How To Use CPT Code 77307

CPT 77307 describes the process of teletherapy isodose planning for external beam radiation therapy. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 77307?

CPT 77307 can be used to describe the teletherapy isodose planning performed by a provider for external beam radiation therapy. This code is used when the provider arranges tangential ports and calculates the appropriate dose based on the type and stage of the cancer being treated.

2. Official Description

The official description of CPT code 77307 is: ‘Teletherapy isodose plan; complex (multiple treatment areas, tangential ports, the use of wedges, blocking, rotational beam, or special beam considerations), includes basic dosimetry calculation(s).’ It is important to note that only one teletherapy isodose plan can be reported for a given course of therapy to a specific treatment area, and this code should not be reported in conjunction with CPT code 77300.

3. Procedure

1. The provider performs teletherapy isodose planning, either by hand or by computer calculation.
2. Lines are plotted to achieve equal intensity of radiation dose to the treatment field.
3. The provider calculates the appropriate dose and method of radiation therapy based on the type and stage of the cancer being treated.
4. Various factors are considered to determine the optimal angle to place the port and ensure equal intensity of radiation distribution over the treatment area.
5. Tangential ports may be used to target a common treatment area, and wedges, blocks, or rotational beam may be utilized to modify the radiation beam if necessary.

4. Qualifying circumstances

CPT 77307 is used for teletherapy isodose planning in cases where multiple treatment areas are involved, tangential ports are used, wedges, blocking, rotational beam, or special beam considerations are required. The complexity of the treatment plan and the use of these additional techniques qualify for the use of CPT 77307.

5. When to use CPT code 77307

CPT code 77307 should be used when the teletherapy isodose planning involves multiple treatment areas, tangential ports, and the use of wedges, blocking, rotational beam, or special beam considerations. It should not be used for treatment that involves one or two parallel opposing ports, which would be reported with CPT code 77306.

6. Documentation requirements

To support a claim for CPT 77307, the provider must document the following information:

• Type and stage of the cancer being treated
• Calculation of the appropriate dose and method of radiation therapy
• Factors considered in determining the optimal angle and placement of the port
• Details of any additional techniques used, such as wedges, blocking, rotational beam, or special beam considerations
• Documentation of the teletherapy isodose plan, including the lines plotted to achieve equal intensity of radiation dose
• Signature of the provider performing the teletherapy isodose planning

7. Billing guidelines

When billing for CPT 77307, ensure that the teletherapy isodose planning involves multiple treatment areas, tangential ports, and the use of wedges, blocking, rotational beam, or special beam considerations. Do not report CPT 77307 in conjunction with CPT code 77300. It is important to note that CPT code 77307 includes the calculation of dose, so do not report code 73000 for basic radiation dosimetry calculations.

8. Historical information

CPT 77307 was added to the Current Procedural Terminology system on January 1, 2015. There have been no updates to the code since its addition.

9. Examples

1. A provider performing teletherapy isodose planning for a patient with breast cancer involving multiple treatment areas, tangential ports, and the use of wedges to achieve optimal radiation distribution.
2. A provider calculating the appropriate dose and method of radiation therapy for a patient with lung cancer, considering the complexity of the treatment plan and using rotational beam to target the tumor.
3. A provider using teletherapy isodose planning to treat a patient with head and neck cancer, utilizing special beam considerations to ensure equal intensity of radiation dose to the treatment field.
4. A provider performing teletherapy isodose planning for a patient with prostate cancer, using blocking techniques to protect surrounding tissues while delivering the appropriate dose to the tumor.
5. A provider using teletherapy isodose planning to treat a patient with brain cancer, employing multiple treatment areas and tangential ports to target the tumor from different angles.
6. A provider calculating the appropriate dose and method of radiation therapy for a patient with cervical cancer, considering the complexity of the treatment plan and using wedges to modify the radiation beam.
7. A provider performing teletherapy isodose planning for a patient with colorectal cancer, utilizing rotational beam and special beam considerations to achieve optimal radiation distribution.
8. A provider using teletherapy isodose planning to treat a patient with lymphoma, employing multiple treatment areas and tangential ports to target the affected lymph nodes.
9. A provider calculating the appropriate dose and method of radiation therapy for a patient with pancreatic cancer, considering the complexity of the treatment plan and using blocking techniques to protect surrounding organs.
