About BN39ZZZ

BN39ZZZ is the ICD-10-PCS code for a magnetic resonance imaging (MRI) procedure on the bilateral temporomandibular joints using a none approach with none (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.

In plain terms, this corresponds to magnetic resonance imaging of musculoskeletal, the ICD-9-CM procedure title it maps to (88.94).

The same procedure with a different approach is coded BN39YZZ (other contrast).

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

It has been valid since ICD-10-PCS took effect on October 1, 2015.
