What 93352 covers
During a stress echocardiogram, an ultrasound-enhancing agent may be administered when standard images do not clearly show the left ventricular endocardial border. Better border definition can help the interpreting clinician assess wall motion during stress. This service is typically performed in a cardiology or hospital echocardiography setting as part of an exercise- or pharmacologic-stress study.
Report 93352 only with the primary stress echocardiography procedure, typically 93350 or 93351; it is not a stand-alone stress test or echocardiogram. Documentation should identify the stress study, the reason contrast was used, and its administration during the examination. The CMS add-on rule means payment for 93352 is made only with the primary procedure and within that procedure's global period.

93352 billing questions
Can 93352 be billed by itself?
No. It is an add-on for contrast administration during stress echocardiography and must be billed with the applicable primary stress-echo procedure, typically 93350 or 93351.
How do 93350 and 93351 differ when paired with 93352?
Select the primary code based on the stress echocardiography service performed and documented. 93352 reports the contrast administration, not the choice of stress-echo primary code.
Does 93352 report the stress echocardiogram itself?
No. It reports administration of the ultrasound-enhancing agent during the study; the stress-echo service is reported with its primary procedure code.
What should the record support for 93352?
Document the stress echocardiogram, why contrast was needed to improve image definition, and that the agent was administered during the study.
Is 93352 paid as a stand-alone service?
No. CMS treats it as an add-on payable only with its primary procedure and within that procedure's global period.
