What 77772 covers
A radiation oncologist uses a remotely afterloaded radioactive source with catheters or an intracavitary applicator to deliver high-dose-rate treatment to a defined target. Common settings include hospital radiation oncology departments and outpatient cancer centers; treatment sites can include the cervix or prostate. This level is distinguished by treatment involving more than 12 channels. Basic dosimetry is included when performed.
Select this code when the documented channel count supports the complex level, rather than the lower channel-count levels. Records should identify the treatment site, applicator or catheter arrangement, channel count, and delivered treatment. CMS lists separately priced professional and technical components: modifier 26 identifies the professional interpretation, while modifier TC identifies equipment and staff; without either 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.

77772 billing questions
How is this code distinguished from 77770 and 77771?
The channel count determines the level: 77772 is for treatment involving more than 12 channels. The lower codes cover fewer channels.
Can basic dosimetry be billed separately?
Basic dosimetry is included when performed as part of this service. The code covers complex HDR interstitial or intracavitary treatment, not a separate dosimetry-only service.
When should modifier 26 or TC be used?
CMS identifies modifier 26 for the professional interpretation and TC for the technical equipment and staff component. Report the code without either modifier for the global service.
What documentation supports the complex level?
Document the treatment site, applicator or catheter configuration, channel count, and treatment delivered. The record should support use of more than 12 channels.
Is this the right code for HDR treatment of a skin surface site?
No. This code is for interstitial or intracavitary treatment; HDR skin-surface treatment is represented by a different code family, including 77767 and 77768.
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.
