What 58350 covers

A gynecologic surgeon performs chromotubation by introducing dye through the cervix and observing whether it passes through the fallopian tubes into the pelvis. It is commonly used during laparoscopy to assess tubal patency in an infertility workup or when tubal disease is being evaluated. The documented service is a dye-based patency assessment; it is not the transcervical catheter procedure used to attempt to reopen an obstructed tube.

Report 58350 when the operative record supports actual chromotubation, including the dye instillation and the observed tubal passage or lack of passage. When other procedures are performed in the same session, CMS applies the standard multiple-procedure reduction: the highest-valued procedure is paid in full and others at 50%. For bilateral reporting with modifier 50, payment is at 150%. The code has a 10-day global period, which includes related postoperative visits during that period. CMS does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

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.
