As used in this section unless the context requires a different meaning, “hospital” means a hospital as defined in § 32.1-123 or 37.2-100. State agencies shall make or cause to be made only such inspections of hospitals as are necessary to carry out the various obligations imposed on each agency by applicable state and federal laws and regulations. Any on-site inspection by a state agency or a division or unit thereof that substantially complies with the inspection requirements of any other state agency or any other division or unit of the inspecting agency charged with making similar inspections shall be accepted as an equivalent inspection in lieu of an on-site inspection by said agency or by a division or unit of the inspecting agency. A state agency shall coordinate its hospital inspections both internally and with those required by other state agencies so as to ensure that the requirements of this section are met. No hospital shall receive additional inspections until all other licensed hospitals in the Commonwealth have also been inspected, unless the additional inspections are (i) necessary to follow up on a preoperational inspection or one or more violations, (ii) required by a uniformly applied risk-based schedule established by the Department, (iii) necessary to investigate a complaint regarding the hospital, or (iv) otherwise deemed necessary by the Commissioner or his designee to protect the health and safety of the public. Notwithstanding any provision of law to the contrary, all hospitals licensed by the Department of Health or Department of Behavioral Health and Developmental Services that have been certified under the provisions of Title XVIII of the Social Security Act for hospital or psychiatric services or that have obtained accreditation from a national accrediting organization granted authority by the Centers for Medicare and Medicaid Services to ensure compliance with Medicare conditions of participation pursuant to § 1865 of Title XVIII of the Social Security Act (42 U.S.C. § 1395bb) may be subject to inspections so long as such certification or accreditation is maintained but only to the extent necessary to ensure the public health and safety.
