About 77770: Single-channel HDR brachytherapy
Reports one fraction of remote afterloading high-dose-rate brachytherapy for interstitial or intracavitary treatment using a single channel.
A radiation oncologist uses a remote afterloader to send a radioactive source through an applicator or catheter into an interstitial or intracavitary treatment site. This code represents the single-channel service for one fraction; examples of treatment sites include gynecologic cavities and implanted interstitial catheters. The provider manages delivery of the planned HDR treatment fraction. Services are commonly furnished in a hospital radiation oncology department or an outpatient radiation treatment center.
Select this code when the fraction uses one channel, rather than the channel counts represented by 77771 or 77772. The record should support the treatment site, fraction delivered, remote afterloading method, and number of channels used. Report the global service without a component modifier, or report modifier 26 for the professional component and TC for the technical component when billing them separately. CMS lists both components as separately priced.

77770 billing questions
How does 77770 differ from 77771 and 77772?
77770 represents a single channel per fraction. The sibling codes represent higher channel-count levels: 77771 for 2–12 channels and 77772 for more than 12.
Is 77770 reported per treatment course or per fraction?
It is reported for each qualifying treatment fraction, not once for the entire course. Documentation should identify the fraction delivered and channel count.
Which modifiers identify the professional and technical components?
Modifier 26 identifies the professional component, and modifier TC identifies the technical component. Without either modifier, the claim represents the global service.
What documentation supports choosing the single-channel level?
The treatment record should show remote afterloading HDR delivery and that one channel was used for the fraction. The treatment site and fraction should also be identifiable.
Is 77770 the code for surface HDR brachytherapy?
No. 77770 is for interstitial or intracavitary HDR treatment. Codes 77767 and 77768 describe HDR treatment of a skin surface.
Where these rates come from
