What 58340 covers

A clinician, commonly a gynecologist or fertility specialist, passes a narrow catheter through the cervix into the uterine cavity and introduces contrast or saline for imaging. In hysterosalpingography, contrast helps show the uterine cavity and fallopian tubes on imaging; in saline-infusion sonohysterography, saline outlines the cavity during ultrasound. These procedures are commonly performed in an office or imaging setting during evaluation of infertility, tubal patency, or suspected intracavitary abnormalities.

Report 58340 for the catheter placement and fluid introduction, supported by documentation of the method and indication; report the applicable imaging service separately when performed. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

58340 billing questions

How is 58340 different from 74740?

58340 covers the transcervical catheter placement and fluid introduction. Code 74740 represents the radiological supervision and interpretation for hysterosalpingography.

Can 58340 be reported with 76831?

Yes, when saline-infusion sonohysterography is performed, 58340 represents the catheter placement and saline introduction, while 76831 represents the ultrasound service.

What documentation supports 58340?

Document the indication, catheter placement through the cervix, and introduction of contrast or saline for the imaging procedure.

Does modifier 50 apply when both fallopian tubes are evaluated?

How does the 0-day global period affect same-day care?

Same-day preoperative and postoperative care is included in the procedure's payment.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
