Z545
Z545 – Thrombosed haemorrhoid(s)
OHIP Psychiatric Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use Z545 for the acute surgical incision and drainage of a thrombosed external haemorrhoid when performed in a clinic or hospital setting.
- Use this code when the clinical documentation confirms the presence of a thrombus requiring incision, distinguishing it from simple haemorrhoid banding or injection.
Common Pitfalls
- Billing Z543 (anoscopy) in addition to Z545 will result in a rejection, as the fee for Z545 explicitly includes the anoscopy procedure.
- Failing to append E542 when the procedure is performed in a physician's office or non-hospital facility results in the loss of the eligible office-setting premium.
Billing Tips
- Ensure the procedure is clearly identified as an incision of a thrombosed haemorrhoid to avoid confusion with ligation or injection codes (e.g., Z541 or Z544) which have different clinical indications.
