La. Public Health and Safety § 40:1086.21
A healthcare provider attending a newborn child shall administer appropriate testing for cytomegalovirus if the newborn fails the newborn hearing screen and, in the exercise of professional judgment, the healthcare provider believes that the testing would be in the best interest of the newborn. Any testing for cytomegalovirus provided in accordance with the provisions of this Section shall be considered medically necessary and shall not be denied on the basis for failing to meet any applicable medically necessary standards or requirements by any health insurance issuer which otherwise provides coverage for the testing. The Louisiana Department of Health shall provide payment to all Medicaid providers for the costs incurred as a result of the administration of testing pursuant to the provisions of this Section. Payment shall be made by the department within thirty days of receiving a claim for payment from a healthcare provider.
