C220 8000-8157, 8162-8169, 8190-9136, 9141-9582, 9700-9701 Summary Stage only
C220 8170-8175 TNM 7 and Summary Stage
C221 8170-8175 Summary Stage only

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

C220 Liver C221 Intrahepatic bile duct **Note 1:** This schema is based on the UICC chapter *Liver-Hepatocellular Carcinoma* pages 110-113. * Primary site C221 with histologies 8170-8175 is not listed in this chapter of the UICC manual; however, it is included in this schema, but is not TNM staged **Note 2:** For primary site C220 and cholangiocarcinoma histologies (M-8160, 8161, and 8180), see the Bile DuctsIntraHepat schema. **Note 3:** Although the presence of cirrhosis is an important prognostic factor, it does not affect the TNM classification, being an independent prognostic variable. **Note 4:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Liver and Intrahepatic Bile Ducts* chapter on page 108 of the [SS2000 on-line manual](http://seer.cancer.gov/tools/ssm/SSSM2000-122012.pdf#page=108).
