Tennessee Department of Health and Environment, DAB No. 898 (1987)

DEPARTMENTAL GRANT APPEALS BOARD

Department of Health and Human Services

SUBJECT:  Tennessee Department of Health and Environment

Docket No. 87-11
Decision No. 898

DATE:  September 11, 1987

DECISION

The Tennessee Department of Health and Environment (State) appealed the
disallowance by the Health Care Financing Administration (HCFA) of
$957,866 in federal financial participation (FFP) claimed under Title
XIX (Medicaid) of the Social Security Act (Act).  The disallowance was
based on a determination that the State had not returned to HCFA the
federal share of overpayments made by the State to providers of Medicaid
services.  HCFA adopted the findings by an audit firm which used
statistical sampling to determine the amount of the overpayments.

The major issue presented is whether HCFA is authorized to estimate
provider overpayments through the use of a statistical sample.  For the
reasons described below, we find that HCFA is entitled to use
statistical sampling to determine the amount of these overpayments.
Accordingly, we affirm the disallowance in principle.  HCFA has agreed,
however, to provide the State the opportunity to show that, even though
specific overpayments were listed in the sample as "outstanding," in
fact they have been collected and the federal share returned to HCFA.

Case Background

On August 19, 1981, the State entered into a five-year contract with the
Computer Science Corporation (CSC) for Medicaid fiscal agent services.
Soon CSC experienced claim processing problems as a large backlog of
claims developed.  On May 11, 1982, the State entered into a contract
with the accounting firm of Deloitte Haskins & Sells (DHS) to review
CSC's performance as fiscal agent during the period January 1, 1982
through April 30, 1982.  On July 19, 1982, DHS issued its review of
CSC's performance.  HCFA Ex. D.  The DHS review detailed.numerous
failings in CSC's performance.  Such problems as duplicate payments,
payments in excess of amounts billed, and payments for excessive
hospital stays were identified.  The State then extended its contract
with DHS to include a review of CSC's progress for the months of May and
June 1982.  One of DHS' tasks under this contract was "[e]stimating the
dollar magnitude of erroneous payments."  HCFA Ex. E, p. 1.  DHS
estimated that the dollar value of overpayments through June was
probably in the range of $3,500,000 to $4,000,000.  State Ex. A,
Appendix B, p. 4.  The State subsequently notified CSC that, as of
September 30, 1982, it was terminating the CSC Medicaid Fiscal Agent
contract.  The State estimated that over 4,000,000 claims would have to
be reprocessed because of CSC errors.  HCFA Ex. G, p. 5.

On November 3, 1985, HCFA entered into a contract with the Tennessee
State Auditor's office to have that office report to HCFA on the
feasibility of reprocessing claims initially processed by CSC and to
determine the most cost effective method of recouping overpayments
"without the reprocessing of claims." Id., p. 6.  The Auditor's office
employed DHS to perform this task.  On April 30, 1986, DHS issued its
report, entitled "Feasibility of Reprocessing Medicaid Claims
Adjudicated During the Period January 1 through September 30, 1982."
State Ex. A, Appendix A.  The purposes of this review were to:

       -- determine what portion of the overpayment had been recovered
          subsequent to the 1982 report;

       -- develop, based on a new statistical sample, an estimate of the
          outstanding amount of overpayments for the period;

       -- estimate the cost of reprocessing the claims; and

       -- make a recommendation of the reasonableness of reprocessing
          claims for the period.

Id., p. 3.

DHS drew new statistical samples of claims processed during the period
for the claim types and conditions evaluated in the original study.
Employing a standard statistical sampling method, Cumulative Monetary
Accounts Sampling, DHS estimated the amount of outstanding overpayments
for the selected group of claims as $1,397,732 ($957,866 FFP) for the
period January 1 through June 30, 1982. 1/  Id., pp. 10-27.  DHS then
estimated that the total cost of reprocessing the claims for the period
January 1 through June 30, 1982 would be $5,241,286.  Id., p. 30. Since
the cost of reprocessing the claims would remain far in excess of the
potential recovery of overpayments, DHS recommended that the claims not
be reprocessed.  Id., p. 31.

On the basis of the DHS reports, HCFA issued a  disallowance in the
amount of $957,866, citing section 1903(d)(2) of the Act as the
authority for the recovery of the federal share of the overpayments.
That section provides for reduction of federal payments to a state "to
the extent of any overpayment . . . which the Secretary determines was
made . . . to such State for any prior quarter and with respect to which
adjustment has not already been made. . . ."

Analysis

I.    Can HCFA use statistical sampling to arrive at a disallowance of
      Medicaid overpayments?

As noted above, HCFA adopted the findings of the 1986 DHS report in
determining the disallowance amount.  DHS had not examined all of the
approximately four million claims disputed under the CSC contract, but
rather had used statistical sampling to arrive at an estimate of the
overpayments made during the period in question and still unrecovered.

The State argued that HCFA is not authorized by statute to estimate
overpayments through the use of sample claims. 2/  The State contended
that section 1903(d)(2) of the Act, the section cited by HCFA as the
statutory authority for the recoupment of overpayments, does not
expressly authorize the Secretary of the Department of Health and Human
Services to use sampling in the estimation of any overpayment.  In
contrast, the State pointed out, Congress expressly authorized the use
of sampling in section 1903(u) of the Act to determine target error
rates with respect to Medicaid eligibility.  Citing Russello v. United
States, 464 U.S. 16 (1983), the State argued, "Where Congress includes
particular language in one section of a statute but omits it in another
section of the same act, it is generally presumed that Congress acts
intentionally and purposely in the disparate inclusion or exclusion."
State's Brief, p. 11.  The State continued, "Had Congress intended to
authorize the use of sampling as a means of identifying overpayments
pursuant to section 1903(d), it would have expressly provided so, just
as it did in subsection (u) of section 1903 for Medicaid eligibility
quality control."  Id.

The State also argued alternatively, in the event the Board should hold
that HCFA has the statutory authority to use sampling to determine
overpayments, that such authority, unless self-executing, must be
effectuated through rules promulgated under the Administrative Procedure
Act (APA), 5 U.S.C. 551 et seq.  The State asserted that the use of
sampling, to carry out the policy stated in section 1903(d) of the Act
to increase or reduce Medicaid payments to states because of
underpayments or overpayments to providers, is a substantive rule
requiring notice and comment rulemaking.  The State concluded that the
Secretary's failure to promulgate such a rule renders the procedure of
statistical sampling invalid under the APA.

At the outset we note that the State has not disputed the Secretary's
authority, upheld in Board and court decisions, to recover the federal
share of overpayments under section 1903(d)(2) of the Act.  See, e.g.,
California Department of Health Services, Decision No. 619 (1985), and
Massachusetts v.  Secretary, 749 F.2d 89 (1st Cir. 1984).  Section
1903(a)(1) provides that FFP will be available only for payments for
medical assistance made in accordance with the State Medicaid plan.  The
DHS reports showed, and the State did not contest, that the overpayments
at issue were clear violations of the State plan. The record
unambiguously indicates that CSC's problems with processing the claims
gave rise to unallowable expenditures, most notably for duplicate
payments.

As it is undisputed, then, that unallowable payments were made, the
question is how to determine the amount of those payments. Approximately
four million claims for questionable expenditures were disputed.  In
order to arrive at an exact amount of the overpayments, the State
apparently would have each individual claim examined.  We find this
patently impracticable and unreasonable.  Given the magnitude of the
disputed claims, the only logical cost-effective method to estimate the
amount of the overpayments is through some type of statistical sampling.
An examination of the legislative history of section 1116(d) of the Act,
which establishes procedures when the Secretary issues a disallowance
(one form of the determination of an overpayment under section
1903(d)(2)), reveals that Congress contemplated the Secretary using
various audit techniques in determining the amount of unallowable costs.
See 1965 U.S. CODE CONG. & ADMIN.  NEWS 2, at 2103.  One such commonly
accepted technique is statistical sampling.

In University of California -- General Purpose Equipment, Decision No.
118 (1980), the Board stated that statistical sampling has been accepted
as a basis for determining adjudicative facts.  As such, statistical
sampling can be reliable evidence concerning an amount of unallowable
costs.  The Board thus saw the use of statistical sampling as an
evidentiary question, not as an action requiring specific statutory
authority for a federal agency to use it.  In Ohio Department of Public
Welfare, Decision No. 226 (1981), the Board upheld HCFA's general use of
sampling to determine the amount of a disallowance.  Both the Board and
the courts have upheld the use of statistical sampling evidence as a
basis for a disallowance, where claim-by-claim review is not feasible.
See, e.g., Georgia v.  Califano, 446 F. Supp. 404 (N.D. Ga. 1977), and
California Department of Social Services, Decision No. 816 (1986).

We do not view the fact that Congress explicitly authorized statistical
sampling under section 1903(u) of the Act as barring the Secretary from
using sampling to determine disallowances under other sections of the
Act.  A reading of the legislative history for section 1903(u) reveals
no indication that Congress attached any special significance to the use
of statistical sampling there or intended 1903(u) to be the exclusive
area where statistical sampling could be used.  See 1982 U.S. CODE CONG.
& ADMIN. NEWS 2, at 815 and 1219.

Indeed, viewed in the context of the pre-existing quality control
program (which provided by regulation for a sampling method to be used
in establishing disallowances for certain types of state errors), the
enactment of section 1903(u) in effect ratified the Secretary's
interpretation that use of sampling was within the authority to
determine overpayments granted in section 1903(d)(2).

We do not consider Russello to be applicable here.  That case involved
an interpretation of the Racketeer Influenced and Corrupt Organization
(RICO) chapter of the Organized Crime Control Act of 1970.  Unlike RICO,
which was enacted by Congress in a single piece of legislation, the Act,
with its Medicaid provisions, has developed through a series of acts
passed by different Congresses.  As such, it does not have the internal
consistency of a single piece of legislation.  We therefore do not find
that because statistical sampling is mentioned only at section 1903(u)
of the Act the Secretary is precluded from using it under other sections
of the Act.

Once again, given the explicit Congressional authority in section
1903(d)(2) to the Secretary to adjust for overpayments and the millions
of disputed claims in this case, we consider it a question of
reasonableness and cost-effectiveness that the Secretary be allowed to
use statistical sampling.  The Board has also recognized the reliability
of statistical sampling:  "In simple terms, valid statistical sampling
will produce a result which has a high degree of probability of being at
least as good as a full-scale review."  California Department of Social
Services, Decision No. 816 (1986), p. 5.

As to the State's alternate argument that the Secretary's use of
statistical sampling should be considered a "rule" within the context of
the APA, we note that the procedures for notice and comment rulemaking
set forth in the APA do not apply to "interpretative rules, general
statements of policy, or rules of agency organization, procedure, or
practice."  5 U.S.C. 553 (b)(3)(A).  The State relied on W.C. v. Bowen,
807 F.2d 1502 (9th Cir. 1987), where the court detailed two factors in
determining whether a rule is substantive or interpretative.  First, if
the rule effects a change in existing law or policy or affects
individual rights and obligations, the rule is substantive; if the rule
is only indicative of an agency's interpretation of existing law or
policy, it is interpretative.  Second, if the rule is promulgated
pursuant to statutory direction or under statutory authority, it is a
substantive rule; if the agency does not exercise delegated legislative
power to promulgate the rule, it is an interpretative rule.  In W.C. v.
Bowen, the court found that a procedure for reviewing the decisions of
administrative law judges in disability claims under Title II of the
Act, the Bellmon Review Program, changed existing policy and was issued
pursuant to statutory direction.  The court therefore found it was a
substantive rule requiring notice and comment rulemaking.

Contrary to the State's arguments, we find that the criteria set forth
in W.C. v. Bowen support a conclusion that HCFA's use of statistical
sampling is not a rule requiring notice and comment rulemaking.  The
Secretary's use of sampling as an audit technique is not a change in
existing law or policy and does not affect individual rights or
obligations.  Nor was statistical sampling developed as a result of
statutory direction or authority.  Statistical sampling, a generally
accepted audit technique, is but one of the procedural methods used by
the Secretary to determine disallowances under the Act.

Moreover, this is not a situation where lack of actual or constructive
notice to the State precludes application of the use of sampling under
the APA. 5 U.S.C. 552(a)(1).  The State is not adversely affected by the
mere use of a sampling audit technique. The sampling is simply a means
of establishing the amount of payments violating state plan provisions.
Given the problems with CSC's claims processing, HCFA could have
required the State to document allowability of its payments during this
period on a claim-by-claim basis.  Use of a valid statistical sampling
technique instead to measure the extent of unallowable payments is a
cost-effective, less burdensome means which benefits the State as well
as HCFA.

II.   Is the State foreclosed from challenging specific findings in the
      DHS reports?

While we find that HCFA may use statistical sampling to estimate a
disallowance, we also hold that the State must be given an opportunity
to contest specific audit findings.  The State did not challenge the
validity and reliability of the statistical sampling used in the DHS
audit. 3/  The State did, however, argue that HCFA failed to consider
the $4,493,947 in overpayments actually recovered by the State, noted on
page 6 of the 1986 DHS report, for a set-off against the estimated
overpayments.  The State contended that its records indicate that the
outstanding "negative balance" in its accounts receivable for the period
in question is only $72,875.59.  State Ex. B, Appendix C.  The State
declared that it intended to trace the overpayments reflected in the
sampled claims, by claim and/or recipient, to determine if they have
been recovered.  State Ex. B, p. 2.

Contrary to the State's assertions, DHS did take into account some of
the recoveries made by the State.  It is possible, however, that other
recoveries may be related to the sampled claims, but have not been
sufficiently identified to correlate to specific claims.  In a telephone
conference, HCFA agreed to give the State the opportunity to contest
individual sample claims by showing that the State had already made
recoveries of some of the sampled overpayments which the auditors did
not take into account.

We accordingly find that the State must be allowed to show that specific
findings reflected in the DHS reports are incorrect.  If HCFA should
reject the evidence the State produces for specific claims, the State
will be permitted to return to the Board to appeal those negative
determinations by HCFA.

III.    Can HCFA deny FFP for reprocessing the claims originally
        processed by CSC?

The State argued that it would be denied a full opportunity to contest
the disallowance unless it was given the chance to reprocess the claims
at issue.  The State supplied a September 22, 1986 letter from HCFA,
however, which stated that HCFA had already paid FFP for the processing
of the claims, when CSC had done it, and that HCFA's policy was that it
"will continue to pay for the operational processing of claims, but once
and only once."  State Ex. C, Appendix C, p. 2.  The State maintained
that this demonstrated inconsistency on HCFA's part as HCFA had
previously stated that it would not approve a contract for fiscal agent
services unless the contract contained a provision allowing the State to
unilaterally reprocess claims if the State determined that was
necessary.  The State contended that that contract, approved by HCFA,
gives the State, not HCFA, the authority to decide if and when claims
will be reprocessed.

The administrative cost of reprocessing the claims is not directly
before the Board as the State has not yet incurred or submitted that
cost to HCFA.  The issue before us is the propriety of HCFA's
disallowance of the federal share of the overpayments to the providers,
$957,866.  The State did not indicate, outside of general allegations of
fairness, how HCFA's refusal to supply FFP to reprocess the claims is a
basis for overturning this disallowance.

The allegations of inconsistency on HCFA's part are unsupported. The
State retains its authority to reprocess if it wishes; HCFA has simply
taken the ostensibly reasonable and consistent position that no federal
funding will be available for what is essentially a duplicative
activity.

We also reject the State's argument that, since HCFA based the
disallowance on a sample, the State must reprocess "to determine which,
if any, claims are at issue."  State's Reply Brief, p. 4. The State was
provided with a list of disallowed sampled items, has had a full
opportunity to dispute the audit findings on the sample payment errors,
and will have the opportunity to show that additional recoveries should
have been applied to the sample items.  The State would perhaps need to
reprocess to identify and recoup overpayments not specifically included
in the  sample, but we doubt that, even with federal participation, the
State would choose to expend approximately five million dollars to
collect some one million dollars.

Conclusion

For the reasons stated above, we affirm the disallowance in principle.
As indicated above, the State has the opportunity to show, within 30
days or such other reasonable time period as HCFA may establish, that
specific overpayments in the sampled claims have already been collected
and the federal share returned to HCFA.  If.HCFA should reject the
State's documentation for certain claims, the State will be permitted to
appeal any negative determinations by HCFA to this Board.

1.     While the DHS report's principal objective was to ascertain the
cost of reprocessing claims for the nine-month period January 1 to
September 30, 1982, the report estimated outstanding overpayments only
for the period January 1 through June 30, 1982.

2.     Initially the State also argued that the Board should reverse the
disallowance because HCFA's disallowance decision failed to contain, as
required by regulation, sufficient detail to provide the State with an
adequate opportunity to respond.  In the course of the appeal, however,
HCFA provided the State with various documentation that resulted in the
State terming the issue of the adequacy of the disallowance decision
"moot." State's Reply Brief, p. 2.

3.     The State did contest whether the 1986 DHS report, on which HCFA
based its disallowance for outstanding overpayment, was, in fact, an
"audit" that could be used as the basis of a disallowance.  According to
the State, the report was intended to be only a feasibility study on the
economies of reprocessing certain claims and not a method for
identifying the amount of outstanding overpayments.  In response, we
refer to the contract HCFA executed with the Tennessee State Auditor's
office (State Ex. A, Appendix B), which variously described the
contracted work as an "audit report" (p. 3) or an "audit survey" (p. 5).
The 1986 DHS review itself describes one of its purposes as to determine
an estimate of outstanding overpayments.  State Ex. A, Appendix B, p.
