Frequently Asked Questions
CPT 77387 reports guidance for localizing the target volume during radiation treatment delivery (image guided radiation therapy), including intrafraction tracking when performed.
Medicare has used separate HCPCS codes for the technical side of image guidance in some settings, so commercial and Medicare claims for the same service can use different codes. Check which component and setting a rate applies to before comparing.
Imaging codes such as CPT 77387 split into a professional component (modifier 26, the physician's interpretation) and a technical component (modifier TC, the equipment, staff and supplies). A global claim covers both. A radiologist reading for a hospital usually bills only the professional component, so compare rates for the same component. Commercial rates also differ between hospital outpatient departments and freestanding imaging centers.
This page lists the rates commercial payers have published for CPT 77387 in their Transparency in Coverage files, so you can compare payers and see where a contract falls. For government benchmarks, PayerPrice also has the Medicare fee schedule lookup and Medicaid fee schedules by state.
