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.
When a limited or follow-up echocardiogram is performed, document the targeted cardiac problem/region and bill using the appropriate CPT code (93308 or 93321).
If the study is a screening exam, document and bill with the appropriate screening ICD-10 code; document any abnormal findings and use the resulting diagnosis for subsequent billing when applicable.
Document use of ultrasound contrast enhancement and its supplies separately when billed, and do not submit separate claims for diagnostic injection services integral to the contrast procedure.

Follow-up or limited transthoracic echocardiography performed to evaluate a single specified cardiac problem or region must be billed with CPT 93308.
Limited Doppler/follow-up echocardiographic studies (for targeted velocity or gradient assessment) should be billed with CPT 93321 (e.g., tricuspid regurgitant velocity to estimate pulmonary artery systolic pressure or sequential transmitral velocity in mitral stenosis).
Neurophysiology Evoked Potentials (NEPs) — including Somatosensory Evoked Potentials (SEPs), Brainstem Auditory Evoked Potentials (BAEPs/BAERs), and Visual Evoked Potentials (VEPs/VERs) — are covered when determined to be reasonable and necessary in accordance with LCD L34975.
CT or MRI scans of the head or neck are covered when the medical record documents the scan is reasonable and necessary for diagnostic evaluation.
Coverage requires documentation supporting clinical indication such as history and physical exam findings, laboratory results, and signs or symptoms that justify the diagnostic test.
