Tests not ordered by the physician or other qualified non-physician provider who is treating the patient are not reasonable and necessary (42 CFR 411.15(k) (1).42 CFR, Section 410.32 (b)Diagnostic x-ray and other diagnostic tests. (1) Basic rule  all diagnostic x-ray and other diagnostic tests covered under section 1861(s)(3) of the Act and payable under the physician fee schedule must be furnished under the appropriate level of supervision by a physician as defined in section 1861 of the Act. Services furnished without the required level of supervision are not reasonable and necessary.

Documentation must support the criteria as described in the Coverage Indications, Limitations, and/or Medical Necessity section of this LCD. There should be a permanent record of the studies performed and the interpretation. The documentation should include a description of the studies performed and any contrast media and/or radiopharmaceuticals used. Any known significant patient reaction or complications should be recorded. Comparison with prior relevant studies needs to be addressed in the documentation along with both normal and abnormal findings. Variations from normal should be documented along with measurements. The report should address or answer any specific clinical questions. If there are factors that prevent answering the clinical questions, this should be explained in the documentation. Retention of the ultrasound examination images and final interpretation should be consistent both with clinical need and with relevant legal and local health care facility requirements.If the provider of the study is other than the ordering/referring physician/nonphysician practitioner, that provider must maintain a copy of the test results and interpretation, along with copies of the ordering/referring physician/nonphysician practitioners order for the studies. This order is required to provide adequate diagnostic information to the performing provider. The physician/nonphysician practitioner must state the clinical indication/medical necessity for the study in his/her order for the test. The provider is responsible for ensuring the medical necessity of procedures and maintaining the medical record, which must be available to Medicare upon request. Results of all testing must be shared with the referring physician. Non-invasive vascular studies are medically reasonable and medically necessary only if the outcomes will be utilized in the clinical management of the patient.Utilization GuidelinesEach patients condition and response to treatment must medically warrant the number of services reported for payment. Medicare requires the medical necessity for each study reported to be clearly documented in the patients medical record.Frequency of follow-up studies will be carefully monitored for medical necessity and it is the responsibility of the physician/provider to maintain documentation of medical necessity in the patients medical record.Generally, it is expected that noninvasive vascular studies would not be performed more than once in a year, excluding inpatient hospital (21) and emergency room (23) places of services.Only one preoperative scan is considered reasonable and necessary for bypass surgery. If a more current preoperative scan is indicated for a patient with multiple comorbidities having difficulty being stabilized for surgery or a change in condition, the medical record would need to support the medical necessity of the second scan.In the immediate post-operative period, patients may be studied if re-established pulses are lost, become equivocal, or if the patient develops related signs and/or symptoms of ischemia with impending repeat intervention.The frequency of medically necessary follow-up noninvasive vascular studies post-angioplasty is dictated by the vascular distribution treated.Pre-surgical conduit mapping of the radial artery(ies) should only be accompanied by vein-mapping studies when the arterial studies demonstrate a non-acceptable conduit, or an insufficient conduit is available for multiple bypass procedures.Duplex scanning and physiologic studies may be reimbursed during the same encounter if the physiologic studies are abnormal and/or to evaluate vascular trauma, thromboembolic events or aneurysmal disease. The documentation must support the medical necessity.Assessment of the Ankle brachial indices (ABI) only is considered part of the physical examination and is not covered according to Title XVIII of the Social Security Act section 1862 (a) (7) which excludes routine physical examinations and services from Medicare coverage.Preventive and/or screening services unless covered in Statute are not covered by Medicare.
