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.
All documentation must be maintained in the patient's medical record and made available to the contractor upon request.
Every page of the medical record must be legible and include appropriate patient identification (e.g., complete name and dates of service).
The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.

Ultrasound of soft tissues of the head and neck is covered when it is reasonable and necessary as defined by Local Coverage Determination L34027.
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.
An ECG is covered when the result is relevant to the management, diagnosis, or treatment of the patient.
A separate ECG on the same day as a cardiac stress test is payable only when it provides additional clinically necessary information beyond the stress test (e.g., to rule out acute myocardial infarction prior to performing the stress test).
Rhythm ECGs are covered when used to evaluate signs or symptoms suggesting a cardiac rhythm disorder.
