Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- 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.
Key Coverage Criteria
- 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.
- CT thorax is covered for diagnosis and/or staging of neoplastic and hematologic processes arising in or involving the thorax.
- CT thorax is covered to evaluate pulmonary, mediastinal, pleural, and chest wall infections and their complications.
- CT thorax is covered to detect and characterize mediastinal neoplasms and other mediastinal processes.
