SUBJECT: NONINVASIVE
VASCULAR STUDIES
POLICY NUMBER:
DESCRIPTION:
The accuracy of diagnostic ultrasound and echocardiography
procedures depends on the knowledge, skill, and experience
of the technologist and interpreter. Consequently, the providers
of interpretations must be capable of demonstrating documented
training and experience and maintain documentation for post-payment
audit. (See Documentation Requirements section of
this policy for certificate/accreditation requirements.)
Vascular studies include patient care required to perform
the studies, supervision of the studies and interpretation
of study results with copies for patient records of hard copy
output or imaging when provided. The use of a simple hand-held
or other Doppler device that does not produce hard copy output,
or that does not permit analysis of bidirectional vascular
flow, is considered part of the physical examination of the
vascular system and is not separately reimbursable.1
Doppler procedures performed with zero-crossers (i.e., analog
[strip chart recorder] analysis) are also included in this
office visit as well.
The accuracy of noninvasive vascular diagnostic studies depends
on the knowledge, skill, and experience of the technologist
and interpreter. Consequently, the providers of interpretations
must be capable of demonstrating documented training and experience
and maintain documentation for post-payment audit. Furthermore,
effective January 1, 1997, all noninvasive vascular diagnostic
studies must be either (1) performed by, or under the direct
supervision of, persons that have demonstrated minimum entry
level competency by being credentialed in vascular technology,
or (2) performed in facilities with laboratories accredited
in vascular technology. Examples of appropriate personnel
certification include the Registered Vascular Technologist
(RVT) credential and the Registered Cardiovascular Technologist
(RCVT) credential in Vascular Technology, and appropriate
laboratory accreditation includes the Intersocietal Commission
for the Accreditation of Vascular Laboratories (ICAVL) or
the Ultrasound Practice Accreditation Commission of the American
Institute of Ultrasound in Medicine. Direct supervision requires
the credentialed individuals physical presence in the facility
during the examination.
Thermography, mechanical oscillometry, inductance plethysmography,
capacitance plethysmography, and photoelectric plethysmography
are not covered services. Light reflection rheography is not
a covered service based on lack of documentation of medical
necessity in the current literature.
It is the responsibility of the provider to ensure the medical
necessity of procedures and to maintain a record for post-payment
audit. Noninvasive vascular studies are medically necessary
only if the outcome will potentially impact the clinical course
of the patient. For example, if a patient is (or is not) going
to proceed on to other diagnostic and/or therapeutic procedures
regardless of the outcome of noninvasive studies, noninvasive
vascular procedures are not medically necessary. That is,
if it is obvious from the findings of the history and physical
examination that the patient is going to proceed to angiography,
then noninvasive vascular studies are not medically necessary.
A duplex scan includes a real-time scan (see CPT-4; Diagnostic
Ultrasound). Consequently billing for both a duplex scan and
echography of the same body part represents unbundling and
is not allowed.
As published in the Federal Register on November 22, 1996,
diagnostic tests, to be covered, must be ordered by the practitioner
that treats the patient. The treating physician is the practitioner
responsible for the treatment of the patient and who orders
the test to use the results in the management of the beneficiary's
specific medical problem(s). Consulting physicians may also
order tests.

INDICATIONS AND LIMITATIONS:
I. CEREBROVASCULAR EXAMINATION
(CPT Codes 93875 through 93888)
Indications For Cerebrovascular Evaluations:
1. Cervical bruits.
2. Amaurosis fugax.
3. Focal cerebral or ocular transient ischemic attacks (i.e.,
localizing symptoms, weakness of one side of the face, slurred
speech, weakness of a limb). Visual transient ischemic
attacks are defined as retinal or hemispheric visual
field deficits and not temporary blurred vision.
4. Drop attacks or syncope are rare indications primarily
seen with vertebrobasilar or bilateral carotid artery disease.
Incoordination or limb dysfunction should be grouped with
unilateral weakness of the face or extremities.
Examples Of Signs And Symptoms That Do Not Demonstrate
Medical Necessity
1. Dizziness is not a typical indication unless associated
with other localizing signs or symptoms. However, episodic
dizziness with symptom characteristics typical of transient
ischemic attacks may indicate medical necessity, especially
when other more common sources (e.g., postural hypotension
or transiently decreased cardiac output as demonstrated by
cardiac events monitoring) have been previously excluded.
2. Headaches are not an indication for extracranial studies.
TRANSCRANIAL DOPPLER (TCD) (93886 or 93888)
The accuracy of TCD examinations depends on the knowledge,
skill, and experience of the technologist and interpreter.
Consequently, the providers of TCD studies must be capable
of demonstrating documented training and experience and maintain
documentation for post-payment audit. An example of acceptable
training and experience would be a physician and/or registered
vascular technologist with documentation of attendance at
a formal TCD training program that includes hands on experience
and results in a certificate of proficiency, and
with a minimum experience of 100 patient TCD examinations.
TCD is an allowed procedure and is of established value in:
1. Detection and evaluation of the hemodynamic effects of
severe stenosis or occlusion of the extracranial (greater
than or equal to 60% diameter reduction) and major basal intracranial
arteries (greater than or equal to 50% diameter reduction).
2. Detection and serial evaluation of cerebral vasospasm complicating
subarachnoid hemorrhage.
3. Evaluation of invasive therapeutic interventions for cerebral
arteriovenous malformations.
4. Evaluation of intracranial hemodynamic abnormalities in
patients with suspected brain death.
5. Intraoperative and perioperative monitoring of intracranial
flow velocity and hemodynamic patterns during carotid endarterectomy.
This is primarily a Medicare Part A procedure but the professional
component could be reimbursed given it is provided during
the operative procedure by a physician that is not a member
of the operating team.
6. Evaluation of cerebral embolization.
Examples of non-acceptable indications include:
1. Evaluation of brain tumors.
2. Assessment of familial and degenerative diseases of the
cerebrum, brainstem, cerebellum, basal ganglia and motor neurons.
3. Evaluation of infectious and inflammatory conditions.
4. Psychiatric disorders.
5. Epilepsy.
II. PERIPHERAL ARTERIAL EXAMINATIONS
(CPT Codes 93920 - 93931)
Noninvasive peripheral arterial examinations, performed to
establish the level and/or degree of arterial occlusive disease,
are medically necessary if (1) significant signs and/or symptoms
of possible limb ischemia are present and
(2) the patient is a candidate for invasive therapeutic procedures.
A routine history and physical examination, which includes
Ankle/Brachial Indices (ABIs), can readily document the presence
or absence of ischemic disease in a majority of cases. It
is not medically necessary to proceed beyond the physical
examination for minor signs and symptoms such as hair loss,
absence of a single pulse, relative coolness of a foot, shiny
thin skin, or lack of toe nail growth unless related signs
and/or symptoms are present which are severe enough to require
possible invasive intervention.
An ABI (1) is not a reimbursable procedure in itself, and
(2) should be abnormal (i.e., < 0.9 at rest) and
must be accompanied by another appropriate indication before
proceeding to more sophisticated or complete studies, except
in patients with severe diabetes resulting in medial calcification
as demonstrated by artifactually elevated ankle blood pressures.
Peripheral Arterial Examinations
A. Indications For Peripheral Arterial Evaluations
1. Claudication of less than one block or of such severity
that it interferes significantly with the patient's occupation
or lifestyle.
2. Rest pain (typically including the forefoot), usually
associated with absent pulses, which becomes increasingly
severe with elevation and diminishes with placement of the
leg in a dependent position.
3. Tissue loss defined as gangrene or pregangreneous changes
of the extremity, or ischemic ulceration of the extremity
occurring in the absence of pulses.
4. Aneurysmal disease.
5. Evidence of thromboembolic events.
6. Blunt or penetrating trauma (including complications of
diagnostic and/or therapeutic procedures).
7. For evaluation of dialysis access, see policy regarding
CPT code 93990.
B. Examples Of Signs And Symptoms That Do Not Indicate Medical
Necessity
1. Continuous burning of the feet is considered to be a neurologic
symptom.
2. "Leg pain, nonspecific" and "Pain in limb"
as single diagnoses are too general to warrant further investigation
unless they can be related to other signs and symptoms.
3. Edema rarely occurs with arterial occlusive disease unless
it is in the immediate postoperative period, in association
with another inflammatory process or in association with rest
pain.
4. Absence of relatively minor pulses (i.e., dorsalis pedis
or posterior tibial) in the absence of symptoms. The absence
of pulses is not an indication to proceed beyond the physical
examination unless it is related to other signs and/or symptoms.
III. PERIPHERAL VENOUS EXAMINATIONS
(CPT Codes 93965-93971)
Indications for venous examinations are separated into two
major categories: deep vein thrombosis and chronic venous
insufficiency. Studies are medically necessary only if the
patient is a candidate for anticoagulation, thrombolysis or
invasive therapeutic procedures.
Since the signs and symptoms of arterial occlusive disease
and venous disease are so divergent, the performance of simultaneous
arterial and venous studies during the same encounter should
be rare. Consequently, a document clearly supporting the medical
necessity of both procedures performed during the same encounter
must be available for post-payment audit.
A. DEEP VEIN THROMBOSIS (DVT):
DVT is the most common vascular disorder that develops in
hospitalized patients and can develop after trauma or prolonged
immobility (sitting or bedrest). Unfortunately, the signs
and/or symptoms of DVT are relatively non-specific and, due
to the risk associated with pulmonary embolism (PE), objective
testing is allowed in patients that are candidates for anticoagulation
or invasive therapeutic procedures for the following indications:
1. Clinical signs and/or symptoms of DVT including edema,
tenderness, inflammation, and/or erythema.
2. Clinical signs and/or symptoms of PE including hemoptysis,
chest pain, and/or dyspnea.
3. Unexplained lower extremity edema status-post major surgical
procedures.
Bilateral limb edema in the presence of signs and/or symptoms
of congestive heart failure, exogenous obesity and/or arthritis
should rarely be an indication.
B. CHRONIC VENOUS INSUFFICIENCY:
Chronic venous insufficiency may be divided into three categories:
primary varicose veins, secondary varicose veins and post-thrombotic
(post-phlebitic) syndrome. It is not medically necessary to
study primary varicose veins. Objective tests of venous function
may be indicated in patients with ulceration
suspected to be secondary to venous insufficiency in order
to confirm this diagnosis by documenting venous valvular incompetence
prior to treatment.
Performance of both duplex scanning (93970 or 93971) and
physiological tests (93965) of extremity veins during the
same encounter is not medically necessary.
IV. HEMODIALYSIS ACCESS EXAMINATION
(CPT Code 93990)
Limited coverage has been established for duplex scanning
of hemodialysis access sites in patients with end stage renal
disease (ESRD). These procedures are medically necessary only
in the presence of signs or symptoms of impending failure
of the access site and when the results may impact the clinical
course of the patient. Evaluation of failed access sites are
not medically necessary. Furthermore, when services
are provided by the ESRD physician of record, services are
considered renal related and are, therefore, part of the physicians
monthly capitated fee and are not separately reportable. Services
performed by a Medicare approved ESRD facility are covered
services under the composite rate of the facility and therefore
not separately reimbursable.
Appropriate indications for Duplex scan of hemodialysis access
sites include:
ICD-9-CM code 996.73: Complication (Complication NOS, occlusion
NOS, embolism, fibrosis, hemorrhage, pain, stenosis, thrombosis)
due to renal dialysis device, implant, and graft; as demonstrated
by clear documentation in the dialysis record of signs of
chronic (i.e., 3 successive dialysis sessions) of abnormal
function including:
1) elevated venous pressure greater than 200 mmHg on a 300
cc/min pump, or
2) elevated recirculation time of 15% or greater at a flow
rate of 250 to 300 cc/min.
Routine evaluation on a daily or weekly basis without evidence
of the above is considered screening and is not a covered
service.
V. ULTRASOUND GUIDED REPAIR OF PSEUDOANEURYSM
(CPT Code 76936)
Diagnosis of pseudoaneurysm is primarily based on history
and physical examination. Consequently, CPT code 76936 includes
CPT codes 93926 through 93931 and these procedures are not
separately reimbursable. The medical necessity of ultrasound
guided repair of arteriovenous fistulae is not supported by
a review of the current literature and is, therefore, not
reimbursable.
Acceptable indications include a pulsatile mass indicating
a pseudoaneurysm and the patient must be at least three (3)
days status-post invasive vascular procedure. When performed
in conjunction with the invasive procedure, 76936 is considered
part of the invasive procedure and is not separately reportable.

CODING GUIDELINES:
Cerebrovascular Examination
A. Acceptable Procedures for Reimbursement
(CPT Codes 93875 - 93888)
1. Duplex scan (93880 or 93882).
2. Doppler ultrasound with spectrum analysis (93875).
3. Oculopneumoplethysmogaphy (OPPG) (93875).
4. Periorbital Doppler (93875) when OPPG is contraindicated.
5. Transcranial Doppler (TCD) (see below) (93886 or 93888).
Multiple cerebrovascular procedures can be allowed during
the same encounter given the provider can demonstrate medical
necessity on post-payment audit. That is, physiologic studies
and a duplex scan are allowed on the same date of service
given the provider is able to document medical necessity (e.g.,
greater than or equal to 50% stenosis on duplex scan or significant
symptoms as demonstrated by the indications for the study)
on post-payment audit.
B. Methods Not Acceptable For Reimbursement:
(CPT Codes 93875-93888)
1. Pulse delay oculoplethysmography.
2. Carotid phonoangiography and other forms of bruit analysis
are covered services but are included in the reimbursement
for the office visit.
3. Periorbital photoplethysmography.
C. Recommendations For Follow-up Studies:
(CPT Codes 93875-93888)
1. Stenosis of 20-50% (diameter reduction), an annual study.
2. Stenosis of 50-79%, every six months.
3. Stenosis of 80-99%, surgery is usually recommended.
4. After carotid endarterectomy, repeat examinations are allowed
at six weeks, six months, and one year. During the first year,
follow-up studies should be unilateral unless signs and symptoms
provide indications for a bilateral procedure.
PERIPHERAL ARTERIAL EXAMINATIONS
(CPT Codes 93920-93931)
A. Acceptable Procedures For Reimbursement
1. Duplex scan (93925, 93926, 93930, or 93931).
2. Single level physiologic studies (e.g., Doppler waveform
analysis, volume plethysmography, transcutaneous oxygen tension
measurement) (93922).
3. Segmental physiologic studies or with provocative functional
maneuvers (93923).
4. Physiologic studies at rest and following treadmill stress
testing (93924).
A complete extremity physiologic study includes pressure
measurements and an additional physiologic technique (e.g.,
Doppler ultrasound study or plethysmography).
Transcutaneous oxygen tension measurements are acceptable
to evaluate healing potential in nonhealing or difficult to
heal wounds at a frequency of no greater than twice in any
60 day period.
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, given the provider can document medical
necessity.
B. Methods Not Acceptable For Reimbursement
(CPT Codes 93920-93931)
1. Mechanical Oscillometry.
2. Inductance Plethysmography.
3. Capacitance Plethysmography.
4. Photoelectric Plethysmography.
5. ABI (considered part of the physical examination).
C. Post-intervention Follow-up Studies:
(CPT Codes 93920-93931)
Duplex post-interventional follow-up studies are typically
limited in scope and unilateral in nature.
Consequently, the "complete" duplex scan codes (i.e.,
93925 or 93930) should seldom be used while the "unilateral
or limited study" codes (i.e., 93926 or 93931) should
typically be used.
1. 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.
2. With regard to autogenous lower extremity vein bypass
surgeries, a study can be performed at three month intervals
during the first year, at six month intervals during the second
year, and annually thereafter. Follow-up studies are not medically
necessary post-angioplasty in the absence of signs and/or
symptoms of ischemia. Synthetic grafts may be studied if the
patient develops signs and/or symptoms of occlusive disease.
In general, noninvasive studies of the arterial system are
to be utilized when invasive correction is contemplated, but
not to follow noninvasive medical treatment regimens. The
latter may be followed with physical findings and/or progression
or relief of signs and/or symptoms. Screening of the asymptomatic
patient is not covered by Medicare.
PERIPHERAL VENOUS EXAMINATIONS
(CPT Codes 93965-93971)
A. Acceptable Procedures for Reimbursement:
1. Duplex scan (93970 or 93971).
2. Doppler waveform analysis including responses to compressions
and other maneuvers (93965).
3. Impedance Plethysmography (93965).
4. Air Plethysmography (93965).
5. Strain Guage Plethysmography (93965).
B. Methods Not Acceptable For Reimbursement:
1. Mechanical Oscillometry.
2. Inductance Plethysmography.
3. Capacitance Plethysmography.
4. Photoelectric Plethysmography.
Performance of both duplex scanning (93970 or 93971) and
physiological tests (93965) of extremity veins during the
same encounter is not medically necessary.
C. Follow-up Studies
Frequency of follow-up studies will be carefully monitored
for medical necessity and it is the responsibility of the
provider to maintain documentation of medical necessity for
post-payment audit.
