ICD-10 Code
International Classification of Diseases, 10th Revision

Procedure Terms used in “Imaging”

Imaging procedure codes have a first character value of “B”. Imaging section codes represent procedures including plain radiography, fluoroscopy, CT, MRI, and ultrasound. Nuclear medicine procedure codes, including PET, uptakes, and scans, are in the nuclear medicine section. Therapeutic radiation procedure codes are in a separate radiation oncology section.

In the imaging section, the second character defines the body system and the fourth character defines the body part. The third character defines the root type of imaging procedure (e.g, MRI, ultrasound).

The fifth character specifies whether the contrast material used in the imaging procedure is high or low osmolar, when applicable. The sixth character qualifier provides further detail as needed, such as unenhanced followed by enhanced. The seventh character qualifier contains specific values as needed to further specify the objective of the imaging procedure, e.g., densitometry, or the approach used, e.g., intravascular.


Terms for Imaging

Computerized Tomography (CT Scan)
Computer reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation
Fluoroscopy
Single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means
Magnetic Resonance Imaging (MRI)
Computer reformatted digital display of multiplanar images developed from the capture of radiofrequency signals emitted by nuclei in a body site excited within a magnetic field
Plain Radiography
Planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate
Ultrasonography
Real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves

When ICD 10 was implemented on October 1, 2015, it did not affect physicians', outpatient facilities', and hospital outpatient departments' use of CPT codes on Medicare Fee-For-Service claims. Providers should continue to use CPT codes to report these services.
