California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures for Hospitals
Numeric codes summarize each modality of treatment (surgery, radiation, chemotherapy, etc.). For each modality except surgery, code a summary of the entire first course of treatment. See Section VI.2 for coding each surgery field.
In the field provided, assign a separate code to that portion of the treatment administered at the reporting facility.
Beginning with cases diagnosed January 1, 1998, treatment given by a physician on the medical staff of a facility should not be recorded as treatment given at that reporting facility.
For cases diagnosed prior to January 1, 1998, treatment given in a staff physician’s office should be recorded as if given at the reporting facility.
The codes for surgical procedures have one or two digits.
The codes for the reason no surgery, reason no radiation, reason no chemotherapy and reason no hormone therapy have been incorporated into each respective treatment modality field.
Other codes have two digits, with a 00 always meaning no procedure performed for that type of treatment.
Chemoembolization: a procedure in which the blood supply to the tumor is blocked surgically or mechanically and anticancer drugs are administered directly into the tumor. This permits a higher concentration of drug to be in contact with the tumor for a longer period of time. Code as Chemotherapy.
Radioembolization: embolization combined with injecting small radioactive beads or coils into an organ or tumor. Code as Radiation therapy.
Tumor embolization with alcohol or tumor embolization NOS: the intentional blockage of an artery or vein to stop the flow of blood through the desired vessel. Code as Other therapy, see Section VI.8.1
