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.

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.
