About BG33YZZ

BG33YZZ is the ICD-10-PCS code for a magnetic resonance imaging (MRI) procedure on the parathyroid glands using an other contrast 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 other and unspecified sites, the ICD-9-CM procedure title it maps to (88.97).

For a different body part, codes include BG32YZZ (bilateral adrenal glands) and BG34YZZ (thyroid gland).

The same procedure with a different approach is coded BG33ZZZ (none).

With a different device, use BG33Y0Z (unenhanced and enhanced).

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.
