Mich. Comp. Laws § 752.1007

Sec. 7. (1) In a prosecution under this act, it shall not be necessary to show that the person had knowledge of similar acts having been performed in the past by a person acting on the person's behalf, nor to show that the person had actual notice that the acts by the persons acting on the person's behalf occurred, to establish the fact that a false statement or representation was knowingly made. (2) It shall be a rebuttable presumption that a person knowingly made a claim for a health care benefit if the person's actual, facsimile, stamped, typewritten, or similar signature is used on the form required for the making of the claim for the health care benefit. (3) If a claim for a health care benefit is made by means of computer billing tapes or other electronic means, it shall be a rebuttable presumption that the person knowingly made the claim if the person has advised the health care corporation or health care insurer in writing that claims for health care benefits will be submitted by use of computer billing tapes or other electronic means. (4) In any civil or criminal action under this act the certificate of an authorized agent of the health care corporation or health care insurer setting forth that documentary material or any compilation thereof is an authentic record or compilation of records of the health care corporation or health care insurer shall create a rebuttable presumption that the record or compilation is authentic.
