J186 – Transcranial doppler assessment - assessment with power mode doppler
OHIP Cardio-Thoracic Surgery Code — DIAGNOSTIC ULTRASOUND · Schedule of Benefits
Professional component (P) for a transcranial Doppler assessment of the intracranial circulation using power mode Doppler. This service is for the physician's interpretation and report of the study. It falls under the Vascular System category of Diagnostic Ultrasound procedures. Payment Rules: - Only one of J186, J187, or J188 is payable per patient, per physician, on the same day. - Not eligible for payment with J189 for the same patient on the same day.
When to Use
- Use J186 when performing a professional interpretation of a transcranial Doppler study specifically utilizing power mode Doppler for intracranial circulation assessment.
- Select J186 over J187 or J188 when the clinical focus is on the power mode imaging modality rather than standard spectral or color flow Doppler assessments.
Common Pitfalls
- Billing J186 in conjunction with J189 on the same day will trigger an automatic rejection as they are mutually exclusive diagnostic services.
- Submitting J186 alongside J187 or J188 for the same patient on the same day is a common billing error that results in payment denial for the secondary code.
Billing Tips
- Ensure your documentation explicitly references the use of power mode Doppler to justify the selection of J186 over the alternative J187 or J188 codes.
