About BW33YZZ
BW33YZZ is the ICD-10-PCS code for a magnetic resonance imaging (MRI) procedure on the chest 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 chest and myocardium and other intraoperative magnetic resonance imaging, the ICD-9-CM procedure titles it maps to (88.92 and 88.96).
For a different body part, codes include BW30YZZ (abdomen), BW38YZZ (head), BW3FYZZ (neck), BW3GYZZ (pelvic region), BW3HYZZ (retroperitoneum) and BW3PYZZ (brachial plexus).
With a different device, use BW33Y0Z (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.

Common questions about BW33YZZ
Is BW33YZZ a valid ICD-10-PCS code for 2027?
- Yes. BW33YZZ is valid for inpatient procedures from October 1, 2026 through September 30, 2027.
What is the ICD-9 procedure code for BW33YZZ?
- The CMS GEMs map BW33YZZ to ICD-9-CM 88.92 (Magnetic resonance imaging of chest and myocardium) and 88.96 (Other intraoperative magnetic resonance imaging).
