Appendix E - General Site Codes

The General Site Codes are used for coding several data items: sites of metastases, sites of radiation therapy, and sites of recurrence. The first 44 codes are essentially the same as the first 44 site group codes found in Appendix C, which are based on the ICD-O topography and morphology classifications. General Site Codes from 67 to 99 are additional names of parts of the body that may be useful in coding metastatic or radiation sites.
