Radiology Codes

(Including Nuclear Medicine and Diagnostic Ultrasound)

Radiology codes are one of the six sections of Category I CPT Codes and range from 70010-79999. 


Subject Listings 

Subject listings apply when radiological services are performed by or under the responsible supervision of a physician or other qualified health care professional.

Separate Procedures

Codes designated as "separate procedure" are NOT reported in addition to the code for the total procedure or service of which it is considered an integral component. 

Codes designated as "separate procedure" MAY be  reported by itself or in addition to another procedure / service by adding Modifer -59 to the "separate procedure" code IF they are carried out independently or considered unrelated or distinct. (Examples include a different session or encounter, a different procedure or surgery, different site/organ system, separate incision/excision, separate lesion, separate injury, or area of injury in extensive injuries.)

Unlisted Procedure / Service

Unlisted codes are reported for services that are not included in the CPT book. If reporting such a service, the appropriate "Unlisted Procedure" code may be used to indicate the service, identifying it as a "Special Report." 

Special Report

Some services that are new, rarely provided, variable, or unusual require a special report. These reports must include pertinent  information, including a description of the following:

  • nature, extent, & need for procedure

  • time, effort, & equipment necessary

Written Report

Written reports-- handwritten or electronic-- signed by the interpreting individual are considered an integral part of a radiological procedure.  

  • nature, extent, & need for procedure

  • time, effort, & equipment necessary

Supervision & Interpretation


Sometimes imaging is required during performances of certain procedures or certain imaging procedures may require surgical procedures so that the area may be accessed for imaging.


If imaging is NOT included in a surgical procedure or procedure from the Medicines section, image guidance codes or codes labeled "radiological supervision and interpretation" may be reported for that portion of the service.
