Z628 – Cystoscopy and diagnostic Ureteroscopy - above intramural
OHIP Psychiatric Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
A surgical procedure for diagnostic ureteroscopy performed above the intramural portion of the ureter. This is a surgical procedure payable to the surgeon (suffix A) and includes anaesthesia services (suffix C). The anaesthesia fee is calculated using 6 base units plus time units as described on page . This service can be enhanced with several add-on procedures, including:
- E819: diagnostic ureteroscopy of second ureter
- E822: ureteroscopy to upper third of ureter or renal pelvis
- E760: with removal of calculus
- E761: intracorporeal lithotripsy by any method
- E820: with biopsy of one or more sites
- E823: resection and fulgarization of tumours
Note: Z628 is not eligible for payment with Z638.
When to Use
- Use Z628 when performing a diagnostic ureteroscopy that extends beyond the intramural portion of the ureter into the mid or upper ureter.
- Use Z628 as the primary base code when performing ureteroscopy to facilitate add-on procedures like E760 for calculus removal or E820 for biopsy.
Common Pitfalls
- Billing Z628 in combination with Z638 will result in a rejection, as these are mutually exclusive codes.
- Attempting to bill Z628 for procedures that do not reach beyond the intramural ureter; ensure the scope placement meets the 'above intramural' criteria.
Billing Tips
- Always append the appropriate add-on codes (e.g., E822, E760, E761) to Z628 to capture the full scope of the surgical intervention performed during the same session.
- Ensure anaesthesia services are billed using the 6 base units plus time units as specified in GP93, as these are included in the surgical fee structure for Z628.
