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.
Diagnostic tests must be ordered by the treating practitioner (or consulting physician) who will use the test results in managing the patient's specific medical problem; the ordering practitioner's name and NPI must be reported on the claim when required.
Providers of interpretations and technical personnel must maintain documentation of training, licensure, certification, and proficiency for post-payment audit; IDTF supervising physicians must document proficiency in each diagnostic procedure performed.
For diagnostic tests, report the test result if known; if not known, report the symptoms prompting the test on the claim.

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.
Nerve conduction studies (NCS) without needle EMG (NEMG) are allowed for individuals being evaluated for carpal tunnel syndrome or tarsal tunnel syndrome when one of the following ICD-10-CM codes is reported: G56.01, G56.02, G56.03, G56.11, G56.12, G56.13, G56.21, G56.22, G56.23, G57.51, G57.52, or G57.53.
