Thuong Vo, M.D. and Nga Thieu Du, Respondents.

DATE: August 15, 1989
Docket No. C-45

DECISION OF ADMINISTRATIVE LAW JUDGE

Respondents requested a hearing to contest the proposed imposition against them, jointly and severally, of
civil monetary penalties and assessments. Based on the law, regulations, and evidence adduced at the
hearing in this case, I conclude that Respondents Thuong Vo, M.D. a/k/a Thomas Vo, M.D. (Respondent
Vo) and Nga Thieu Du (Respondent Du) presented, or caused to be presented, claims for 64 items or
services which they knew, had reason to know, or should have known were not provided as claimed. I
impose civil monetary penalties of $128,000.00 and assessments of $3,890.00 against them, jointly and
severally, for a total of $131,890.00.


BACKGROUND

On June 16, 1988, the Deputy Inspector General, Civil Administrative Division, notified Respondents that
pursuant to authority delegated to her by the Secretary of Health and Human Services (the Secretary) and
the Inspector General (the I.G.), she was proposing to impose civil monetary penalties and assessments
against them. Specifically, she proposed that Respondents jointly and severally be penalized $128,000.00,
and assessed $3,890.00, for a total of $131,890.00. She cited as legal authority for the proposal section
1128A of the Social Security Act, 42 U.S.C. 1320a-7a, as implemented by 42 C.F.R. 1003.100 et seq.

The Deputy Inspector General also proposed that Respondents be excluded from participating in the Title
XVIII (Medicare), Title XIX (Medicaid), Title V (Maternal and Child Health Block Grant), and Title XX
(Social Services Block Grant) programs for a period of ten years. She cited as legal authority for the
proposed exclusions section 1128A(a) of the Social Security Act, 42 U.S.C. 1320a-7a(a).

The proposed penalties, assessments, and exclusions were based on the Deputy Inspector General's
allegations that Respondents presented, or caused to be presented, to the California Medicaid program
(Medi-Cal), claims, containing 64 items or services, requesting $1,945.00 in reimbursement for office
visits and laboratory tests which were not provided as claimed. She asserted that Respondents knowingly
improperly claimed reimbursement for services allegedly rendered on behalf of nonexistent individuals.
Each of the allegedly false items or services was itemized as a separate count in an attachment to the
Deputy Inspector General's notice to Respondents.

The Deputy Inspector General advised Respondents that she was proposing that the maximum penalties
and assessments permitted by law be imposed against them. She told Respondents that her proposal was
based on factors specified by regulations. These included:

1. the presence of aggravating circumstances in Respondents' case, including Respondents'
participation, from August 1982 until February 1984, in an elaborate scheme to defraud government health
care programs;

2. Respondents' substantial culpability, as evidenced by Respondents' knowledge that the
services claimed had not been provided, and Respondents' conviction by a California court of crimes
related to the claims at issue;

3. Respondents' not previously having been convicted of similar offenses;

4. the absence of information to suggest that the imposition of the proposed penalties and
assessments would jeopardize Respondents' ability to continue as health care providers;

5. the presence of other aggravating factors, including Respondents' participation in a highly
organized conspiracy to defraud Medi-Cal.

Respondent Vo timely requested a hearing. The request filed on his behalf did not request a hearing on
behalf of Respondent Du. The case was assigned to me for a hearing and decision. I held a prehearing
conference on November 15, 1988, at which counsel agreed that Respondent Vo's hearing request would
be deemed to be a timely hearing request on behalf of Respondent Du.

The I.G. subsequently filed a motion for summary disposition against both Respondents as to three items or
services itemized in the first three counts of the attachment to the Deputy Inspector General's notice.
Respondents did not oppose this motion, and, on February 21, 1989, I issued a ruling which granted the
I.G.'s motion.

My ruling was based on the I.G.'s undisputed assertion that Respondents pleaded guilty to crimes involving
fraudulent presentation of Medi-Cal claims as enumerated in counts 1-3. I concluded that Respondents'
convictions constituted "prior determinations" with respect to the items or services enumerated in counts 1-
3. Therefore, pursuant to 42 C.F.R. 1002.114(c), the doctrine of collateral estoppel applied to these items
or services. I made no finding in my ruling as to the appropriateness of penalties or assessments with
respect to these false claims, and I stated that I would not preclude Respondents from offering evidence on
the issue of the appropriateness of penalties or assessments.

I conducted a hearing in this case in Santa Ana, California on March 6, 1989. At the hearing, the I.G.
withdrew the proposal to exclude Respondents from participating in health care programs under Titles V,
XVIII, XIX, and XX.

At the completion of the hearing, I issued a schedule for the parties to file posthearing briefs and reply
briefs. The I.G. timely filed a posthearing brief on April 26, 1989. Respondents did not file a posthearing
brief. On May 19, 1989, I invited the parties to brief the possible impact on this case of a recent United
States Supreme Court decision, United States v. Halper, No. 87-1383 (May 15, 1989). The I.G. timely
filed a brief addressing the impact of the Halper decision. Respondents did not file a brief on Halper. On
June 27, 1989, I issued an Order closing the record in this case.

U.S.C. 1320a-7a; and

2. penalties and assessments should be imposed against either Respondent and, if so, in what
amount.

86. This proceeding is governed by the Civil Monetary Penalties Law, 42 U.S.C. 1320a-7a, (the Act) and
by enabling regulations contained in 42 C.F.R. Part 1003.

87. The Act authorizes the Secretary to impose a civil monetary penalty and an assessment against any
person who presents or causes to be presented, to an officer, employee or agent of any State, a claim for
items or services under Title XIX (Medicaid) which that person knew or should have known was not
provided as claimed. 42 U.S.C. 1320a-7a(a),(i)(2).

88. Prior to December 1987, the Act provided for imposition of a penalty, assessment, and exclusion
against a person who filed a claim for an item or service where that person "knows or has reason to know"
that the item or service was not filed as claimed. 42 U.S.C. 1320a-7a(a). Effective December 22, 1987,
the phrase "should know" was substituted for the phrase "has reason to know." Pub. L. 100-203, section
4118(e) (1987). Section 4118(e)(3) of this law provided that the language substitution was intended to
apply retroactively.


89. The Act provides for the imposition of a penalty of up to $2,000.00 for each item or service falsely
claimed and assessments of up to twice the amount so claimed. 42 U.S.C. 1320a-7a(a).

90. The Act and regulations direct the Secretary or his or her delegate, in determining the amount or scope
of any penalty or assessment imposed, to take into account both aggravating and mitigating factors. 42
U.S.C. 1320a-7a(d); 42 C.F.R. 1003.106.

91. Factors which may be considered as aggravating or mitigating include: the nature of the claims and
the circumstances under which they were presented; the degree of culpability, history of prior offenses, and
financial condition of the person presenting the claims; and such other matters as justice may require. 42
U.S.C. 1320a-7a(d); 42 C.F.R. 1003.106.

92. If there are substantial or several aggravating circumstances, the aggregate amount of the penalty and
assessment should be set at an amount sufficiently close to, or at, the maximum permitted by law, so as to
reflect that fact. 42 C.F.R. 1003.106(c)(2).

93. In proceedings brought pursuant to the Act, the I.G. has the burden of proving, by a preponderance of
the evidence, that a respondent presented, or caused to be presented, claims for items or services which the
respondent knew or should have known were not provided as claimed. 42 C.F.R. 1003.114(a).

94. In proceedings brought pursuant to the Act, a respondent has the burden of proving the existence of
any mitigating factors. 42 C.F.R. 1003.114(d).

95. Respondents' guilty plea to Count 1 of the amended felony complaint filed against them constitutes a
final determination with respect to the items or services specified in Count 1 of the amended felony
complaint and listed as counts 1-3 of the attachment to the notice.

96. Respondents are, therefore, bound by that final determination in this proceeding.

97. Respondent Vo presented, or caused to be presented, to Medi-Cal, claims for the items or services
listed in counts 1-64 of the attachment to the notice, and he knew that they were not provided as claimed.

items or services listed as counts 1-64 in the attachment to the Deputy Inspector General's June 18, 1988

110. Respondent Du was a participant with Respondent Vo in this conspiracy to defraud Medi-Cal.
Findings 16, 60, 64, 66, 68, 80-83.

111. Respondents have not established any of the allegations made by them which could be construed as
mitigating factors.

112. Respondents have not established that they were entrapped into presenting the claims for items or
services listed as counts 1-64 in the attachment to the notice.

113. Respondents have not established that they were targets of a plan to single out Vietnamese providers
for prosecution.

114. Respondents have not established that their actions were motivated by sympathy for the relatives in
Vietnam of Vietnamese Medi-Cal patients.

115. Respondents have not established that the imposition against them of penalties of $128,000.00 and
assessments of a $3,890.00, for a total of $131,890.00, will jeopardize their ability to continue as health
care providers.

116. Penalties of $128,000.00 and assessments of $3,890.00 against Respondents, jointly and severally,
are appropriate in this case.


ANALYSIS

1. Respondents presented, or caused to be presented, claims for items or services which they
knew, had reason to know, or should have known were not provided as claimed.

Based on the evidence of record, I conclude that Respondent Vo presented, or caused to be presented,
claims for 64 items or services that he knew, had reason to know, or should have known were not provided
as claimed.

I conclude further, based on the principles of collateral estoppel contained in 42 C.F.R. 1003.114(c), that
Respondent Du presented, or caused to be presented, claims for three items or services that she knew were
not provided as claimed. I conclude that the I.G. did not prove that Respondent Du knew that the items or
services listed as counts 4-64 in the attachment to the notice were not provided as claimed. However, I
conclude that Respondent Du had reason to know or should have known that these items or services were
not provided as claimed.

a. Respondent Vo.

The first element of proof which the I.G. must establish in order to prove liability in a case brought
pursuant to the Act is that a respondent presented, or caused to be presented, the claims for the items or
services at issue. 42 U.S.C. 1320a-7a(a); 42 C.F.R. 1003.102. Respondent Vo caused the items or services
at issue to be presented. He prepared the medical records on which the claims for the items or services
were based, and he personally signed the claim forms on which the items or services were presented to
Medi-Cal. Findings 13-15; 29, 38, 49.

The next element of proof which the I.G. must establish is that the items or services were not provided as
claimed. 42 U.S.C. 1320a-7(a)(1); 42 C.F.R. 1003.102. In this case there can be no doubt that the 64
items or services at issue were not provided as claimed. This is so because the patients to whom these
alleged items or services were purportedly rendered did not exist.

The evidence establishes that, in early 1983, the Fraud Bureau received complaints that physicians,
including Respondent Vo, were writing prescriptions and making claims to Medi-Cal for services provided
to patients who did not exist. Findings 17-18. Agents of the Fraud Bureau created Medi-Cal cards for
nonexistent persons and engaged in three undercover operations with respect to Respondent Vo. Findings
20, 24. All of the 64 claims for items or services at issue in this case were purportedly rendered to the
nonexistent persons whose names and Medi-Cal identification numbers appeared on these cards. Findings
29-30, 33, 38-41, 44, 50-51, 53. As there were no patients to whom services could have been rendered,
there were no services. The "services" for which Respondent Vo presented claims described in counts 1-64
were never provided to anyone and, therefore, were not provided as claimed.

The final element of proof which the I.G. must establish in proving liability pursuant to the Act is that a
respondent bears requisite culpability for the claims at issue. The Act presently provides that this test is
satisfied where it is shown that a respondent either knows, or should know, that the items or services at
issue were not provided as claimed. 42 U.S.C. 1320a-7a(a)(1)(A).

Respondent Vo knew that the items or services at issue were not provided as claimed. He admitted
orchestrating a scheme to steal from Medi-Cal. Finding 73. He admitted paying drivers to bring Medi-Cal
cards without patients. Finding 74. He admitted knowingly presenting false claims for services that he
never rendered. Findings 75-76. Respondent Vo admitted that his intent was to cheat and defraud Medi-
Cal. Finding 77. He admitted stealing more than $25,000.00 from Medi-Cal. Finding 78. He admitted
that three of the items or services at issue in this case, listed in counts 1-3 of the attachment to the notice,
were falsely claimed in furtherance of his criminal scheme. Findings 71-72. The other items or services at
issue in this case arose from the same undercover operations and transactions that led to these admissions.
Findings 25-53. It is reasonable to infer that they are also part of Respondent Vo's scheme to defraud
Medi-Cal.

Respondent Vo personally created the medical records upon which his Medi-Cal claims were based.
Findings 13-14; see I.G. Ex. 6-2/333. Inasmuch as the claims at issue relate to patients who do not exist,
Respondent Vo had to fabricate the records upon which the claims were based. When Respondent Vo
fabricated these records, he had to have done so intending that false claims would be predicated upon them.
There would have been no other reason for him to create false patient records.

Respondent Vo denies that he knew that the items or services at issue were not provided as claimed or that
he ever intended to steal money from Medi-Cal. I.G. Ex. 6-1/312. He premises his denials on his assertion
that he signed claims "weeks, or 20 days or one month after I saw the patient," thereby implying that by the
time he signed the claims he no longer remembered the items or services that the claims represented. Id.

I conclude that this assertion is largely incredible. The record establishes that many of the claims at issue
were presented on the same day or within a few days of the "treatments" on which they were allegedly
based. I.G. Ex. 7-1-7-17. Several of the claims arising from the May 18, 1983 undercover operation were
presented within one week of that date. All except one of the claims arising from the August 30, 1983
undercover operation were presented on that same day. I conclude that Respondent Vo certainly
remembered fabricating treatment records for these claims when he signed the claims.

Assuming, for argument's sake, that Respondent Vo could not remember whether he had fabricated the
items or services presented in a given claim at the moment he signed the claim form, he nevertheless knew
that he was presenting claims for items or services that were not provided as claimed, including the items
or services at issue in this case. Respondent Vo deliberately falsified the records on which claims were
based in furtherance of his scheme to defraud Medi-Cal. When he fabricated treatment records, he knew
that, ultimately, false claims would be presented based on those false records. He thus knew that he was
presenting claims for items or services that were not provided as claimed, and he had specific knowledge
that false claims would be presented based on the fabricated records he created. I conclude that this level
of knowledge suffices to satisfy the "knows" standard of 42 U.S.C. 1320a-7a(a), even if days or weeks
after falsifying the treatment records Respondent Vo no longer remembered which record pertained to
which claim.

Respondent Vo had reason to know that the items or services at issue were not provided as claimed. The
"reason to know" standard contained in the Act prior to December 22, 1987 created a duty on the part of a
provider to prevent the submission of false or improper claims where: (1) the provider had sufficient
information to place him, as a reasonable medical provider, on notice that the claims presented were for
services not provided as claimed, or (2) there existed pre-existing duties which would require a provider to
verify the truth, accuracy, and completeness of claims. The Inspector General v. George A. Kern, M.D.,
Docket No. C-25, decided August 26, 1987, at pp. 5-7; see The Inspector General v. Frank P. Silver, M.D.,
Docket No. C-19, Decision and Order on Remand, decided July 2, 1987, at p. 24.

The "reason to know" standard is a less stringent standard for liability under the Act than the "knows"
standard. In this case, evidence concerning Respondent Vo's activities and knowledge satisfies both the
"reason to know" and the "knows" standards.

The evidence in this case satisfies both elements of the "reason to know" test as applied to Respondent Vo.
Because Respondent Vo was generating the fabricated patient records on which false claims were based, he
had sufficient information to place him on notice that the claims presented for the items or services at issue
were for services not provided as claimed. Furthermore, Respondent Vo was under a pre-existing duty to
verify the truth, accuracy, and completeness of the claims he signed, including the claims presented for the
items or services at issue. By his own admission, he ignored this duty. I.G. Ex. 6-2/312.

On each claim form that Respondent Vo signed, he certified that the information contained on the form
was true, accurate, and complete and that he agreed to be bound by, and comply with, the statements and
conditions on the back of the form. J. Ex. 3. The back of each claim form signed by Respondent Vo
contained a statement under the heading "IMPORTANT" which provided in relevant part that:

The services listed on this form have been personally provided to the patient by the provider or,
under his direction, by another person eligible under the Medi-Cal Program to provide such services, and
such person(s) are designated on this form. The services were, to the best of the provider's knowledge,
medically indicated and necessary to the health of the patient. The provider understands that payment of
this claim will be from Federal and/or State funds, and that any falsification, or concealment of a material
fact, may be prosecuted under Federal and/or State laws.

J. Ex. 3.

Respondent Vo had a duty to investigate whether the facts represented on any claim were true before
signing the form. Every form that he signed explicitly stated that obligation. Respondent Vo represented
that he had complied with this duty every time he signed a claim form. However, Respondent Vo asserted
that he signed these forms without recalling the patients whose services they recorded or the treatments
claimed for reimbursement. I.G. Ex. 6-2/312.

Respondent Vo should have known that the items or services listed in counts 1-64 of the attachment to the
notice were not provided as claimed. The "should know" test for liability encompasses a less stringent
standard than the "reason to know" test. See In the Matter of The Inspector General v. Frank P. Silver,
M.D., Docket No. C-19, Opinion of Deputy Under Secretary, decided April 27, 1987. "Should know"
subsumes reckless disregard for the consequences of a person's acts. The test also subsumes negligence in
preparing and submitting, or in supervising the preparing and submitting of, claims. Mayers v. U.S. Dept.
of Health and Human Services, 806 F.2d 995 (11th Cir. 1986), cert. denied, U.S. (1988).

If nothing else, Respondent Vo's conduct in signing claim forms constituted reckless disregard for the truth
of the contents of those forms. I have not accepted as credible Respondent Vo's testimony that he was
unaware of what he was signing. But assuming he was truthful on this point, his testimony establishes that
he was signing claim forms without any regard for what those forms contained. That amounts to reckless
conduct, which satisfies the "should know" standard.

b. Respondent Du.

Respondent Du admitted filing false claims with Medi-Cal, and the false claims she admitted filing include
the three items or services specified in counts 1-3 of the attachment to the notice. I conclude, based on
these admissions, and the terms of 42 C.F.R. 1003.114(c), that she presented or caused to be presented the
items or services enumerated at counts 1-3 and that she knew that they were not provided as claimed.

I conclude that Respondent Du presented, or caused to be presented, the claims containing the items or
services included in counts 4-64 of the attachment to the notice. She was employed in Respondent Vo's
office; her duties included double-checking claims for Medi-Cal reimbursement before they were signed
by Respondent Vo and presented. Finding 16. She, therefore, directly participated in the chain of events
which resulted in the presenting of these items or services.

The I.G. did not establish that Respondent Du knew that the items or services enumerated in counts 4-64
were not provided as claimed. Although there is considerable evidence in this case to establish that
Respondent Du was a co-conspirator in the scheme to defraud Medi-Cal, the record does not establish that
Respondent Du assisted Respondent Vo in fabricating patient treatment records. See Findings 54-68; 80-
85. Therefore, unlike Respondent Vo, there is no evidence which establishes that she had direct knowledge
that particular claims were based on falsified records.

However, Respondent Du had reason to know that the items or services listed in counts 4-64 of the
attachment to the notice were not provided as claimed. Respondent Du had sufficient information to place
her on notice that she had presented claims for items or services, including the items or services at issue in
this case, which were not provided as claimed. She abetted Respondent Vo's actions. She was the recruiter
and the paymaster of the drivers. Findings 56-68. She encouraged drivers to bring Medi-Cal cards to her,
without patients, for the obvious purpose of generating false Medi-Cal claims. Id. The claims for the items
or services at issue in this case are the end result of Respondent Du's actions. The evidence concerning
Respondent Du therefore satisfies the first element of the "reason to know" test described supra.

Respondent Du should have known that the items or services listed in counts 4-64 were not provided as
claimed. Even if she did not know whether any particular claim was false, she knew that many of them
had to be false. She was directly involved in preparing claims, including double-checking claims for
accuracy. She manifested a reckless disregard for the truthfulness of the claims she assisted in preparing.

2. A penalty of $128,000.00 and an assessment of $3,890.00 against Respondents, jointly and
severally, is appropriate in this case.

The remedial purpose of the Act is to protect government financed health programs from fraud and abuse
by providers. Mayers, supra, 806 F.2d at 997. The penalty and assessment provisions of the Act are
designed to implement this remedial purpose in two ways. One is to enable the government to recoup the
cost of bringing a respondent to justice and the financial loss to the government resulting from the false
claims presented by that respondent. The other is to deter other providers from engaging in the false claims
practices engaged in by a particular respondent. Id. at 999.

The Act and implementing regulations provide that a penalty of up to $2,000 and an assessment of not
more than twice the amount claimed may be imposed on a respondent for each item or service which is
established as not having been provided as claimed. 42 U.S.C. 1320a-7a(a); 42 C.F.R. 1003.103-104. In
this case, the maximum penalties which I may impose against each Respondent are $128,000.00, based on
the presentation for payment of 64 items or services which were not provided as claimed. The maximum
assessments which I may impose are $3,890.00, based on total claims for $1,945.00 for the items or
services at issue in this case.

Regulations prescribe that, in determining the amount of a penalty and assessment, I must consider as
guidelines factors which may either be mitigating or aggravating. 42 C.F.R. 1003.106. These include: (1)
the nature of the claim or request for payment and the circumstances under which it was presented, (2) the
degree of culpability of the person submitting the claim or request for payment, (3) the history of prior
offenses of the person submitting the claim or request for payment, (4) the financial condition of the person
presenting the claim or request for payment, and (5) such other matters as justice may require. 42 C.F.R.
1003.106(a).

The I.G. has the burden of proving the presence of aggravating factors. 42 C.F.R. 1003.114(a). A
respondent has the burden of proving the presence of mitigating factors. 42 C.F.R. 1003.114(c). The
regulations provide that, in cases where mitigating factors preponderate, the penalty and assessment should
be set sufficiently below the maximum permitted by law. 42 C.F.R. 1003.106(c)(1). The regulations also
provide that, in cases where aggravating factors preponderate, the penalty and assessment should be set
close to the maximum permitted by law. 42 C.F.R. 1003.106(c)(2).

The Act has been interpreted to permit the imposition of a penalty and assessment which exceeds the
amount actually reimbursed to a respondent for items or services not provided as claimed. Chapman v.
U.S. Dept. of Health & Human Services, 821 F.2d 523 (10th Cir. 1987); Mayers, supra, 806 F.2d at 999.
This reflects the legislative determination that activities in violation of the act "result in damages in excess
of the actual amount disbursed by the government to the fraudulent claimant." Mayers, supra, 806 F.2d at
999.

I have considered Respondents' conduct in light of the evidence and the Act's remedial purpose and
regulatory criteria, and I conclude that the maximum penalty and assessment permitted by the Act should
be imposed against each Respondent. The I.G. established many aggravating factors with respect to each
Respondent. Neither Respondent established any mitigating factors.

a. Respondent Vo.

Respondent Vo presented or caused to be presented the items or services at issue over a four month period,
a lengthy period of time. Finding 103. The 64 items or services which Respondent Vo presented or caused
to be presented for payment which were not provided as claimed constitute a substantial number of such
items or services. Finding 104. Respondent Vo claimed $1,945.00 as reimbursement for the items or
services at issue, and this is a substantial amount. Finding 106.

These circumstances are aggravating factors as defined by regulation. 42 C.F.R. 1003.106(b)(1). The
presence of these factors alone would, absent proof of mitigation, justify my imposing a substantial penalty
and assessment against Respondent Vo. However, there exist other aggravating circumstances in this case
which are far more serious than those just cited.

The evidence establishes that the items or services at issue were but a small part of a pattern of fraudulent
conduct perpetrated by Respondent Vo. Respondent Vo conspired to defraud Medi-Cal. In order to effect
his plan, he enlisted the services of many individuals, including those of Respondent Du. His scheme
consisted of a concerted and, for a time, successful plan to deceive Medi-Cal's intermediary into paying
Respondent Vo for falsified Medi-Cal services.

When considered in its entirety, the evidence in this case proves that Respondent Vo engaged, over a long
period of time, in a well-organized, sophisticated, and massive theft from a government-financed health
care program. Findings 73-79; 107-108. The scope and effect of this conspiracy can, in some respects, be
measured by that to which Respondent Vo admitted. He admitted to stealing in excess of $25,000.00 from
Medi-Cal and to being overpaid $85,598.00 by Medi-Cal. Findings 78-79. Moreover, there is evidence
beyond Respondent Vo's admissions which suggests an even greater scope to the conspiracy than that to
which he admitted. The drivers' notebooks, seized from Respondent Vo's office, record transactions
spanning a 17-month period. Finding 57. Individuals identified as drivers admit to supplying Respondents
with Medi-Cal cards during this period. Findings 59, 63, 67.

Respondent Vo, therefore, manifests a high degree of culpability, an aggravating factor described in 42
C.F.R. 1003.106(b)(2). Furthermore, the items or services which are the subject of this case are merely an
element in a pattern of unlawful conduct by this Respondent which comprises his conspiracy to defraud
Medi-Cal. A similar pattern of unlawful conduct was found to be an aggravating circumstance in the
Mayers case, and the court held that it amply justified the penalty and assessment imposed on the
respondents in that case. 806 F.2d at 999.

Respondent Vo established no mitigating factors. He offered no evidence to show that imposing against
him the penalties and assessments sought by the I.G. would jeopardize his ability to continue as a health
care provider. See 42 C.F.R. 1003.106(b)(4). He did not rebut the I.G.'s case concerning the nature of his
offense or the scope and pattern of his conduct.

Respondent Vo made several allegations concerning this case which, if proven, might arguably constitute
mitigating factors. Respondent Vo alleged that he was singled out as part of a campaign in California by
State government against Vietnamese providers, that he was entrapped into filing the claims for the items
or services at issue, and that he presented, or caused to be presented, the claims for the items or services at
issue because of his compassion for members of the Vietnamese community in California and relatives in
Vietnam of members of this community.

Respondent Vo offered no credible evidence to substantiate these allegations. His assertion that he was
singled out for investigation and prosecution by State authorities because of his ethnic origin is premised
exclusively on the fact that undercover investigations were conducted at the same time against several
Vietnamese providers. The logical explanation for this is that complaints had been made against
Vietnamese providers, including Respondent Vo. Finding 17. It would have been illogical for the Fraud
Bureau to target its investigation against parties other than the subjects of the complaints.

There is no evidence that Respondent Vo was entrapped when he obtained false Medi-Cal cards and
presented, or caused to be presented, claims for items or services that were not provided as claimed. To the
contrary, the evidence establishes that Respondent Vo actively sought these cards, acquired them, and
generated false claims based on them. Findings 73-79.

Respondent Vo's assertion that his claims activity was an offshoot of his compassion for Vietnamese
refugees and their relatives in Vietnam is self-serving and not credible. Respondent Vo's argument rests on
his uncorroborated testimony that he wrote prescriptions based on Medi-Cal cards provided to him so that
Vietnamese patients could purchase prescription medicines to send to their relatives in Vietnam. I.G. Ex.
6-2/313-314; see Rs.' Statement at 2, 4, 6. The argument is contradicted by the admissions he made in
connection with his guilty plea to state criminal charges. Findings 73-79. Moreover, there is no credible
evidence in this case to show that, even if Respondent Vo wrote the fraudulent prescriptions out of
misguided compassion for his countrymen, he was required, as an adjunct to writing prescriptions, to
fabricate Medi-Cal claims. This case is not about false prescriptions; it is about false Medi-Cal claims, the
proceeds of which Respondent Vo used to his own benefit.

I conclude that the I.G. established Respondent Vo's conduct to have been costly to the government.
Respondent Vo admitted that his unlawful conspiracy netted more than $25,000.00. The cost to the
government of investigating the conspiracy and bringing cases against Respondent Vo certainly greatly
exceeded the amount claimed in the items or services at issue in this case. However, these costs are only a
pale indicator of the costs to the Medi-Cal program which resulted from the provider fraud established in
this case. The real costs arising from this misconduct include the widespread corruption which the
conspiracy generated, and the loss of scarce resources which otherwise might have been used for legitimate
medical needs. Imposing the maximum penalties and assessments permitted by law will serve to recoup
these costs. It will also send a message to other providers not to engage in the kind of misconduct engaged
in by Respondent Vo.

b. Respondent Du

The evidence adduced by the I.G. in this case establishes Respondent Du to be as culpable as her co-
conspirator, Respondent Vo. Respondent Du played a critical role in the conspiracy to defraud Medi-Cal.
Without her involvement and her contribution, Respondent Vo's scheme to defraud Medi-Cal would
certainly have been less successful.

As is noted above, Respondent Du's role in the conspiracy was to recruit drivers and pay them for Medi-
Cal cards. Findings 54-68. Respondent Du was the drivers' primary point of contact with the conspiracy.
She determined the fees the drivers were to receive for their services and maintained written records of the
drivers' activities. I.G. Ex. 5/78. Respondent Du admitted her culpability as a co-conspirator with
Respondent Vo in her guilty plea to state criminal charges. Findings 81-82.

The identical aggravating factors apply to Respondent Du as to Respondent Vo. Respondent Du's
involvement in the conspiracy coincides with Respondent Vo's involvement. It is reasonable to attribute to
Respondent Du, jointly with Respondent Vo, the effects of the conspiracy, including the costs generated
thereby.

Respondent Du has not established the presence of mitigating factors in her case. The same allegations
were filed on her behalf as were filed on behalf of Respondent Vo and, as with Respondent Vo,
Respondent Du offered no evidence to substantiate these allegations.

I conclude that the identical considerations apply in determining appropriate penalties and assessments
against Respondent Du as are applicable to Respondent Vo. As an integral member of the conspiracy,
Respondent Du bears the same burden for the resulting costs to the government as does Respondent Vo.


CONCLUSION

For the reasons set forth in this decision, I impose civil monetary penalties of $128,000.00, and
assessments of $3,890.00, for a total of $131,890.00, against Respondents Vo and Du, jointly and
severally.
