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.

58350 billing questions

Does 58350 reopen a blocked fallopian tube?

No. It reports dye-based assessment of tubal patency. Transcervical catheter introduction intended to diagnose or reestablish patency is described by 58345.

What documentation supports reporting 58350?

The operative note should identify dye instillation and the observed passage through the tubes, including whether patency was demonstrated. A statement that tubal patency was checked without documenting chromotubation is not enough to establish this service.

How does CMS handle 58350 with another procedure in the same session?

Under the standard multiple-procedure reduction, CMS pays the highest-valued procedure in full and the others at 50%. The operative record should identify the distinct procedures performed.

How is bilateral chromotubation reported?

CMS identifies 58350 as bilateral and pays modifier 50 at 150%. The record should support assessment of both tubes.

Can an assistant surgeon or co-surgeon be reported for 58350?

CMS does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

Are postoperative visits included?

Related postoperative visits during the 10-day global period are included in the procedure 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.
