What 70554 covers

This service uses functional MRI to map brain activity associated with tasks, often to help plan surgery near areas involved in language or movement. A technologist conducts the imaging acquisition; the physician or psychologist interprets the study and prepares the report without attending the acquisition. It is commonly performed in a hospital or imaging center when a clinical team needs functional information for neurologic or neurosurgical evaluation.

Choose this code for functional rather than routine anatomic brain imaging, and retain documentation of the clinical purpose, acquisition, interpretation, and report. The global service is billed without a component modifier; modifier TC identifies the technical service, and modifier 26 identifies the professional interpretation. When multiple diagnostic imaging procedures are performed, the imaging multiple-procedure reduction applies to both components. CMS pays each side separately at 100% when the service is performed bilaterally.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

70554 billing questions

How is 70554 different from 70555?

70554 is for technologist acquisition without physician or psychologist attendance. Use 70555 when the physician or psychologist attends the functional imaging.

Can the technical and professional services be billed separately?

Yes. Report modifier TC for the technical service and modifier 26 for the professional interpretation and report. Billing without either modifier represents the global service.

When does the imaging multiple-procedure reduction apply?

When multiple diagnostic imaging procedures are performed, CMS applies the reduction to both the technical and professional components.

Is 70554 the code for a routine brain MRI?

No. It describes functional imaging that maps task-related brain activity. Routine anatomic brain MRI is represented by codes such as 70551 through 70553, selected according to contrast use.

What documentation supports reporting 70554?

Document the clinical reason for functional mapping, the imaging acquisition, and the interpreting physician's or psychologist's findings and report. The record should support that the technologist performed the acquisition without physician or psychologist attendance.

How does CMS treat bilateral performance?

When the service is performed bilaterally, CMS pays each side separately at 100%. Follow applicable claim instructions for reporting the sides.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
