STORE Data Item Clarification: I-131 for Thyroid

As referenced in page 10 of the CTR Guide to Coding Radiation Therapy Treatment in the STORE  (Version 1.0), technically, I-131 is effective wherever there are thyroid cancer cells in the body, so there is no specific anatomic treatment volume involved. Therefore, it is recommended coding radioisotope treatments as 98 (Other). While another reasonable option would be to code the volume as 93 (Whole Body), code 93 (Whole Body) has traditionally been reserved for whole body treatment with external beam radiation such as is done prior to bone marrow transplantation. For historical consistency purposes, please use 98 (Other). The next version of STORE will reflect this change.

The CTR Guide to Coding Radiation Therapy Treatment in the STORE may also be found in the Resources section of the National Cancer Database web page.
