Diagnostic Radiology CPT Codes in the ASC Setting

Diagnostic radiology covers the imaging studies that document a patient's anatomy and pathology around a surgical case. In an ASC network it usually plays a Tier-2 role: the imaging is ordered around the procedure rather than being the procedure itself. The CPT family lives in the 70000 to 79999 range and spans plain film X-ray, CT, MRI, ultrasound, and nuclear medicine, such as 72148 (MRI of the lumbar spine without contrast) and 73030 (X-ray of the shoulder).

Whether a given imaging service is separately paid in a facility setting depends on its ASC-eligibility status, and many radiology services are handled as ancillary services rather than primary listed procedures. Our dataset maps 623 ASC-relevant CPT codes to diagnostic radiology, and each code page carries the descriptor and ASC-eligibility context.

Is diagnostic imaging done in an ASC?

Imaging often supports cases performed in an ASC, but where it is captured and how it is paid depends on the service and the setting. Most outpatient diagnostic radiology is reported with place of service 11. Whether a specific imaging code is separately paid in a facility depends on its ASC-eligibility status, with many radiology services treated as ancillary services rather than as primary listed procedures.

What CPT codes does diagnostic radiology use?

Diagnostic radiology uses the CPT 70000 to 79999 range, organized by modality and body region. Examples include MRI studies such as 72148 (lumbar spine without contrast) and 73721 (lower extremity joint without contrast), plain films such as 73030 (shoulder X-ray), and contrast studies such as 70010. Our dataset maps 623 ASC-relevant radiology codes, each with its own descriptor and ASC-eligibility context.

How do I know if a radiology code is covered in an ASC?

Eligibility follows each code's ASC-eligibility status rather than the code range alone. ASC-eligible codes can be performed in a certified ambulatory surgery center. Ancillary codes support those procedures. Some codes are not typically performed in an ASC and are usually directed to a hospital outpatient department or office instead. DataLily AI's procedure library tracks CPT-specific prior-authorization and documentation requirements so you can confirm the status and the paperwork for a given study before the date of service.
