Claims must meet the reasonable and necessary documentation requirements specified in LCD L35035; include clinical records demonstrating medical necessity per the LCD.
Follow the NCCI Coding Policy Manual (Chapters V and IX) for proper coding; retain documentation supporting compliance with NCCI edits.
When billing services that the LCD does not cover, use the appropriate Medicare modifier and document the basis for billing a non-covered service.
The medical record must contain relevant medical history, physical examination, and results of pertinent diagnostic tests that fully support the medical necessity of each non-invasive vascular study.

Coverage for thoracic aortography and carotid, vertebral, and subclavian angiography is determined by Local Coverage Determination L35035; services are covered when reasonable and necessary per that LCD.
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.
