Z595 – Replacement of drainage catheter in abdominal abscess
OHIP Psychiatric Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service is for the replacement of a drainage catheter in an abdominal abscess. It is typically a follow-up procedure to an initial drainage, such as Z594.
When to Use
- Use Z595 for the routine exchange or replacement of an existing abdominal abscess drainage catheter that has become dislodged or requires upsizing.
- Use Z595 when the initial drainage procedure (Z594) has been completed and the patient requires a subsequent catheter maintenance visit.
Common Pitfalls
- Do not bill Z595 in conjunction with Z594 on the same day, as Z595 is intended for follow-up maintenance rather than the initial placement.
- Avoid billing Z595 if the catheter replacement is performed as part of a more comprehensive surgical procedure that includes a global fee covering the drainage management.
Billing Tips
- Ensure the medical record clearly distinguishes the replacement procedure from the initial insertion to avoid claims being flagged for duplicate billing.
- If the procedure is performed after hours or on weekends, ensure you append the appropriate E409 or E410 premium to the Z595 fee to maximize reimbursement.
