Ultrasound imaging
About 76831: Saline infusion uterine cavity ultrasound
Reports ultrasound evaluation of the uterine cavity during saline infusion, commonly used to investigate abnormal bleeding or suspected intracavitary lesions.
During saline infusion sonohysterography, a clinician passes a catheter through the cervix and introduces sterile saline while ultrasound images show the distended uterine cavity. The added fluid helps reveal findings such as an endometrial polyp or submucosal fibroid. Gynecologists commonly perform the procedure in an office or imaging setting; radiology teams may provide the imaging and interpretation. It is used in evaluations of abnormal uterine bleeding and selected infertility workups.
Report 76831 for the ultrasound imaging and interpretation of the cavity during saline infusion. Documentation should support the clinical indication, the infusion and imaging performed, and the findings. Catheterization and saline introduction are represented by 58340 when separately reportable; that code describes the procedural step rather than the ultrasound interpretation. Billing 76831 without a component modifier represents the global service. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service. When multiple diagnostic imaging procedures are reported, the applicable multiple procedure reduction applies to both the professional and technical components.
