J804
J804 – First transit - without blood pool images
OHIP Cardio-Thoracic Surgery Code · Schedule of Benefits
A nuclear medicine diagnostic procedure for the cardiovascular system involving first transit imaging without blood pool images.
When to Use
- Use J804 when performing a first-pass radionuclide angiocardiography to assess cardiac function or shunt detection without the acquisition of subsequent blood pool images.
- Use J804 as a supplementary code when performing a blood pool study in conjunction with bone scintigraphy (J850 or J851) to assess localized vascularity.
Common Pitfalls
- Billing J804 alongside any SPECT code is prohibited; the system will reject the claim due to the inherent incompatibility of these imaging modalities.
- Attempting to bill the technical component for an inpatient or a patient admitted within 24 hours of the procedure will result in a rejection, as J804 is restricted to outpatient settings.
- Claiming the 30% data manipulation add-on for simple image processing like smoothing or background subtraction is a frequent audit trigger; it is only payable for advanced quantification providing unique diagnostic data.
Billing Tips
- If performing advanced quantification that provides significant diagnostic information beyond visual inspection, ensure the claim includes the 30% add-on, provided no SPECT imaging was performed.
- When J804 is used for a blood pool study alongside J850 or J851, ensure the clinical documentation clearly justifies the necessity of the vascular assessment to support the dual billing.
