B03 Magnetic Resonance Imaging (MRI) - Central Nervous System ICD-10-PCS
The B03 code range contains 13 ICD-10-PCS codes for Magnetic Resonance Imaging (MRI) procedures on the central nervous system. 12 of the codes are billable and valid for inpatient claim submission in fiscal year 2027.
Root Operation Definition
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.

About the B03 Code Range
Magnetic resonance imaging (MRI) uses a magnetic field and radiofrequency signals to make digital images of central nervous system sites.
The fourth character identifies the brain, sella turcica/pituitary gland, spinal cord, or acoustic nerves. The fifth records Other Contrast or None. The sixth distinguishes Unenhanced and Enhanced from None, while the seventh is always None.
The Index also directs myelogram to this table.
Questions About This Page
How many billable codes are in the B03 range?
Of the 13 codes in this range, 12 are billable and valid for inpatient claim submission from October 1, 2026 through September 30, 2027. Table header codes group them but cannot be reported on claims.
What does the B03 range classify?
The range classifies Magnetic Resonance Imaging (MRI) procedures, 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, performed on the central nervous system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
