• Not payable in a hospital or ICHSC (S19).
• Rigid sigmoidoscopy (Z535, Z536, Z592) outside hospital uses E746 instead (S25).

Common rejections

• ADF: OHIP describes this as 'Corresponding Procedure Invalid, Omitted or Paid at zero': the base procedure (Z491–Z499, Z512, Z555 or Z580) is missing from the claim, invalid, or paid at zero. Add-ons are payable only with their base code.
