Z615 – Filiform and follower urethral dilation
OHIP Psychiatric Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
Z615 is a surgical procedure code. Suffix 'A' is used by the physician performing the procedure, and suffix 'C' by the anaesthesiologist. Surgical assistance (suffix 'B') is not a payable service for this code. Admission Assessment Rule: As per page , for procedures with a 'Z' prefix, an admission assessment by a surgical specialist who has assessed the patient prior to admission for the same illness is deemed a specific re-assessment. Anaesthesia: The anaesthesia service fee is calculated based on basic units (not specified in the provided context) plus time units as defined on page . Additional extra units for anaesthesia may be applicable based on patient age, ASA status, and other factors as listed on page . Premiums: This service is eligible for several add-on premiums, including: - Age-based premiums for patients under 16 years of age (see ). - After Hours Procedure Premiums (E409, E410) for non-elective services (see ). - Trauma Premium (E420) for qualifying trauma patients (see ).
When to Use
- Use Z615 when performing a formal filiform and follower urethral dilation procedure, which inherently includes the required bladder catheterization.
- Select Z615 for urethral stricture management where the filiform and follower technique is specifically utilized, rather than standard dilation codes.
Common Pitfalls
- Attempting to bill surgical assistance (suffix B) for this procedure will result in rejection, as it is not a payable service for Z615.
- Billing Z615 alongside Z619, Z620, Z621, or Z622 on the same day is a common error that leads to the secondary codes being paid at nil.
- Failing to recognize that the admission assessment is considered a specific re-assessment if you have previously assessed the patient for the same illness within 90 days.
Billing Tips
- Ensure you apply the appropriate age-based premium (10% to 30%) if the patient is under 16 years of age, as this is a surgical procedure code eligible for these increases.
- If performing this procedure non-electively after hours, append the E409 or E410 premium to the Z615A claim to capture the 50% or 75% increase respectively.
