Billing Tips
- Ensure the professional component (P-fee) is billed under the physician who interprets the plethysmography data and generates the formal diagnostic report.
