California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures for Hospitals
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 Section II.1.4.
In addition, report cases when:
Neoplasms described by terms synonymous with in situ are reportable. See Section V.5.8.1 for a list of these terms.
Effective with cases diagnosed January 1, 2001, benign and uncertain behavior intracranial and central nervous system (CNS) tumors became reportable along with newly reportable histologies published in ICD-O-3.
Although borderline ovarian tumors changed behavior in ICD-O-3 from /3 (malignant) to /1 (borderline), the CCR will continue to require reporting them.
Other benign neoplasms are not reportable.
For a list of reportable and non-reportable neoplasms, refer to the morphology section of ICD-O-3.
