PER CURIAM.
Petitioner appeals as of right from a March 31, 1988, circuit court opinion and order upholding a February 14, 1986, recommendation by a hearing referee and a February 27, 1986, final decision and order by the Department of Social Services requiring petitioner to repay the department $120,000 in medicaid overpayments. The amount of overpayment owed was determined by an audit of petitioner's medicaid claims for a two-year period from January 1, 1981, through December 31, 1982. The overpayment was computed through the use of a statistical random-sampling extrapolation formula wherein the DSS would examine a certain percentage of cases within the two-year period, make a determination of the percentage of those cases that were overcharged, and apply that percentage to the total number of cases during the two-year period. On appeal, petitioner alleges that the hearing referee incorrectly applied the burden of proof to petitioner and adopted the wrong standard for medical necessity. We disagree and affirm.
The hearing procedures involved in assessing overpayments to a medicaid provider have been *549 upheld by this Court and were determined not to be a violation of due process where the provider is given an opportunity to rebut the initial determination of overpayment. Quality Clinical Laboratories, Inc v Dep't of Social Services, 141 Mich App 597, 601; 367 NW2d 390 (1985). The extrapolation process used by the DSS creates a rebuttable presumption placing the burden on the physician to demonstrate that the department's calculations are inaccurate. At all times the burden is on the physician to prove entitlement to welfare monies. Illinois Physicians Union v Miller, 675 F2d 151, 154 (CA 7, 1982). On appeal, petitioner objects to the hearing referee's imposing on him the burden of proof on the issue of his entitlement to the disputed payments by requiring that he demonstrate that the department's calculations are inaccurate. The Miller court specifically allowed the state to place the burden on the physician to demonstrate that the department's calculations were inaccurate. Id. Further, this Court in Zenith Industrial Corp v Dep't of Treasury, 130 Mich App 464, 468; 343 NW2d 495 (1983), held that an administrative agency may allocate the burden of proof by ad hoc decision so long as the allocation is consistent with the legislative scheme being administered. Considering the legislative scheme underlying the joint federal-state medicaid program as announced in Miller, we find that the hearing referee did not err in placing the burden of proof on petitioner to establish his entitlement to payment.
Petitioner also alleges that the hearing referee erred in applying the wrong standard for medical necessity. We disagree. On review of the referee's recommended decision, we find that the referee supported the department's disallowance on the basis that the patients' medical records did not *550 establish the medical necessity for prescribing the procedures. The hearing referee held that the patients' histories, signs, symptoms, physical findings, and diagnoses failed to establish the need for the procedures on the basis of the standards of practice of an osteopathic physician. We find that the basis of the hearing referee's decision was petitioner's failure to compile and maintain comprehensive case histories and notations of patient complaints, signs, and symptoms that would support the laboratory testing which was revealed by the audit. The hearing referee did not apply the wrong standard. On review of the referee's recommendation, we conclude that the final decision requiring petitioner to repay the DSS $120,000 in medicaid overpayments is supported by competent, material, and substantial evidence on the whole record. Quality Clinical Laboratories, supra at 599.
Affirmed.
