Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 70557 covers

This code represents an MRI examination of the brain performed without contrast material. Hospital imaging departments and independent imaging centers provide the scan; a radiologist typically interprets the images and prepares a report for the ordering clinician. The study can be used to evaluate neurologic symptoms or suspected brain abnormalities when the examination is performed without contrast.

Medicare assigns physician fee schedule status C: there is no national payment amount, and the Medicare Administrative Contractor sets payment for each claim. The diagnostic test has professional and technical components. Report modifier 26 for the interpretation, modifier TC for the equipment and staff, or no component modifier when billing the global service. Report the contrast-specific brain MRI code when contrast is used, or when both noncontrast and contrast imaging are performed.

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.
