If the physician performs injections for guidance (i.e., “road-mapping”) during coronary interventions can we report 93454?
If the physician performs injections for guidance (i.e., “road-mapping”) during coronary interventions code, 93454 is not appropriate. Remember, when the physician does not give LV angiographic data, and true diagnostic selective coronary angiography is performed and documented without crossing the aortic valve plane, code 93454 may be submitted. However, if, in addition to performing diagnostic selective coronary angiography, the physician does cross into the left ventricle (regardless of whether contrast has been injected) and records and has evidence of LV pressures being obtained, code 93458 should be submitted instead of 93454.
