CPT® Code 77525

1. Indications

The procedure described by CPT® Code 77525 is indicated for the treatment of various types of tumors, particularly those that are located beneath significant amounts of healthy tissue. The following conditions may warrant the use of complex proton treatment delivery:

• Deep-seated tumors Tumors that are situated deep within the body, where traditional radiation therapy may pose a higher risk of damaging surrounding healthy tissues.
• Specific cancer types Certain cancers, such as pediatric tumors, brain tumors, and prostate cancer, may benefit from the precision of proton therapy.
• Recurrent tumors Tumors that have recurred after previous treatments may be targeted effectively with proton therapy to minimize further damage to healthy tissue.

2. Procedure

The procedure for complex proton treatment delivery involves several critical steps to ensure effective targeting of the tumor while protecting surrounding healthy tissue. The following outlines the procedural steps:

• Step 1: Patient Preparation The patient is positioned on the treatment table, and imaging studies may be performed to accurately locate the tumor. This positioning is crucial for ensuring that the proton beam is directed precisely at the tumor site.
• Step 2: Treatment Planning A detailed treatment plan is developed, which includes determining the appropriate energy levels of the proton beam, the number of treatment areas, and the configuration of ports. This plan is tailored to the individual patient's anatomy and the specific characteristics of the tumor.
• Step 3: Delivery of Proton Beam The physician administers the proton beam therapy, utilizing two or more ports per treatment area. The treatment may involve matching or patching fields and/or multiple isocenters to ensure comprehensive coverage of the tumor while minimizing exposure to healthy tissues.
• Step 4: Use of Custom Blocks and Compensators During the treatment, custom blocks and compensators are employed to shape the proton beam according to the tumor's contours. This customization enhances the precision of the treatment, allowing for optimal targeting of the tumor.

3. Post-Procedure

After the completion of the proton treatment delivery, patients may be monitored for any immediate side effects or reactions to the therapy. Post-procedure care typically includes follow-up appointments to assess the effectiveness of the treatment and to monitor for any potential complications. Patients may also receive guidance on managing any side effects that may arise, as well as recommendations for ongoing care and support. The recovery process may vary depending on the individual patient's condition and the extent of the treatment received.
