What 93893 covers

93893 represents a transcranial Doppler examination directed at detecting a venous-to-arterial shunt by monitoring intracranial arterial signals. Clinicians may request it when evaluating a suspected right-to-left shunt, including during assessment of otherwise unexplained cerebral ischemia. A vascular laboratory sonographer typically acquires the Doppler data, and a qualified physician interprets the findings in an outpatient or hospital setting. The report should identify the clinical question, vessels monitored, technique, observed signals, and interpretation. A general complete or limited intracranial arterial assessment is a different service.

Select the code that matches the documented service and technique. Code 93898 specifically identifies venous-arterial shunt detection with microbubble injection, so do not assume that protocol from the 93893 descriptor alone. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and billing without a modifier represents the global service. When multiple cardiovascular diagnostic procedures are reported, the CMS multiple-procedure reduction applies to the technical component.
