California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
Reportable cases are cases that the registry is required to collect and report.
Every reporting facility must report all cases, inpatient or outpatient, admitted on or after the regional registry's reference date with a neoplasm classified in the morphology section of ICD-O-3 (International Classification of Diseases for Oncology, Third Edition, 2000) as malignant or in situ, including those discovered at an autopsy.
The only exceptions are certain carcinomas of the skin. See Skin Reportability.
Neoplasms described by terms synonymous with in situ are reportable. See Terms Indicating In Situ for a list of these terms.
Benign and uncertain behavior intracranial and central nervous system (CNS) tumors became reportable along with newly reportable histologies published in ICD-O-3. This applies to cases diagnosed January 1, 2001 and forward.
Other benign neoplasms are not reportable.
For a list of reportable and non-reportable neoplasms, refer to the morphology section of ICD-O-3.
