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

What 77046 covers

This code covers MRI imaging of one breast performed without contrast. A common use is evaluating a breast implant for possible rupture or other integrity concerns. A technologist typically acquires the images in an outpatient imaging center or hospital, and a radiologist interprets them. The code is specific to a unilateral, noncontrast examination; it does not describe a contrast-enhanced breast MRI protocol.

Select the code when the documented examination covers one breast and uses no contrast. The order, imaging record, laterality, protocol, and radiologist’s report should support those details and the clinical indication. CMS recognizes separate professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and billing without either modifier represents the global service. The diagnostic imaging multiple procedure reduction applies to both the technical and professional components.
