What 78630 covers

This nuclear medicine study follows a radiotracer through cerebrospinal fluid spaces after intrathecal administration, with images obtained to evaluate CSF circulation and distribution. It is typically performed in a hospital nuclear medicine department or imaging center, with a nuclear medicine physician or radiologist interpreting the study. A clinician may request it when the diagnostic question concerns how CSF moves through the intracranial spaces rather than brain tissue appearance or shunt function alone.

Report 78630 for the CSF scan itself; the medical record should support the clinical question, the study performed, and the interpreting physician’s findings. CMS recognizes professional and technical components: report modifier 26 for the interpretation, TC for the equipment and staff, or neither modifier when billing the global service. The professional and technical services may be billed separately when performed by different entities. The scan’s findings should be distinguished from a targeted CSF leak study, ventricular study, or shunt evaluation when selecting among related nuclear medicine services.
