California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
Some combinations of morphology and site codes are rejected because another site code more accurately reflects the tissue of origin.
Site C40.0-C41.9 (bone) with histology 8070 (squamous cell carcinoma) is possible.
Contact the regional or central registry for coding assistance, if required.
Example: a liposarcoma (8850/3) arising in the abdominal wall should be coded as site C49.4, soft tissues of abdomen, instead of C76.2, abdomen, NOS.
The following are combinations of morphology and site codes that are rejected:
