Mich. Comp. Laws § 400.66e
The admitting officer of the university hospital, upon receiving a patient with an authorization issued by a county department of social services under this act, may provide a bed in the hospital and designate the clinic of the hospital to which such person shall be assigned for treatment. The physician or surgeon in charge of the patient shall proceed with proper care to perform such operation and bestow such treatment upon the patient as in his judgment shall be necessary. No compensation shall be charged or received by the admitting officer, or by the medical faculty or by the physician, surgeon or nurses of the university hospital who shall treat and care for the patients, other than the salaries received by them provided by the board of regents of the university. If any such patient has medical or surgical insurance coverage the university hospital may then charge for the service of its medical and surgical staff in amounts not to exceed the amounts available from such insurance coverage. The superintendent shall make and file with the county board of social services an affidavit containing so far as possible an itemized statement of all expenses of hospitalization incurred at said hospital in care of patients admitted under this act in accordance with the usual rates therefor fixed by the regents of the university. He shall also make reports at suitable intervals to the county department which issued the order, stating the condition of the patient and the expense incurred. No county shall be liable for expenses incurred after the expiration date of the order of the county department unless a new order is obtained.
