Magnetic Resonance Imaging (MRI) of Lumbar Disc(s) using Other Contrast, Unenhanced and Enhanced

ValidICD-10-PCS procedure code.

Valid for claims with a date of service in the current code year.

Valid FY2016 onwards.

What has happened to this code

Every change the publisher made, from 2014 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

FY2014 Added to the draft code set draft Magnetic Resonance Imaging (MRI) of Lumbar Disc(s) using Other Contrast, Unenhanced and Enhanced

What this code says

Each character is read in its own position, so the same letter means different things in different places. Definitions are CMS's own.

3. Root operation Magnetic Resonance Imaging (MRI)

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
