California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
This data field captures the age of the patient at the time of diagnosis.
Age at First Diagnosis is a required field. Usually, the Age at First Diagnosis is calculated and generated by the abstracting software.
If the Age at First Diagnosis is not calculated and generated by the abstracting software, calculate the age and enter it into this field.
Document the patient’s age in either the physical exam or remarks text field.
Include text verification in the remarks text field when the patient is 100 years or older.
