If you are working with a site/histology that only summary stages and you need to directly code it, please use the SEER Summary Stage 2000 manual

Notes

C240 Extrahepatic Bile Duct

Note 1: This schema is based on the UICC chapter Gallbladder, pages 118-121.

  • In the TNM 7th edition, Cystic Duct was removed from the Extrahepatic Bile Duct staging chapter and added to the Gallbladder staging chapter
  • Site-Specific Factor 25, Schema Discriminator: BileDuctsDistal/BileDuctsPerihilar/CysticDuct is used to discriminate between bile duct distal, bile duct perihilar and cystic duct which are coded to ICD-O-3 code C240

Note 2: In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the Extrahepatic Bile Duct chapter on page 112 of the SS2000 on-line manual.
