About the BQ3 Code Range

The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (BQ3) refers to a specialized imaging technique that uses magnetic fields and radio waves to produce detailed images of body parts. This operation is classified under the Imaging section and covers various anatomical sites, particularly non-axial lower bones.

This operation is utilized to visualize structures such as the Right and Left Hip, Femur, Knee, Lower Leg, Ankle, Calcaneus, Foot, Toe(s), and Patella with high resolution. ICD-10-PCS codes differentiate whether the MRI was performed using contrast or not, for example, BQ30Y0Z denotes an MRI of the Right Hip using Other Contrast, Unenhanced and Enhanced, while BQ30ZZZ indicates an MRI of the Right Hip without contrast use. These codes allow precise documentation of the imaging procedure performed on specific non-axial lower bone regions, supporting accurate coding and clinical communication regarding diagnostic imaging exams.

Questions About This Page

How many billable codes are in the BQ3 range?

Of the 55 codes in this range, 54 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 BQ3 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 non-axial lower bones. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
