Billing tips

Bill 77014 only once per radiation therapy treatment course, not per fraction or daily treatment
Impact: Prevents automatic denials and recoupment; multiple billings can trigger $115.80+ overpayment recovery per incorrect claim
Document the specific radiation therapy planning purpose in the radiology report, linking CT findings to treatment field design
Impact: Reduces denial rate by 60-70% when medical necessity is clearly established in documentation
Verify that 77014 is not already included in the global radiation oncology treatment planning code (77295, 77301, 77306, 77307) before billing separately
Impact: Prevents unbundling edits and denials; bundled services result in zero additional payment and potential compliance review
For split billing scenarios, ensure modifier 26 or TC is appended and coordinate with the facility to avoid duplicate billing
Impact: Prevents overpayment flags; combined 26/TC without coordination can result in 200% payment and subsequent recoupment
Link 77014 to appropriate oncology diagnosis codes (typically C00-D49 range) and include laterality when applicable
Impact: Improves first-pass claim acceptance by 40-50%; missing laterality can delay payment 15-30 days
When billing with stereotactic radiosurgery codes (77371-77373), ensure 77014 is performed on a different date or append modifier 59 with clear documentation
Impact: Overcomes NCCI edits that would otherwise deny the $115.80 payment as bundled

How many times can you bill 77014 during a radiation therapy course?

Medicare typically allows 77014 once per radiation therapy treatment course. Additional billing requires documented medical necessity such as significant anatomic changes, tumor progression requiring re-planning, or treatment field modification with new CT guidance.

What is the difference between CPT 77014 and a diagnostic CT scan?

CPT 77014 is specifically for CT imaging used to guide radiation therapy planning and simulation, with images integrated into treatment planning systems. Diagnostic CT scans use different codes (70000-74190 series) and are performed for diagnostic purposes. The intent and use of the images determine correct coding.

Do I need modifier 26 or TC when billing CPT 77014?

Use modifier 26 for professional component only (physician supervision and interpretation) or modifier TC for technical component only (equipment and technologist). In hospital settings, the facility typically bills TC while the physician bills 26. Omit modifiers only when billing the global service in non-facility settings.
