About the B93 Code Range
The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (code prefix B93) refers to using MRI technology to create detailed images of body parts, specifically within the Ear, Nose, Mouth, and Throat area according to the Imaging section classification.
This operation captures cross-sectional images that help visualize anatomical structures and diagnose conditions without the use of ionizing radiation. Examples of specific uses include MRI of the Ear (codes like B930ZZZ), Paranasal Sinuses (B932ZZZ), and various glandular structures such as the Bilateral Parotid (B936ZZZ) and Submandibular Glands (B939ZZZ). Codes also distinguish procedures that employ Other Contrast, both unenhanced and enhanced, enhancing image clarity as seen in code B930Y0Z for the Ear. This granularity allows precise documentation of MRI exams performed on specific head and neck sites, providing essential information for clinical decision-making and procedural coding.
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, 2025 through September 30, 2026. 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.
