Detailed Description of CPT Code 55874
CPT Code: 55874
• Code Description: Insertion of biocompatible marker or spacer (e.g., prostate‐rectal spacer) for radiation therapy guidance
• Inclusions: Transperineal placement of spacer, use of imaging (e.g., ultrasound/CT) for guidance, local anesthesia, post-placement confirmation imaging
• Exclusions: Removal of spacer, fiducial marker placement without spacer, separate anesthesia services, radiation treatment sessions
Coding & Billing Considerations
• Report only once per treatment course, not per fraction of radiotherapy.
• Append modifier 59 to indicate distinct procedure from radiation therapy if required.
• Include documentation of imaging guidance (US or CT) and anesthesia used.
• Verify spacer type (e.g., hydrogel) in operative note.
• Do not report 55874 with codes for fiducial marker placement alone.
• Ensure payer preauthorization when required for hydrogel placement.
Why Proper Coding Is Important
Accurate reporting of CPT code 55874 ensures appropriate reimbursement and supports quality documentation in radiation oncology. Proper coding avoids denials and clarifies that the spacer placement is separate from the radiation treatment. It also contributes to compliance with payer guidelines and supports effective clinical communication.
What is a CPT Code?
CPT stands for Current Procedural Terminology. These codes are used by medical professionals to describe procedures and services performed. CPT codes are crucial for the billing process, allowing healthcare providers to communicate with insurance companies and other payers about the procedures performed.
