J301B – Simple Spirometry - Volume Versus Time Study - Technical Component
OHIP Cardio-Thoracic Surgery Code — Pulmonary Function Studies · Schedule of Benefits
This is the technical component of a simple spirometry Volume versus Time Study, claimed with suffix B. The study must include Vital capacity, , /FVC, and may include calculation of MMEFR(-75). The service may be delegated to a qualified employee in the physician's office as per the rules on page .
When to Use
- Use J301B when performing a basic volume-time spirometry study to assess obstructive or restrictive lung disease in a primary care setting.
- Use this code when the clinical requirement is specifically for FEV1, FVC, and FEV1/FVC ratios rather than the more detailed flow-volume loop data provided by J304B or J327B.
Common Pitfalls
- Billing J301B on the same day as J304B or J327B will result in an automatic rejection as they are mutually exclusive diagnostic procedures.
- Failing to document that the reported results represent the 'best of three' trials is a frequent cause for audit recovery, as this is a mandatory requirement for payment eligibility.
- Submitting the technical component for a hospital-based test without applying the mandatory 94.68% fee reduction will lead to billing discrepancies.
Billing Tips
- Ensure your office quality assurance log is current and explicitly references the calibration and maintenance of the spirometer to satisfy the MOH documentation requirement for delegated procedures.
