About the BL3 Code Range

The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (BL3) refers to using MRI techniques to produce detailed images of body structures, particularly connective tissue and tendons in this classification.

Within the Imaging section, these codes specify MRI procedures targeting connective tissues and tendons of the upper and lower extremities. For example, the code BL30ZZZ represents an MRI of Upper Extremity Connective Tissue without contrast, while BL30Y0Z documents MRI imaging using other contrast agents with both unenhanced and enhanced phases. Similarly, codes like BL32ZZZ and BL33YZZ pertain to MRIs of Upper and Lower Extremity Tendons, respectively, adding precision to describe whether contrast was used. These detailed MRI coding options enable accurate capture of imaging procedures essential for diagnosis and treatment of musculoskeletal conditions in extremities.

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, 2025 through September 30, 2026. 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.
