BT3 Magnetic Resonance Imaging (MRI) - Urinary System ICD-10-PCS
The BT3 code range contains 16 ICD-10-PCS codes for Magnetic Resonance Imaging (MRI) procedures on the urinary system. 15 of the codes are billable and valid for inpatient claim submission in fiscal year 2026.
Root Operation Definition
Magnetic Resonance Imaging (MRI): 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.

About the BT3 Code Range
The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (code BT3) refers to the use of magnetic resonance technology to produce detailed images of the urinary system's internal structures for diagnostic purposes.
This specific classification under Imaging captures MRI procedures of the urinary system, including the Bladder, Right Kidney, Left Kidney, Bilateral Kidneys, and Kidney Transplant. The coding options distinguish between imaging performed with or without the use of contrast media, including enhanced and unenhanced studies. For example, BT30Y0Z codes for MRI of the bladder using other contrast with both unenhanced and enhanced imaging, whereas BT31ZZZ represents an MRI of the right kidney without contrast. These granular distinctions aid in accurately documenting the imaging technique and target organ, essential for clinical reporting and reimbursement processes related to urinary system evaluations.
Questions About This Page
How many billable codes are in the BT3 range?
Of the 16 codes in this range, 15 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 BT3 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 urinary system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
