J870 – Thyroid uptake - repeat
OHIP Cardio-Thoracic Surgery Code — NUCLEAR MEDICINE - IN VIVO · Schedule of Benefits
This service represents a repeat measurement for a thyroid uptake study. According to the definition of 'repeat' in the of the Schedule of Benefits, this implies it is the same service as J817 rendered to the same patient by the same physician on the same day. The procedure involves administering a radioactive tracer and using a gamma probe to measure its accumulation in the thyroid gland at various time points to assess thyroid function. The service has both a professional component (P Fee) and a technical component (H Fee).
When to Use
- Use J870 specifically for a secondary thyroid uptake measurement performed on the same day as the initial J817 study.
- Apply this code when the clinical protocol requires multiple time-point measurements (e.g., 4-hour and 24-hour uptake) within the same calendar day.
Common Pitfalls
- Billing J870 as a standalone service without a corresponding J817 on the same day will result in an automatic rejection.
- Failing to maintain documented evidence of quality assurance processes for the radioactive tracer administration is a common audit failure point.
- Attempting to bill J870 for a follow-up visit on a different calendar day is incorrect; subsequent days require a new primary J817 claim.
Billing Tips
- Ensure the technical (H) and professional (P) components are correctly identified and billed to reflect the full scope of the repeat procedure.
- If the repeat measurement occurs during an after-hours special visit, ensure you select the appropriate C-series premium that aligns with the timing and patient setting.
