<< Historical Staging and Coding Manuals

Appendix C brings together the site-specific instructions needed to abstract a case, facilitating efficiency and accuracy. The site-specific coding modules include SEER Coding Guidelines, Extent of Disease, and Surgery of Primary Site codes.1

New for 2021 are the Site-Specific Neoadjuvant Therapy Effect coding documents. Links to the applicable coding document(s) have been added to each site in Appendix C.

General instructions in the main manual are applicable in the absence of site-specific instructions. All modules include the extent of disease and surgery codes, and solid tumor coding rules. Some modules include site-specific coding guidelines. Additional site-specific coding instructions are found in SEER*RSA, the SSDI manualExternal Web Site Policy (PDF), and the Grade manualExternal Web Site Policy (PDF).
