What 77022 covers
This service covers MRI used during an ablation procedure to help direct the treatment device into organ tissue and monitor the treated area. It may be used for image-guided ablation of a tumor in parenchymal tissue, such as liver or kidney tissue. A radiologist or interventional radiologist typically performs or interprets the imaging in a hospital or other setting equipped for MRI-guided intervention. The ablation itself is a distinct therapeutic service.
Medicare assigns this CPT code physician fee schedule status C, or carrier priced: the Medicare Administrative Contractor sets payment for each claim rather than CMS publishing a national amount. The code has professional and technical portions. Modifier 26 identifies the interpretation; modifier TC identifies the equipment and staff portion. Without either modifier, the code represents the global service. Report the imaging guidance and monitoring separately from the applicable ablation procedure when both services are performed.

77022 billing questions
When should this code be chosen instead of 77021?
Use this code for MRI guidance and monitoring during parenchymal tissue ablation. Code 77021 is for MRI guidance used for needle placement, not ablation monitoring.
Is the tissue ablation itself included?
No. This code describes the MRI guidance and monitoring service; report the applicable ablation procedure separately when performed.
How do modifiers 26 and TC apply?
Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion. Without either modifier, the code represents the global service.
How does Medicare price this code?
Its physician fee schedule status is C, or carrier priced. The Medicare Administrative Contractor sets payment for each claim.
