What 74742 covers

Selective fallopian tube imaging uses catheterization through the cervix to place contrast for radiographic evaluation of the tubes. It can show whether a tube is open or obstructed and is commonly used in infertility assessment. Gynecology and radiology teams may provide the catheterization, imaging, and interpretation in an outpatient or hospital setting.

Medicare assigns CPT 74742 physician fee schedule status C, meaning there is no national payment amount and the Medicare Administrative Contractor prices each claim. The unmodified code represents the global service, including technical imaging work and professional interpretation. When billed separately, modifier 26 identifies the professional interpretation and modifier TC identifies the technical component, including equipment and staff.

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.

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.
