What it covers

E777 is a cystometrogram, including a urethral pressure profile if necessary, done with cystoscopy (T7).

A stand-alone cystometrogram or voiding pressure study is G475, and multichannel urodynamics are G192–G194 (J115).

Billing rules

• E-prefixed cystoscopy add-ons are payable in addition to any S or Z code under the Bladder subheading, or with Z626 or Z628, unless noted otherwise (T6 preamble §4).
• Diagnostic cystoscopy is Z606, or Z607 for a repeat within 30 days (T7).

• Z606 diagnostic cystoscopy (T7).

Common rejections

• ADF: OHIP describes this as 'Corresponding procedure invalid, omitted or paid at zero': E777 was billed without a payable base cystoscopy (such as Z606) for the same patient and day (T6, T7).
