BG3 Magnetic Resonance Imaging (MRI) - Endocrine System ICD-10-PCS
The BG3 code range contains 10 ICD-10-PCS codes for Magnetic Resonance Imaging (MRI) procedures on the endocrine system. 9 of the codes are billable and valid for inpatient claim submission in fiscal year 2027.
Root Operation Definition
Magnetic Resonance Imaging (MRI): Computer reformatted digital display of multiplanar imagesdeveloped from the capture of radiofrequency signals emitted by nuclei in a body site excitedwithin a magnetic field.

About the BG3 Code Range
These MRI scans use a magnetic field and radiofrequency signals to make images of both adrenal glands, the parathyroid glands, or the thyroid gland.
The fourth character identifies the body part. The fifth 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 BG3 range?
Of the 10 codes in this range, 9 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 BG3 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 endocrine system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
