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.

MRA is covered to evaluate blood flow in the internal carotid vessels of the head and neck.
MRA of peripheral arteries of the lower extremities is covered to determine the presence and extent of peripheral vascular disease and may substitute for conventional angiography (CA).
MRA is covered for pre-operative evaluation of patients undergoing elective abdominal aortic aneurysm (AAA) repair when it is comparable to CA for determining extent of AAA and evaluating aortoiliac occlusive disease and renal artery pathology necessary for surgical planning.
MRA of the renal arteries and aortoiliac arteries (in the absence of AAA or aortic dissection) is covered when MRA is expected to avoid CA, physician history/physical and standard assessments are insufficient, and obtaining MRA has a high probability of positively affecting patient management.
MRA of the chest is covered for diagnosis of suspected pulmonary embolism when the patient has a contraindication to receiving intravascular iodinated contrast material.
MRA of the chest is covered for pre-operative and post-operative evaluation of thoracic aortic dissection and thoracic aortic aneurysm and may be used as an alternative to other non-invasive imaging when clinically appropriate.
