For patients with suspected oncological disease of the digestive system, endoscopic examinations are performed as quickly as possible (within 10 working days, outside the general waiting list) under the “Green Corridor” scheme.

Services can only be accessed with a Green Corridor referral. The referral codes for the “Green Corridor” are: Z03.115, Z03.116, and Z03.118–Z03.120.
