Appendix C: Site Specific Coding Modules
2012 SEER Coding and Staging Manual

<< 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; Equivalent Terms, Definitions, Tables, Charts and Illustrations; Multiple Primary Rules; Histology Coding Rules; Collaborative Stage Coding Instructions1 and Surgery of Primary Site codes2.

General instructions in the main manual are applicable in the absence of site-specific instructions. All modules include the collaborative stage and surgery codes, and multiple primary and histology coding rules. Some modules include site-specific coding guidelines. The goal is to have stand-alone modules for major anatomic sites.

Summary of Changes for Appendix C (PDF) provides the list of changes included in this release.

The surgery codes in this document are identical to the FORDS manual; only formatting and annotations may vary.
