Z566 – Barron ligation(s) plus cryotherapy
OHIP Psychiatric Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service involves the performance of Barron ligation(s) in combination with cryotherapy. As a service prefixed with '#', when rendered in a hospital or Integrated Community Health Services Centre (ICHSC), the facility costs (premises, equipment, supplies, personnel) are funded through the institution's budget and not billable to the patient, as detailed in . The service is not eligible for payment for a surgical assistant (Asst: nil).
When to Use
- Use Z566 when performing a combined procedure of Barron ligation and cryotherapy during the same operative session.
- Use this code for the treatment of symptomatic internal hemorrhoids where both mechanical ligation and cryo-ablation are clinically indicated.
Common Pitfalls
- Billing Z566 in addition to Z565 (Barron ligation) or Z546 (Cryotherapy) for the same session is considered unbundling; Z566 is the comprehensive code for the combined service.
- Exceeding the annual limit of 6 services per patient will trigger automatic claim rejections.
- Attempting to bill for a surgical assistant is a common error, as this code is explicitly designated with 'Asst: nil'.
Billing Tips
- Ensure your operative report clearly documents both the ligation and the cryotherapy components to justify the use of the combined code Z566 over single-modality codes.
- Verify the patient's annual history for Z566 to ensure you remain within the maximum of 6 services per rolling year.
