About the BL3 Code Range

These MRI procedures create computer-displayed images of connective tissue and tendons in the arms or legs using a magnetic field and radiofrequency signals.

The fourth character distinguishes connective tissue from tendons and the upper from the lower extremity. The fifth character records Other Contrast or None. The sixth records Unenhanced and Enhanced or None; the seventh is always None.

Questions About This Page

How many billable codes are in the BL3 range?

Of the 13 codes in this range, 12 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 BL3 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 connective tissue. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
