About the BH3 Code Range

MRI captures radio signals from a body site in a magnetic field to create computer images in multiple planes. Here, it images the breasts or tissue beneath the skin.

The fourth character identifies the right breast, left breast or both breasts, or tissue beneath the skin in a named body region. Those regions are the head and neck, upper extremity, thorax, abdomen and pelvis, and lower extremity. The fifth character 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 BH3 range?

Of the 25 codes in this range, 24 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 BH3 range classify?

The range classifies Magnetic Resonance Imaging (MRI) procedures, computer reformatted digital display of multiplanar imagesdeveloped from the capture of radiofrequency signals emitted by nuclei in a body site excitedwithin a magnetic field, performed on the skin, subcutaneous tissue and breast. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
