Z546 – Barron ligation(s)
OHIP Psychiatric Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Barron ligation(s) is a surgical procedure for the treatment of hemorrhoids. This service is designated with a '#' prefix, indicating that for services performed in a hospital or an Integrated Community Health Services Centre (ICHSC), the facility costs (premises, equipment, supplies, and personnel) are funded through the facility's budget and not billed by the physician. See for details. This service is limited to a maximum of six claims per patient in any one-year period.
When to Use
- Use Z546 for the application of rubber bands to internal hemorrhoids in an office setting.
- Use Z546 when performing a standalone ligation procedure, as it is not eligible for payment when billed with other surgical procedures like S247 (hemorrhoidectomy) on the same site.
Common Pitfalls
- Billing Z546 more than six times in a rolling 12-month period will trigger an automatic rejection.
- Attempting to bill an assistant fee for Z546 will result in a rejection, as the code explicitly lists 'Asst: nil'.
Billing Tips
- Since Z546 is a '#' prefixed code, ensure you do not bill for facility or tray fees if the procedure is performed in a hospital or ICHSC, as these are covered by the facility budget.
