What 77317 covers
This code represents intermediate-level isodose planning for brachytherapy: calculating and reviewing how radiation from implanted or applicator-positioned sources is distributed through the target and nearby tissues. It is used in radiation oncology, including treatments such as intracavitary gynecologic brachytherapy or interstitial implants. A radiation oncologist directs the prescription, while a medical physicist or dosimetrist may perform the planning calculations.
Select this level when the documented work meets the intermediate category in the brachytherapy planning scale, rather than the simple or complex level. The record should support the source or applicator arrangement, prescribed dose, dose-distribution calculations, and plan review. CMS recognizes professional and technical components: modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and billing without either modifier 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.

77317 billing questions
How do I distinguish 77317 from 77316 or 77318?
All three are brachytherapy isodose planning levels. Use 77317 when the documented plan meets the intermediate category, not the simple or complex category.
Is 77317 for treatment planning or radiation delivery?
It reports the brachytherapy dose-distribution plan, not the placement of sources or delivery of radiation.
When should modifier 26 or TC be reported?
Modifier 26 identifies the professional interpretation, and TC identifies the technical service involving equipment and staff. Without either modifier, the code represents the global service.
What documentation supports the intermediate planning level?
Document the source or applicator arrangement, prescribed dose, dose-distribution calculations, and review of the resulting plan, with support for the intermediate level.
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.
