What 77417 covers

Radiation oncology practices report 77417 for imaging of radiation treatment ports—views used to check treatment-field position against the planned treatment. These images help verify field placement during a course of radiation therapy. The code identifies port-image work rather than delivery of the therapeutic radiation dose or management of the treatment course. Radiation oncology teams use port images to assess setup and targeting.

For Medicare physician fee schedule purposes, 77417 has status B (bundled): Medicare never pays it separately, and payment is included in payment for other services. The neighboring codes 77402, 77407, and 77412 identify radiation treatment delivery at different levels; 77417 identifies port imaging rather than treatment delivery. Port imaging is distinct from radiation treatment management.

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.

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.
