Z906 – Removal of drainage tube(s) under general anaesthetic, unilateral
OHIP Psychiatric Code — AURAL SURGICAL PROCEDURES · Schedule of Benefits
Unilateral removal of drainage tube(s) from the ear, performed under general anaesthetic. The '#' prefix indicates that when this service is provided in a hospital or Integrated Community Health Services Centre (ICHSC), the cost of premises, equipment, supplies, and personnel is funded separately and not included in the physician fee, as per . A note specifies that a contralateral procedure is payable at 85% of the listed fee.
When to Use
- Use Z906 when performing the surgical removal of a ventilation tube (grommet) from the tympanic membrane under general anaesthetic.
- Use Z906 for unilateral removal; if performing the procedure bilaterally, bill Z906 for the first ear and Z906 at 85% for the second ear.
Common Pitfalls
- Do not bill Z906 if the tube removal is performed in the office setting without general anaesthetic, as this code specifically requires GA.
- Avoid billing Z906 in conjunction with other major ear surgeries unless the removal is a distinct, separate procedure from the primary surgical site.
Billing Tips
- Ensure the contralateral procedure is submitted as a second line item with the appropriate 85% fee adjustment to avoid manual review or rejection.
- Apply the relevant age-based surgical premium (e.g., AGE_PREMIUM_LT16Y) to the base fee of Z906 to maximize the claim value for pediatric patients.
