California Cancer Registry Volume I: Abstracting and Coding Procedures for Hospitals
Use the following codes for recording radiation therapy in the summary field.
Radiation - Regional RX Modality and Radiation - Boost RX Modality, are required to code first course radiation therapy.
Radiation to the brain and CNS for lung and leukemia cases is to be coded in the Radiation – Regional RX Modality and Radiation – Boost RX Modality fields.
The field "Radiation Therapy at this Hospital" is no longer required by the CCR.
These instructions apply to cases diagnosed January 1, 2003 and forward.
For additional information regarding Radioactive Implants, see V.3.1.2.
Note: CCR does not include codes 7 and 8 in our instructions. We collect this information in the Reason for No Radiation Field. The CoC discontinued collection of this item in 2003 when FORDS was implemented. For CoC, codes 7 and 8 were used for tumors diagnosed before 1996, but should have been converted to 0 in this field and to the appropriate code in the new field Reason for No Radiation [1430]. SEER continues to use codes 7 and 8 for all years. See Chapter V, Unresolved Issues, for further discussion.
