Brain Primary Tumor Location
Notes
**Note 1:** This SSDI is effective for diagnosis years 2024+
* For cases diagnosed 2018-2023, leave this SSDI blank
**Note 2:** A data item is needed to distinguish between the Pons and all other subsites within the Brain Stem (C717). Code the site in which the tumor arose.
* Review of radiology reports and physician’s notes are needed to determine the appropriate code. Needle biopsies and surgery are usually too dangerous for these types of tumors, so the best information will be available from radiology reports
