About 77301: Intensity-modulated radiotherapy treatment plan
Reports computerized IMRT planning that optimizes radiation dose across a target while evaluating dose exposure to nearby critical structures.
This service covers development of a computerized intensity-modulated radiation therapy plan. The team shapes and optimizes radiation fields to deliver the prescribed dose to the target while assessing exposure to organs at risk, often using dose-volume analysis. A radiation oncologist directs and approves the plan, with work commonly performed by medical physicists and dosimetrists in a radiation oncology department or freestanding center. It is planning work, not delivery of the radiation treatment.
Report the code when the record supports an IMRT-specific optimized plan, including the target and critical-structure evaluation, rather than a conventional teletherapy isodose plan. Documentation should identify the treatment plan, prescription, dose evaluation, and physician approval. CMS recognizes professional and technical components: modifier 26 identifies the professional interpretation, modifier TC the equipment and staff, and no modifier represents the global service.
CMS billing rules for 77301

77301 billing questions
When should 77301 be selected instead of 77306 or 77307?
Use 77301 for an IMRT-specific optimized plan with dose-volume evaluation. Codes 77306 and 77307 describe simple or complex conventional teletherapy isodose planning, not IMRT planning.
Does 77301 report radiation treatment delivery?
No. It reports development of the IMRT plan; radiation delivery is a separate service.
How are the professional and technical portions billed?
Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical portion involving equipment and staff. Billing without either modifier represents the global service.
What documentation supports reporting 77301?
Keep the IMRT plan and records supporting its optimization, target and critical-structure dose evaluation, prescribed dose, and physician approval.
How does 77338 relate to 77301?
Code 77338 reports design of an IMRT multileaf collimator device and is an add-on to 77301 when that device-design service is performed.
Where these rates come from
