Bladder catheterization done by the physician in the patient's home, for acute retention, catheter or tube change, or medication.

What it covers

Z603 is catheterization performed in the patient's home (T8). Catheterization in hospital or office is Z611 (T8).

It is only payable for acute retention, change of a Foley catheter or suprapubic tube, or instillation of medication (T8).

Billing rules

• Payable only for acute retention, change of Foley catheter or suprapubic tube, or instillation of medication (T8).
• Must be done personally by the physician (T8).
• Not payable with E751 (chemotherapy instillation at cystoscopy) (T7) or with Z610 (intravesical BCG or chemotherapy) (T8).
• A Z-code is an independent operative procedure: if your major pre-operative visit was in the past 12 months, only a minor assessment (family physicians) or partial assessment (specialists) is payable before it that day; if the major pre-op visit is the same day, no other assessment before it is payable (SP4 §13).

Common rejections

• ADH: OHIP describes this as 'Cannot be billed together': Z603 was billed with Z610 or E751, which it is not payable with (T7, T8).
