Miss. Code § 41-9-17
The licensing agency shall adopt, amend, promulgate and enforce such rules, regulations and standards with respect to all hospitals to be licensed under Section 41-9-11 as may be designed to further the accomplishment of the purposes of Sections 41-9-1 through 41-9-35 in promoting safe and adequate treatment of individuals in hospitals in the interest of public health, safety and welfare. Any rule, regulation or standard adopted hereunder shall be considered as promulgated and effective from and after the time the same is recorded and indexed in a book to be maintained by the licensing agency in its main office in the State of Mississippi, entitled "Minimum Standard of Operation for Mississippi Hospitals." Said book shall be open and available to all hospitals and the public generally at all reasonable times. Upon the adoption of any such rule, regulation or standard, the licensing agency shall mail copies thereof to all hospitals in the state which have filed with said agency their names and addresses for this purpose, but the failure to mail the same or the failure of the hospital to receive the same shall in nowise affect the validity thereof. No such rules, regulations or standards shall be adopted or enforced which would have the effect of denying a license to a hospital or other institution required to be licensed, solely by reason of the school or system of practice employed or permitted to be employed therein.
