What 77307 covers

This service develops a dose-distribution plan for external-beam radiation therapy. The radiation oncologist establishes the prescription and treatment approach, with a medical dosimetrist or radiation physicist commonly carrying out planning calculations and preparing the isodose distribution. The plan uses treatment and anatomic information to shape how radiation beams cover the target while limiting exposure to nearby normal tissue. It is performed as part of radiation oncology treatment planning, rather than during delivery of each treatment fraction.

Select the complex planning level based on the documented features of the teletherapy plan, not simply the diagnosis or body site. The record should support the plan’s beam arrangement and complexity, dose calculations, and physician review. Basic dosimetry calculation is included in this planning service. CMS recognizes separately priced professional and technical portions: report modifier 26 for the professional interpretation and modifier TC for equipment and staff; without either modifier, the claim 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.

77307 billing questions

How is 77307 distinguished from 77306?

Both describe teletherapy isodose planning, but 77307 is the complex level and 77306 is the simple level. Use the documented planning features and applicable CPT criteria to select the level.

Can 77300 be reported for the dosimetry calculation?

The basic dosimetry calculation is included in 77307. Do not separately report 77300 for that same calculation.

When should modifier 26 or TC be used?

Use modifier 26 for the professional interpretation and modifier TC for the technical portion involving equipment and staff. A claim without either modifier represents the global service.

Is 77307 used for IMRT planning?

Use 77301 for an IMRT treatment plan. Code 77307 describes complex teletherapy isodose planning rather than the IMRT planning service.

What documentation supports the complex planning level?

Document the treatment prescription, planning method and beam arrangement, dose calculations and distribution, and physician review. The record should show why the plan meets the complex 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.
