Summary & Overview
CPT 93356: Speckle-Tracking Myocardial Strain Analysis, Echocardiography
CPT code 93356 represents speckle-tracking myocardial mechanics analysis performed in addition to standard echocardiography to quantify myocardial strain. Nationally, myocardial strain measurement is increasingly used to detect subclinical ventricular dysfunction, monitor cardiotoxicity from cancer therapies, and refine risk stratification in heart failure and valvular disease. Accurate coding and coverage interpretation for 93356 affect access to advanced cardiac imaging and the consistency of claims processing across payers.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides an overview of payer coverage landscapes, typical reimbursement benchmarks where available, and practical billing considerations for integrating strain analysis into echocardiographic service lines.
Readers will learn what CPT code 93356 covers clinically, where the service is typically provided, and how major payers approach coverage and payment for myocardial strain analysis. The report summarizes common billing modifiers and coding context, highlights potential areas of payer variability, and outlines clinical scenarios where the code is most often applied. Data not included in the input are noted as unavailable.
Billing Code Overview
CPT code 93356 describes speckle tracking of myocardial mechanics to assess myocardial strain, performed in addition to a standard echocardiographic study. This service provides quantitative assessment of myocardial deformation (strain) to aid in evaluating myocardial function beyond conventional two-dimensional and Doppler echocardiography.
-
Service type: Advanced echocardiographic myocardial strain analysis using speckle-tracking techniques
-
Typical site of service: Echocardiography laboratory or hospital-based imaging department where transthoracic echocardiography is performed

Clinical & Coding Specifications
Clinical Context
A 64-year-old patient with a history of hypertension and nonischemic cardiomyopathy presents for transthoracic echocardiography to evaluate left ventricular function and to quantify myocardial mechanics. The sonographer performs a standard comprehensive transthoracic echocardiogram including 2D imaging, Doppler, and color flow assessment. Following acquisition of standard views, the provider obtains high-quality digital cine loops in apical two-, three- and four-chamber views for speckle-tracking analysis. The interpreting cardiologist applies speckle-tracking software to calculate global longitudinal strain and regional strain values to supplement ejection fraction measurement, aiding assessment of subclinical myocardial dysfunction, cardiotoxicity monitoring, or risk stratification. Final documentation includes the standard echocardiographic findings, the provider-performed speckle-tracking results, and a statement that strain analysis was performed in addition to the standard echocardiographic interpretation. Typical site of service is the hospital outpatient department or an ambulatory echocardiography laboratory. Service type: diagnostic echocardiography with advanced myocardial mechanics analysis (93356).
