BB3 Magnetic Resonance Imaging (MRI) - Respiratory System ICD-10-PCS
The BB3 code range contains 5 ICD-10-PCS codes for Magnetic Resonance Imaging (MRI) procedures on the respiratory system. 4 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 BB3 Code Range
MRI creates digital images of both lungs or the lung apices from radiofrequency signals captured in a magnetic field.
The fourth character distinguishes both lungs from the lung apices. The fifth records Other Contrast or None. The sixth specifies Unenhanced and Enhanced, Hyperpolarized Xenon 129 (Xe-129), or None. The seventh is always None.
Questions About This Page
How many billable codes are in the BB3 range?
Of the 5 codes in this range, 4 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 BB3 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 respiratory system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
