This billing/coding guideline complements LCD L33459 (Computerized Axial Tomography (CT), Thorax); follow the LCD for clinical coverage and any required documentation or prior authorization rules.
The medical record must contain documentation fully supporting medical necessity, including relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.
Each echocardiography service requires a formal written report with interpretation retained in the record and copies of image documentation (paper or electronic) available for review.
A complete study must include M-mode and/or 2D measurements of LV end-diastolic diameter, LV end-systolic diameter, LV wall thickness, left atrial diameter, aortic valve excursion, and a qualitative description of LV function, or valid substitutes such as LV volumes, ejection fraction, and mass.

Transthoracic echocardiography (TTE) is covered when the patient's medical record documents medical necessity consistent with the LCD indications for TTE.
Contrast (contrast-enhanced) echocardiography is covered when conventional echocardiographic studies were inconclusive and contrast enhancement is needed to complete diagnostic evaluation.
Repeat echocardiographic studies are covered to monitor changes in cardiac structure or function when there is a change in clinical status or when disease progression is suspected.
TTE is indicated to assess cardiac effects of systemic hypertension, including detection of left ventricular hypertrophy to guide long-term antihypertensive therapy.
TTE is indicated to evaluate ventricular function, cardiomyopathies, and heart failure when history, physical exam, or routine labs suggest or cannot exclude cardiac disease.
TTE is indicated in acute myocardial infarction or suspected acute ischemia to evaluate regional wall motion, right ventricular ischemia/infarction, and complications (e.g., mural thrombus, papillary muscle dysfunction, septal defects, aneurysm).
