CPT code 58340: Uterine catheterization, for hysterosalpingography or sonohysterography2026 Medicare rate & RVUs

Medicare pays $236.81 for 58340 nationally in the office and $52.11 in a hospital or facility. Local office rates run $205.86–$327.71.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
