California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures for Hospitals
For cases diagnosed January 1, 2010 and forward, or following installation of CSv2 software, refer to Collaborative Stage Data Collection System Coding Instructions.
For intracranial and CNS benign and borderline tumor cases diagnosed January 1, 2004 and prior to January 1, 2010, apply Collaborative Staging and Coding Manual.
For intracranial and CNS benign and borderline tumor cases diagnosed from January 1, 2001 to December 31, 2003, the CCR does not require that these cases be staged. The CCR recommends that these cases be coded as EOD 99 (Unknown). If your registry uses SEER Summary Stage, it is recommended that these cases be coded to 9.
