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.
Doppler interrogation must state the modes used and provide both qualitative and quantitative information.

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.
Visual field examinations are covered when reasonable and necessary as defined by Local Coverage Determination (LCD) L33766.
Erythrocyte sedimentation rate (ESR) testing is covered only when reasonable and necessary as defined by Local Coverage Determination L34021.
ESR performed for rheumatoid arthritis patients to assess the need for medication adjustments should be billed with a diagnosis code that reflects the specific antirheumatic medication the patient is receiving.
