441—76.8 (249A) Investigation by quality control or the department of inspections and appeals. The client shall cooperate with the department when the client's case is selected by quality control or the department of inspections and appeals for verification of eligibility unless the investigation revolves solely around the circumstances of a person whose income and resources do not affect medical assistance eligibility. (See department of inspections and appeals rules in 481—Chapter 72.) Failure to do so shall serve as a basis for cancellation of assistance unless the Medicaid eligibility is determined by the Social Security Administration. Once a person's eligibility is denied or canceled for failure to cooperate, the person may reapply but shall not be determined eligible until cooperation occurs.
