About the BQ3 Code Range

MRI uses a magnetic field and radiofrequency signals to make computer-displayed images. These images show the hip, femur (thigh bone), knee, lower leg, ankle, calcaneus (heel bone), foot, toes, or patella (kneecap).

The fourth character identifies the body part and its right or left side. The fifth records Other Contrast or None. The sixth qualifier is Unenhanced and Enhanced or None; the seventh is always None.

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, 2026 through September 30, 2027. 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.
