About BB34Z3Z

BB34Z3Z is the ICD-10-PCS code for a magnetic resonance imaging (MRI) procedure on the bilateral lungs using a none approach with hyperpolarized xenon 129 (xe-129) (qualifier: none). In ICD-10-PCS, magnetic resonance imaging (MRI) means computer reformatted digital display of multiplanar images developed from the capture of radiofrequency signals emitted by nuclei in a body site excited within a magnetic field.

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2023, effective October 1, 2022.
