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

What 77048 covers

This service uses magnetic resonance imaging to evaluate one breast with images acquired before and after contrast administration. A radiologic technologist performs the scan, and a radiologist interprets the images. Common diagnostic situations include assessing the extent of a known breast cancer or investigating a concerning finding that needs further evaluation. Computer-aided detection is included when performed. For imaging both breasts with and without contrast, the bilateral code is used instead.

Report 77048 for one breast, not as a unilateral substitute when the documented examination covers both breasts. The order and imaging report should support the clinical reason for the MRI, the side examined, and the use of pre- and post-contrast imaging. The global service is reported without a component modifier; modifier 26 represents the interpretation, while modifier TC represents the equipment and staff. CMS applies the diagnostic imaging multiple-procedure reduction to both the professional and technical components when it applies.
