What is the CPT Code for Therapeutic Radiology Treatment Management?

Therapeutic radiology, also known as radiation therapy, is a highly technical and life-saving treatment used primarily in cancer care. However, when it comes to billing and reimbursement, radiation therapy can be complex especially if you’re not familiar with the correct CPT codes and documentation requirements. One of the most essential codes in this field is CPT 77427, which specifically addresses radiation treatment management.

CPT Code 77427:

CPT 77427 is defined as: Radiation treatment management, five treatments This code is used to bill for the professional component of care provided by a radiation oncologist during the course of five treatment sessions. It’s not billed per day, but rather once every five fractions (treatments).

What It Includes:

• Weekly evaluation of patient response
• Review of port films and imaging
• Assessment of setup and delivery accuracy
• Documentation of side effects and care adjustments
• Coordination with the medical team

For clinics and cancer centers, ensuring accurate use of 77427 is vital to maintaining revenue integrity.  Learn how Radiology Billing Services from EZ Settle Solutions can ensure accurate code usage and maximize reimbursement.
