What 77013 covers

77013 reports CT imaging used to guide and monitor percutaneous ablation of parenchymal tissue. During treatment, the physician uses CT images to direct the ablation instrument toward the target and monitor its position as the procedure proceeds. Interventional radiologists commonly provide or interpret this imaging in an interventional radiology or other procedural setting. The code describes imaging guidance, not the therapeutic ablation itself. It differs from CT guidance for needle placement, such as for biopsy, and from CT localization for other purposes.

Medicare assigns this code physician fee schedule status C, or carrier priced. CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The service has professional and technical components: modifier 26 identifies the professional interpretation, and modifier TC identifies the technical work, equipment, and staff. Reporting without a component modifier represents the global service.
