B93 Magnetic Resonance Imaging (MRI) - Ear, Nose, Mouth and Throat ICD-10-PCS
The B93 code range contains 22 ICD-10-PCS codes for Magnetic Resonance Imaging (MRI) procedures on the ear, nose, mouth and throat. 21 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 B93 Code Range
Magnetic resonance imaging (MRI) uses a magnetic field and radio signals to create images of ear, nose, mouth and throat sites in multiple planes.
The fourth character identifies the ear, paranasal sinuses, bilateral parotid glands, bilateral submandibular glands, bilateral salivary glands, nasopharynx/oropharynx, or larynx. The fifth character records Other Contrast or None. The sixth records Unenhanced and Enhanced or None, and the seventh is always None.
Questions About This Page
How many billable codes are in the B93 range?
Of the 22 codes in this range, 21 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 B93 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 ear, nose, mouth and throat. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
