Policy references and complements Local Coverage Determination L33417 for Allergy Skin Testing; full LCD and policy text required to determine specific documentation and billing rules.
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 patient's medical record must contain documentation that fully supports medical necessity, including relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.

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.
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.
Home-based ECG services (including additional payment above the base ECG amount for transportation) are covered when there is a documented medical need to perform the ECG in the patient's home, typically for homebound or bed-confined patients.
A second professional component (PC) interpretation may be paid when a second physician’s substantially greater expertise is necessary and reasonable to clarify a questionable or confusing ECG finding and contributes substantially to diagnosis or treatment.
