Operation Definition
Single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means
Procedure Overview
Fluoroscopy of the female reproductive system captures a continuous, real-time X-ray image, most commonly during a hysterosalpingogram, in which contrast dye is injected through the cervix so the physician can watch it fill the uterine cavity and pass through the fallopian tubes. This live view is used mainly to evaluate infertility, confirm tubal patency, or check the position of an intrauterine device, since it shows dynamic filling and flow rather than a single frozen moment.
Because the image is generated continuously as contrast moves through the anatomy, fluoroscopy can reveal blockages, structural abnormalities like a septate uterus, or scarring that a static image would miss. The exam is typically brief but does involve ongoing radiation exposure for the duration of the study, and it is not performed during pregnancy.
Anatomy & Axis Detail
Fallopian Tube, Left
Fluoroscopic evaluation of the left fallopian tube follows the same hysterosalpingographic technique used on the right, with contrast tracked from the uterine cornu through the tubal lumen to assess whether it spills into the peritoneal cavity, indicating patency, or is arrested, suggesting obstruction. The left tube's proximity to the sigmoid colon can occasionally complicate interpretation if bowel motion or overlapping loops interfere with the fluoroscopic field, so the radiologist adjusts positioning to isolate the adnexal region during image acquisition. This real-time contrast study is central to infertility evaluation and can also reveal tubal shape abnormalities, such as a beaded or occluded segment from prior infection, that would not be apparent on a non-contrast film of the same structure.
Contrast: Other Contrast
Other Contrast captures imaging studies using a contrast medium that is neither high- nor low-osmolar iodinated agent, such as barium sulfate for gastrointestinal studies or gadolinium-based agents for certain applications outside standard MRI classification within this axis. It is used when the contrast administered does not fit the osmolarity-based iodinated categories, distinguishing it from those specific classes and from studies performed with no contrast.
Coding & Documentation
Correct code assignment requires the report to confirm real-time imaging was performed with contrast material actively tracked through the reproductive structures, distinguishing it from a plain film taken before or after the contrast study. Coders often mistakenly assign a plain radiography code to the pre-contrast "scout" image obtained at the start of the same encounter, when only the fluoroscopic portion with contrast should be coded under this family. Documentation should also specify which structures the contrast reached (uterus alone versus uterus and tubes) since findings of tubal occlusion are part of the clinical picture, not the coding decision itself.
Commonly Confused With
Plain radiography of the female reproductive system is the main point of confusion, since both may occur in the same visit; the distinguishing factor is whether imaging was continuous and contrast-guided (fluoroscopy) or a single static exposure. This family is also distinct from ultrasonography or MRI of the same body system, which do not involve injected radiographic contrast or ionizing radiation and are used more often for mass or anatomic characterization than for functional tubal assessment.
