What 74450 covers
This service covers the imaging supervision and interpretation for a retrograde urethrocystogram. Contrast is introduced through the urethra, and fluoroscopic images show the urethral passage and bladder. The study may help assess a suspected urethral narrowing, injury, or altered anatomy. A urologist or other qualified clinician may perform the contrast instillation, while a radiologist commonly interprets the images. The examination is performed in a setting equipped for fluoroscopic imaging.
Medicare assigns this CPT code physician fee schedule status C, or carrier priced: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The radiology service has professional and technical components. Report modifier 26 for the interpretation, modifier TC for equipment and staff, or neither modifier for the global service. The related contrast-injection service may be reported separately when performed.
