About 77318: Complex brachytherapy dose planning
Reports complex dose-distribution planning for brachytherapy, using the implant or applicator geometry to shape the prescribed radiation dose.
A radiation oncologist directs this planning service, with a medical physicist or dosimetrist typically developing the dose distribution. The work maps the brachytherapy source arrangement—such as sources placed through an interstitial implant or an intracavitary applicator—and evaluates how dose covers the target while limiting exposure to nearby tissues. It may support temporary or permanent implant treatment in settings such as a radiation oncology department or hospital.
Choose the complex level when the documented source arrangement and planning work meet the CPT criteria for complex brachytherapy planning; the treatment site alone does not determine the level. Keep the plan and supporting dose-distribution documentation in the record, including relevant source or applicator geometry and the prescription being planned. CMS recognizes professional and technical components: report modifier 26 for the interpretation, TC for equipment and staff, or neither modifier when billing the global service.
CMS billing rules for 77318
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

77318 billing questions
How is 77318 distinguished from 77316 and 77317?
All three are brachytherapy planning levels. Select 77318 only when the source arrangement and planning meet the complex-level CPT criteria; do not select it solely because of the treatment site.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service involving equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports the complex level?
Retain the brachytherapy plan and documentation of the source or applicator arrangement, planned dose distribution, and prescription. The record should support why the plan meets the complex level.
Is 77318 for an external-beam isodose plan?
No. It is for brachytherapy source planning. External-beam isodose planning is represented by a different code family, including 77306 and 77307.
Does the treatment site determine the code level?
No. The level depends on the complexity of the brachytherapy planning work and source arrangement, not simply whether treatment is for the prostate, cervix, or another site.
