ICD-10-PCS B23 Imaging: Heart Magnetic Resonance Imaging (MRI)

The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (B23) refers to producing detailed images of body parts using magnetic resonance technology. This operation belongs to the Imaging section and is instrumental for noninvasively visualizing internal anatomy.

Within this classification, MRI of the Heart is specifically coded to reflect various targets and contrast usage. For example, codes such as B231ZZZ and B233ZZZ denote MRI procedures of Multiple Coronary Arteries and Multiple Coronary Artery Bypass Grafts, respectively, without contrast enhancement. Meanwhile, codes like B231Y0Z and B233Y0Z specify MRIs with other contrast agents, either unenhanced or enhanced. Additionally, MRI of the Right and Left Heart is captured by codes such as B236ZZZ and B236Y0Z, depending on contrast use. These distinctions enable precise documentation of cardiac MRI studies, supporting accurate reporting and clinical correlation.

List of ICD-10-PCS codes used to specify B23 - Magnetic Resonance Imaging (MRI) (computer reformatted digital display of multiplanar images developed from the capture of radio frequency signals emitted by nuclei in a body site excited within a magnetic field). There are a total of 10 procedure codes in this section.
