Summary & Overview
CPT 77262: Detailed Radiation Therapy Treatment Planning
CPT code 77262 represents a detailed radiation therapy treatment planning service in which the provider defines beam entry points (ports), number and placement of ports, shielding block design and placement, and selects modes of therapy such as arc therapy or brachytherapy. This code matters nationally because precise treatment planning is central to effective, safe radiation oncology care and affects treatment quality, resource use, and billing consistency across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a compact overview of the code’s clinical context and common sites of service, as well as what typical analyses address: utilization benchmarks, payer policy coverage considerations, and coding alignment with clinical workflow. The publication also outlines common modifier usage and highlights where data is not available in the input.
This summary provides clinicians, coders, and policy analysts with the operational meaning of CPT code 77262, the service settings where it is typically performed, and the scope of topics covered in the full publication — including benchmarks, payer policy summaries, and clinical implications for radiation oncology treatment planning.
Billing Code Overview
CPT code 77262 describes the radiation therapy treatment planning process in which the provider determines the entry points (ports) for radiation beams, the number and placement of those ports, the design and placement of shielding blocks, and the selection of therapy modes (for example, arc therapy or brachytherapy). The planning may specify a single mode of therapy or a combination of modes.
-
Service type: Radiation therapy treatment planning, detailed planning of beam geometry and shielding
-
Typical site of service: Radiation oncology clinic, hospital radiation therapy department, or outpatient cancer treatment center

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a confirmed localized prostate adenocarcinoma is evaluated for external beam radiation therapy planning. The radiation oncologist performs a detailed planning session to determine beam entry points (ports), number of fields, use and placement of shielding blocks, beam energies, and whether to employ arc therapy or brachytherapy components. The workflow includes review of diagnostic imaging (CT simulation, possibly fused MRI), delineation of target volumes and organs at risk, calculation of beam arrangements, selection of immobilization and positioning devices, and documentation of the plan parameters and rationale. The planning encounter addresses single-modality external beam therapy or a combination approach (e.g., external beam boost with brachytherapy), and results in a written plan for daily treatment delivery.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician's interpretation/planning component separate from technical delivery or equipment. |
50 | Bilateral procedure | Use if identical planning is performed for bilateral target sites in a single session and payer recognizes bilateral modifier for planning codes. |
