About 77021: MRI-guided needle placement
MRI guidance supports real-time needle positioning during a percutaneous procedure when MRI is the selected imaging method and guidance is separately reportable.
This service covers MRI imaging used to direct needle placement during a percutaneous procedure, such as a biopsy, aspiration, or injection. The radiologist or other qualified imaging professional monitors the needle’s position and provides the imaging supervision and interpretation; the procedural clinician performs the intervention. It is typically furnished in an MRI suite when the target or approach calls for MRI guidance rather than CT, fluoroscopy, or another modality.
Select this code based on the imaging method and the service performed, not simply because an MRI was obtained. Documentation should identify the target, the needle-guidance procedure, and the imaging supervision and interpretation. Report it with the related procedure only when that procedure’s code does not already include the same guidance. CMS recognizes professional and technical components: modifier 26 reports the interpretation, modifier TC reports the equipment and staff, and no modifier represents the global service.

77021 billing questions
How does 77021 differ from CT-guided needle placement?
77021 is for MRI guidance. Use a CT guidance code, such as 77012 for needle biopsy guidance, when CT is the imaging method.
Can 77021 be reported with an MRI-guided breast biopsy?
Breast biopsy codes such as 19085 include MRI guidance for the first lesion. Do not separately report 77021 for guidance already included in the biopsy service.
Which modifiers report the components?
Use modifier 26 for the professional interpretation and modifier TC for the technical component. Billing without either modifier represents the global service.
Does 77021 describe the biopsy or injection itself?
No. It reports MRI guidance for needle placement and the associated imaging supervision and interpretation; the biopsy, aspiration, or injection is represented by its own procedure code.
How should documentation support 77021?
Document the target and percutaneous procedure, the use of MRI to guide needle placement, and the imaging supervision and interpretation. Check that the associated procedure code does not already include that guidance.
Is 77021 interchangeable with MRI ablation guidance?
No. 77021 addresses MRI guidance for needle placement; 77022 is used for MRI guidance of parenchymal tissue ablation.
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.
