Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- The patient's medical record must contain documentation that fully supports the medical necessity for the visual fields testing in accordance with the applicable LCD.
- Documentation should include relevant medical history, a physical examination, and results of pertinent diagnostic tests or procedures supporting the need for visual fields testing.
- The diagnosis code(s) reported on the claim must best describe the patient's condition for which the visual fields testing was performed.
- Refer to NCCI and OPPS requirements prior to billing Medicare to ensure coding compliance and to determine any bundling or packaging edits.
Key Coverage Criteria
- No specific clinical indications are listed in this billing/coding guidance; coverage determinations for MRI of the head and neck follow Local Coverage Determination L34425.
- Ultrasound of soft tissues of the head and neck is covered when it is reasonable and necessary as defined by Local Coverage Determination L34027.
- 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.
