How To Use CPT Code 77261

CPT 77261 describes the process of clinical treatment planning for radiation treatment using external and internal sources. This article will cover the description, official definition, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 77261?

CPT 77261 involves the clinical treatment planning for radiation treatment using external and internal sources. It is a code used to describe the process of determining the dosage, method, and duration of radiation therapy for cancerous tumors. The treatment plan takes into consideration the size and location of the tumor, aiming to destroy the malignant cells while minimizing damage to surrounding healthy tissues and organs.

2. Official Description

The official description of CPT code 77261 is: ‘Therapeutic radiology treatment planning; simple.’ This code is used for straightforward treatment planning of a tumor in a single area, which requires minimal or no blocking and can be encompassed with simple portal arrangements.

3. Procedure

1. The provider determines the location and number of ports for radiation beams to enter the body.
2. The design and location of shielding blocks are decided to protect healthy tissues.
3. The treatment plan may involve using a single mode or a combination of different modes of therapy, such as arc therapy or brachytherapy.
4. Simple treatment planning is performed for superficial orthovoltage, cobalt, linear accelerator, or photon treatments of a defined treatment area.
5. No interpretation of special tests for tumor localization is required, and the volume of interest can be encompassed with simple portal arrangements.

4. Qualifying circumstances

CPT 77261 is used for treatment planning of a tumor in a single area that requires straightforward planning with minimal or no blocking. It does not involve complex blocking, custom shielding blocks, brachytherapy simulation, or interpretation of special tests for tumor localization. The treatment area can be treated with superficial orthovoltage, cobalt, linear accelerator, or photon services.

5. When to use CPT code 77261

CPT code 77261 should be used when the treatment planning involves a single treatment area and is straightforward, without the need for complex blocking or interpretation of special tests. It is appropriate for superficial orthovoltage, cobalt, linear accelerator, or photon treatments. If the treatment planning involves two separate treatment areas or requires complex blocking, a different code should be used.

6. Documentation requirements

To support a claim for CPT 77261, the following documentation is required:

• Clear indication of the treatment area and the need for radiation therapy
• Details of the treatment plan, including the location and number of ports, design and location of shielding blocks
• Confirmation that the treatment plan is simple and does not involve complex blocking or interpretation of special tests
• Documentation of the treatment area being encompassed with simple portal arrangements
• Signature of the provider responsible for the treatment planning

7. Billing guidelines

When billing for CPT 77261, ensure that the treatment planning is straightforward and does not involve complex blocking or interpretation of special tests. It is important to accurately document the treatment area and the simplicity of the treatment plan. CPT code 77261 should not be reported with other codes unless the circumstances meet the criteria for a more complex treatment planning.

8. Historical information

CPT 77261 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates or changes to the code since its addition.

9. Examples

1. A patient with a superficial skin tumor receiving radiation treatment using orthovoltage therapy.
2. A patient with a single breast tumor undergoing radiation treatment using cobalt therapy.
3. A patient with a localized tumor in the lung receiving radiation treatment using linear accelerator therapy.
4. A patient with a tumor in the head and neck region undergoing radiation treatment using photon therapy.
5. A patient with a tumor in the pelvis receiving radiation treatment using brachytherapy.
6. A patient with a tumor in the abdomen undergoing radiation treatment using arc therapy.
7. A patient with a tumor in the spine receiving radiation treatment using cobalt therapy.
8. A patient with a tumor in the extremity undergoing radiation treatment using orthovoltage therapy.
9. A patient with a tumor in the brain receiving radiation treatment using linear accelerator therapy.
10. A patient with a tumor in the chest region undergoing radiation treatment using photon therapy.
