About Q0035: Cardiokymography cardiac motion study
Cardiokymography records cardiac motion as a noninvasive diagnostic study used to assess myocardial movement during evaluation of possible heart disease.
Cardiokymography is a specialized, noninvasive cardiac study that records motion associated with the beating heart. It has been used to assess regional myocardial movement, including in evaluations for possible ischemic heart disease. The service involves the recording equipment and staff needed to obtain the study, along with professional interpretation. It is distinct from an electrocardiogram, which records the heart’s electrical activity, and from echocardiography, which uses ultrasound imaging.
Report Q0035 for the cardiokymography study performed. Documentation should identify the test and clinical indication and include the recorded findings and interpretation when those services are furnished. CMS recognizes professional and technical components: use modifier 26 for the interpretation and modifier TC for the equipment and staff portion when those components are billed separately. Without a modifier, Q0035 represents the global service, including both components.
CMS billing rules for Q0035
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

Q0035 billing questions
How is Q0035 different from an electrocardiogram?
Cardiokymography records motion associated with the beating heart; an electrocardiogram records electrical activity. The tests are different modalities.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and modifier TC for the technical portion involving equipment and staff when billing those components separately.
What does Q0035 without a modifier represent?
An unmodified Q0035 represents the global service, including both the professional and technical components.
What documentation supports reporting Q0035?
Document that cardiokymography was performed, the clinical indication, and the study findings. Include the interpretation when the professional component is reported.
Is cardiokymography the same as a cardiac stress test?
No. Q0035 describes cardiokymography, a cardiac-motion recording; a stress test evaluates the heart during or after exercise or another stress protocol.
