Cardiac imaging
About 93356: Myocardial strain imaging by speckle tracking
Reports echocardiographic speckle-tracking analysis of myocardial deformation, commonly added to a qualifying echocardiogram when strain measurements are obtained and interpreted.
This service analyzes echocardiographic images with speckle-tracking software to assess how the heart muscle deforms during the cardiac cycle, including measurements such as longitudinal strain. Cardiologists may use the results when evaluating cardiomyopathy, suspected cardiac amyloidosis, or changes in cardiac function during potentially cardiotoxic treatment. A sonographer typically acquires the images, and a qualified physician interprets the strain findings and includes them in the report.
Report 93356 only with an eligible primary echocardiography procedure; it is not a stand-alone service. The record should support that speckle-tracking strain analysis was performed and interpreted, with the findings documented alongside the primary echocardiogram. CMS treats this as an add-on paid within the primary procedure’s global period. The strain analysis is distinct from the standard measurements and Doppler components of an echocardiogram, so the report should make clear that myocardial strain imaging was performed.

93356 billing questions
Can 93356 be billed by itself?
No. It is an add-on and must be reported with an eligible primary echocardiography procedure.
Is 93356 included in a complete transthoracic echocardiogram?
The code represents a separate speckle-tracking strain analysis, not the standard measurements of a complete echocardiogram. Report it only when that analysis is performed and interpreted.
What documentation supports reporting 93356?
The echocardiography record should show that speckle-tracking strain analysis was performed, and the interpreting report should document the strain findings.
Does 93356 replace Doppler imaging?
No. Speckle-tracking strain analysis assesses myocardial deformation; it is distinct from Doppler evaluation of blood flow.
How is 93356 paid in relation to the primary echocardiogram?
CMS classifies it as an add-on and pays it within the primary procedure’s global period. It must be billed together with the primary procedure.
