Radiology Question for the Week of June 19, 2023


We have been following the instruction that 75774 only applies to subselective ARTERIAL studies; however, CPT® Assistant September 2022 states “If venography is performed in a main vessel and then a selective venogram is performed, report code 75774 in addition to the venography code for the initial vessel. Can you please clarify any current instructions?


As of the publishing of CPT Assistant Sept 2022 Question and Answers, CPT 75774 Angiography, selective, each additional vessel studied after basic examination, radiological supervision, and interpretation (List separately in addition to code for primary procedure), may be used to capture additional selective venographic studies after a base venographic service is performed. An example of this could include a study of the external iliac vein, followed by a more selective study of the internal iliac vein. The external iliac venography is captured with CPT 75820, and the additional more selective study of the internal iliac vein is captured with 75774. Make sure that 75774 is used for medically necessary, selective, or supra-selective studies after a base study is performed. In the situation when the only venographic service rendered is of a vein that does not have a named vessel venography code, do not use 75774 to capture that service, and instead use CPT 76496 -Unlisted fluoroscopic procedure (eg, diagnostic, interventional). An example of this is a study of the uterine vein, with no other additional venography services rendered. This would be coded with 76496.
