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.

Non-invasive vascular studies (duplex scan, physiologic studies, plethysmography, transcranial Doppler) are covered when ordered by the treating or consulting practitioner and medically necessary to evaluate, diagnose, or manage vascular disease.
Initial autogenous access vessel mapping should be billed with HCPCS codes 93985 or 93986 and is covered when medically necessary for surgical planning.
Subsequent autogenous access mapping may be billed with CPT codes 93970 or 93971 when clinically indicated.
Pre-surgical radial artery conduit mapping may be performed and accompanied by vein-mapping when either study shows insufficient conduits for multiple bypass procedures.
Immediate post-operative studies of an access or bypass site are covered if pulses are lost, become equivocal, or the patient develops signs or symptoms of ischemia suggesting need for repeat intervention.
Electrodiagnostic testing (EMG and/or nerve conduction studies) is indicated for evaluation of suspected carpal tunnel syndrome.
