E777 – Cystometrogram
OHIP Surgical Assists Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
This service is an add-on to a diagnostic cystoscopy. It involves performing a cystometrogram to assess bladder function, specifically how the bladder muscle works and its capacity. The procedure may also include a urethral pressure profile if required. This code must be claimed in conjunction with a primary cystoscopy procedure, such as `Z606 (Diagnostic cystoscopy) or Z607` (Repeat cystoscopy).
When to Use
- Use E777 when performing a formal cystometrogram to evaluate bladder capacity and detrusor function during the same operative session as a diagnostic cystoscopy (Z606).
- Apply this code when a urethral pressure profile is conducted as part of the bladder assessment alongside a repeat cystoscopy (Z607).
Common Pitfalls
- Billing E777 as a standalone service will result in an automatic rejection because it is strictly an add-on code requiring a primary Z606 or Z607 claim.
- Attempting to bill E777 for a simple diagnostic cystoscopy that does not include the specific physiological measurements of a cystometrogram is an audit risk for upcoding.
Billing Tips
- Ensure both the primary cystoscopy (Z606/Z607) and the E777 add-on are submitted on the same claim to maintain the required linkage for payment.
