What 74740 covers

Hysterosalpingography uses contrast introduced through the cervix and fluoroscopic imaging to assess the uterine cavity and whether contrast passes through the fallopian tubes. It is commonly performed during infertility evaluation or when tubal obstruction or an abnormal uterine cavity is suspected. A radiologist typically provides the imaging supervision and interpretation; a gynecologist or other qualified clinician may place the catheter and introduce the contrast under a separate service when supported by the work performed.

Report 74740 for the radiologic examination and interpretation of both the uterus and fallopian tubes, not for catheter placement alone. The record should support the indication, contrast study, images obtained, and findings such as cavity contour, tubal filling, and contrast spill. CMS recognizes professional and technical components: bill modifier 26 for interpretation, modifier TC for equipment and staff, or neither modifier for the global service. The professional and technical components have separately priced modifiers.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

74740 billing questions

When should 74740 be selected instead of 74742?

Use 74740 when the contrast study evaluates the uterine cavity and fallopian tubes. 74742 is the more focused radiologic examination of the fallopian tube.

Can catheter placement be reported separately?

billing code 58340 describes catheterization and introduction of saline or contrast for hysterosalpingography or saline infusion sonohysterography. Report it only when that work is performed and documented; 74740 represents the radiologic study and interpretation.

Which modifier identifies the radiologist's interpretation?

Append modifier 26 for the professional component. Modifier TC identifies the technical component, while reporting 74740 without either modifier represents the global service.

What should the report document?

Document the clinical indication, contrast imaging performed, and interpretation of the uterine cavity and fallopian tubes, including relevant findings such as tubal filling or contrast spill.

Is 74740 the same as saline infusion sonohysterography?

No. 74740 is a contrast radiographic examination of the uterus and fallopian tubes. Saline infusion sonohysterography uses ultrasound to evaluate the uterine cavity.
