Appendix B: Resources for Cancer Registrars

SEER has several resources related to ICD-10-CM for cancer registrars. These include:

• Annual Casefinding List – The FY (fiscal year) ICD-10-CM casefinding list goes into effect on October 1 of every year and ends on September 30.
• The current casefinding list includes all the cancer codes. There are two sections:  https://seer.cancer.gov/tools/casefinding/.
• Reportable – This section lists the cancers that are reportable. This includes all the malignant tumors (C codes), in situ tumors and benign brain tumors (D codes).
• Supplemental – This section includes the remaining benign tumors, uncertain and unspecified tumors (D codes), neoplasm related conditions, complications of cancer treatment, abnormal findings and encounters for cancer care (Z codes).

Note: Do not use the casefinding list for reportability.

• Conversion Files – The conversion files map the following: http://seer.cancer.gov/tools/conversion/.
  
  Note: ICD-10 (no CM) is used for cause of death coding, normally done in central registries.
