About 77011: CT-guided stereotactic localization
Reports CT guidance used to localize a target stereotactically, such as for planning a stereotactic radiosurgery procedure.
This service uses computed tomography to establish stereotactic coordinates for a target, rather than to guide a needle or monitor tissue ablation. A typical use is localizing an intracranial target for stereotactic radiosurgery. The service may be performed in a hospital or imaging setting by a radiologist or a radiation oncology team, with technical staff acquiring the CT images and a qualified clinician interpreting them.
Report 77011 when the documented purpose of the CT is stereotactic localization. The record should identify the target, the stereotactic purpose, and the imaging and interpretation supporting that service. CMS recognizes a professional component, reported with modifier 26, and a technical component, reported with modifier TC; a claim without either modifier represents the global service. The professional component covers interpretation, while the technical component covers equipment and staff. Do not select this code merely because CT images were obtained during another image-guided procedure; distinguish stereotactic localization from CT-guided needle placement or ablation.

77011 billing questions
How is 77011 different from CT-guided needle placement?
77011 is for CT used to establish stereotactic localization. Use 77012 when CT guides needle placement, such as for a biopsy, aspiration, injection, or localization device.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the professional interpretation or modifier TC for the technical service. Billing without either modifier represents the global service.
What documentation supports 77011?
Document the target, the stereotactic localization purpose, and the CT guidance and interpretation performed. The record should make clear that the service was not simply CT guidance for a needle procedure or ablation.
Is 77011 the code for CT-guided tissue ablation?
No. 77013 describes CT guidance and monitoring for percutaneous ablation; 77011 is for stereotactic localization.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
