Diagnostic ultrasound
About 78730: Bladder ultrasound with residual assessment
Reports image-documented ultrasound assessment of the urinary bladder, including postvoid residual, when added to a qualifying primary imaging procedure.
This service captures real-time ultrasound images of the urinary bladder, including assessment of residual volume after a patient voids. It is used when clinicians evaluate incomplete emptying or suspected urinary retention, including in patients with lower urinary tract symptoms or neurogenic bladder. A sonographer generally acquires images in an office or imaging setting, and the interpreting physician reviews the images and documents the findings.
Report 78730 only with a qualifying primary procedure; it is an add-on, not a stand-alone bladder scan. The record should support the clinical indication, image acquisition, interpretation, and any postvoid measurement. CMS treats payment as within the primary procedure’s global period. The diagnostic service has professional and technical components: use modifier 26 for interpretation only, TC for equipment and staff only, or neither modifier when billing the global service.
