This article provides billing/coding guidelines that complement Local Coverage Determination L34417 for CT of the head; consult LCD L34417 for specific coverage, coding, and documentation requirements.
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.
RAST type tests are covered when medically necessary and supported by the related Local Coverage Determination (LCD) and current medical literature or standards of practice.
CPT code 86003 (RAST type test) is covered when billed for diagnostic testing, subject to the stated annual frequency limit.
