What 75801 covers

This code represents radiologic supervision and interpretation of contrast imaging of the lymphatic vessels in one extremity—an arm or a leg. Contrast is introduced into the lymphatic system so the channels can be imaged. The study may be used to evaluate lymphatic drainage or suspected obstruction. A radiologist typically interprets the images in a hospital or other imaging setting.

Medicare assigns this service physician fee schedule status C, or carrier priced: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The code has professional and technical components. Report modifier 26 for the interpretation or modifier TC for the equipment and staff when those components are billed separately; without a modifier, the code represents the global service.

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.

75801 billing questions

When should I report 75801 rather than 75803?

75801 is for imaging one extremity. Use 75803 when the study covers both extremities.

How does 75801 differ from 75805 or 75807?

75801 describes lymphatic imaging of an extremity. Codes 75805 and 75807 describe imaging of other lymphatic regions, the pelvis and thorax, respectively.

When should modifier 26 or TC be used?

Use modifier 26 for the professional interpretation and modifier TC for the technical portion when billing those components separately. Without either modifier, the code represents the global service.

Does 75801 describe a venogram?

No. It describes imaging of lymphatic vessels. Venography codes, such as 75820, concern veins in an extremity.

How is 75801 priced by Medicare?

It has physician fee schedule status C. CMS publishes no national payment; the Medicare Administrative Contractor sets payment for each claim.

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.
